Big Numbers, Small Numbers

Guest Post by Willis Eschenbach

I read a paper today that said that there are no less than 270,000,000 kilograms of plastic in the ocean, which is about half a billion pounds plus of plastic. So … is this a big number or a small number?

The story is at the Guardian, and they’ve illustrated it with the following picture:

guardian plastic in ocean

Regarding the story, as usual the Guardian doesn’t disappoint—it hypes the danger of the half-billion pounds of plastic. Hey, good news doesn’t sell newspapers, so I can’t fault them. In any case, they say:

More than five trillion pieces of plastic, collectively weighing nearly 269,000 tonnes, are floating in the world’s oceans, causing damage throughout the food chain, new research has found.

Now, I suppose that the good folks at the Grauniad think that with their picture they are showing the “damage throughout the food chain” that they claim plastics cause in the ocean … but look at the picture and think about it for a moment.

Does it look like a) that chunk of plastic is inimical to sea life … or does it look like b) that chunk of plastic is acting a substrate upon which abundant sea life is living and serving as fish food? Call me crazy but I’m going for Choice b), you can see the little striped fish chowing down. Now I know that not all plastic is good for sea life … but that plastic certainly is.

However, I started out with the question about whether 270,000,000 kilogrammes is a big number or a small number. Looking at the extent of the ocean gives us a very different picture … because it turns out that the 270,000,000 kilograms of plastic works out to 200 grams of plastic per cubic kilometer of the ocean. Or in old-school measurements, that’s just under two pounds of plastic per cubic mile of seawater. (Some commenters have noted that most of the debris is at or near the surface, so if you prefer, it’s about 900 grams of plastic per square kilometer of ocean surface.)

Now, I’m willing to agree that there are some kinds of plastic that are likely inimical to sealife. Nylon fishing nets that have been lost and gone adrift, for example, continue to kill fish. But the fish aren’t wasted, they’re eaten in turn by a combination of larger and smaller fish until the net washes ashore. So the nets are just another predator. Not saying I like that, I don’t, particularly when they catch whales and other sea mammals … but it’s not the end of the ocean.

And as for the other small pieces of random plastic … well, I just can’t get all that passionate about the dangers of 200 grams of plastic for every BILLION tonnes of sea water, or if you prefer, the dangers of 900 grams of plastic for every square kilometre of ocean surface (1 cubic km = one billion tonnes).

Now, I can hear you thinking, but Willis, what about the great Pacific Gyre, where the plastic collects? First, it’s not like most people think, where you could walk on the plastic and there are islands and such. The density is much higher than the global average, but it’s still only about 2-3 kg per cubic kilometre, or about 5 kg/square km.

However, as a long-time fisherman, I’d bet big money that there is MORE sea life in the Gyre than in equivalent blue-water ocean near the Gyre. The blue water is a desert, in part because there’s nothing for life to grow on. Many kinds of sea life require a “substrate”, something solid to attach to so it can grow. As a result, anything that floats, and I mean anything, will rapidly attract life, just as in the Guardian’s “scary” picture above.

In closing, I don’t like plastic in the ocean, and I’m very, very conscious about it when I’m at sea. I never throw plastic into the ocean. However, as an ocean problem, it’s way, way below things like overfishing and pollution. Those are the real dangers, not a couple hundred grams of plastic in each billion tons of sea water. That’s a small number.

Best to all,

Radiation worries? Here is a table of common items from World Nuclear .Orgs web site
Table 8: Activity concentrations of NORM in building materials (Bq/kg)
Material Ra-226 Th-232 K-40
Concrete 1-250 1-190 5-1570
Aerated concrete 109818 <1-220 180-1600
Clay bricks 1-200 1-200 60-2000
Sand-lime bricks and sandstone 18415 10959 5-700
Natural building stones 1-500 1-310 767011
Natural gypsum <1-70 <1-100 7-280
Cement 7-180 7-240 24-850
Tiles 30-200 20-200 160-1410
Phosphogypsum 4-700 19360 25-120
Blast furnace slag stone and cement 30-120 30-220 –
So, while near the Fukishima (and Chernobyl) reactors the levels are lethal or very dangerous, ocean water levels of 3Bq/m3 are (as the article states) many orders of magnitude below any concern, considering that natural radiation is around 14Bq/L – and a liter is much smaller than a cubic meter…(what your original article puts forward – the 3Bq/m3)
The average radioactivity of seawater is about 14 Bq/L of which 88% is from naturally occurring potassium-40 (K-40). About 7% is from anthropogenic fallout from atmospheric nuclear weapons testing and nuclear accidents like Chernobyl (1986) and Fukushima Daiichi (2011). So there is about 13 Bq/L of natural radioactivity on average is the oceans. The rest of both links is also interesting to read to put some perspective on radiation and everyday life.
On the other hand Solar Power Satellites seem to be the best way to generate power for humans, we can do it with current technology and have real power transmitted to earth within ten years. Better than the payback for fusion research has been (so far)!

With regard to solar satellites I recall similar claims that they would be viable in a decade. Trouble is those claims were made 40 years ago. In 1973 Peter Glaser was granted U.S. patent number 3,781,647 for his method of transmitting power from a satellite to ground using microwaves from a very large antenna (up to one square kilometer) on the satellite to a much larger one, now known as a rectenna, on the ground.
Now setting aside the technical issues involved in the transmission and the associated risks the real killer is the cost to orbit of the SPS. Studies showed launch costs need to be around L $100–$200 per kilogram of payload to low Earth orbit are needed if SPS are to be economically viable. Current launch costs vary from $3000 to $13000 per kg, Larger launch weights tend to be in the more expensive range with the average for sizable satellites being around $10,000 per kg.

So far, the payback on fusion is zero. And the payback on solar power satellites is zero. Are you saying one zero is better than the other?
If I had to choose I’d put my money on fusion. Both technologies could be made to work. When they’re both viable I’d guess fusion would be hundreds of times cheaper.

Jolly Farmer: Re “skyrocketing” beta measurements. Beta emitters are created in our atmosphere as the result of cosmic radiation and high energy particles interacting with the earth’s atmospheric molecules. The predominant beta emitter is carbon-14 and other beta emitting nuclides include H-3 and Be-10. A nice blast from the sun will increase the number of beta emitters in the atmosphere. Just saying that there is an uptick in atmospheric beta measurements doesn’t mean squat without an analysis of the nuclide(s) causing the uptick. If an analysis shows an uptick in these natural radionuclides, it is probably due to the sun. Other natural air borne beta emitters includes Radon daughter products which are and can be released via a number of mechanisms including man stirring up the earth, a volcano or a forest fire. The article you cite is just another alarmist, Chicken Little article. I know for a fact that the cited measuring stations analyze for the nuclides. The article made no attempt to include this information. Deception by omission.

The levels of those isotopes wold be directly related to the age, composition and source of the materials. Uranium accumulates in clays and silts for instance, so there would be background levels of Cs and Sr in the those materials in proportion to the parent isotope levels. Same goes for sea water. You also want to toss in K-40, commonly found in bananas and which occurs in the bananas at such levels that large shipments can occasionally trip radiation alarms in shipping terminals.
As regards radiation levels, you run into some issues that are “precautionary” – think lawyer speak – as opposed to “scientific.” Current assessments of risk from radiation are based on a linear extrapolation from known levels of serious hazard and a simpleminded assumption that less is always better. However, there is increasing evidence that if exposures drop below> certain levels then the kinds of disease processes associated with radiation begin to increase once more. There is also some active research into why this might be and the best evidence seems to be that we actually need some exposure to keep chromosomal repair mechanisms tuned up and operating properly. Too much radiation and they are swamped by damage and simply can’t keep up. Too little and they slack off and damage accumulates without repair. There is no fixed level of “natural” background radiation and in fact Svensmark’s cosmic-ray hypothesis regarding cloud formation leans on “natural” cosmic radiation variability, mediated by the sun, as a causal agent in cloud formation.

Well Keith it sounds to me that “Rectenna” is an appropriate name for that contraption; it’s really a shitty idea.
The problem of gathering solar energy is quite simple to understand.
At the moment without being touched by human hand, solar energy reaches us at ground level at about 1KW/m^2 under ideal conditions. I have an electricity source just a few feet from where I am typing that is several megawatts per square meter.
So the trouble with free clean green renewable solar energy, is that it is spread so thinly, and it is NOT cheap to gather that free stuff up.
Even so, it fries our brains if we spend too much time out in it at that radiant incidence level.
So if we gather it in space where we can get it cranked all the way up to 1360 W/m^2 (I thought the number was 342 ?) Wow, and we have to launch all that tonnage of collector up into orbit for a 36% gain in energy density. Remember how damn big that Tonopah collector is in California ?
So now we transmit if down to earth. Whooopee !! Do we transmit it to reach earth at more than 1,000 W/m^2 so we have a smaller cheaper collector; but one that will incinerate our brains faster, or do we thin it out some more, so that surfers can play in it all day without getting rectennated.
So now how big does a rectennal solar farm have to be ??
Seems like this makes loons look highly intelligent.
Well they are pretty anyhow.

Well Chris, you would be betting on a sure loser. What is your basis for stating: “Both Technologies could be made to work. ” ??
Fusion does work in the sun and other stars, but the real energy source there is Gravitation, which sucks.
There isn’t enough raw materials or space, on earth to make a gravity powered fusion reactor.
And the only other available force to use to create controlled fusion is the Coulomb force of electro-magnetism, and EM does not suck; it blows.
So trying to compress a hot plasma with the Coulomb force, is like trying to PUSH a railway train full of coal with a piece of rope.
There’s an annoying little theorem, known as Earnshaw’s theorem, that says that can’t work.
So nyet on earthly fusion.

That’s one of the things about nuclear science. Before we ever touched it, or used it, or created bombs with it… radiation was extremely well understood. We have the ability to record levels of radioactivity that are as harmless as a banana. So whenever I see these numbers about Fukushima, or Three Mile Island, or for that matter even Chernobyl and Pripyat, I don’t worry.
Since I spent several years working at a nuclear facility, I had to take courses and learn a lot more about it than the average person ever does. I still remember taking a meter into downtown Banff (in the mountains) and recording levels higher than in our shop.
I trust the people involved in tracking Fukushima, because I used to work with one of them. I’ve never met a more honest man, or a group of people more dedicated to safety.

Well jolly, the articles you cite about the “ice wall” are actually about the trenches, a completely different issue. The ice wall is technology that has been used before (although not specifically for radioactive contamination). Without it many tunnelling projects, like Boston’s “Big Dig”, would have been much more difficult.
As for the USS Reagan, they got exposed to less radiation than the flight crew on a trans-Pacidic passenger plane. And citing enenews is a joke right?

@ Jolly Farmer:
Natural Radioactivity by the Ocean (Per Liter average for each nuclide listed first; total activity in oceans follows); Activity
Nuclide Per Liter Pacific Atlantic All Oceans
Uranium 33 mBq/L 22 EBq 11 EBq 41 EBq
Potassium 11 Bq/L 7400 EBq 3300 EBq 14000 EBq

The activities used in the table are from 1971 Radioactivity in the Marine Environment, National Academy of Sciences. The total activities calculated for individual and all oceans are derived from the first column multiplied by the volume (data available) of the oceans. 1 Bq= 1 disintegration/second.
EBq = 10E18 (or 1,000,000,000,000,000,000) PBq=10E21. There are other naturally occurring nuclides in the ocean. The per liter sum of just these five nuclides is 12.13 Bq/L.
The articles you cite indicate up to 2 Bq/liter of Cs-137 detected in the water. As one article indicates, this activity is well below any health concern standards. As all sea critters are bathed in 12 Bq/L anyway, does anyone think an extra 1 or 2 Bq is going to make any difference or danger? Activity levels were likely twice as high when life began in the seas and sea critters are well adapted these extremely low levels of radiation.

Jolly Farmer: you ask how much radioactivity there is in common building materials. Here is the Health Physics Society website that will give you lots of information on background radiation. Note that data is presented in Ci and Bq. These are just different units that measure the same thing. Building materials are listed about halfway down.
Cesium is a biological analog of calcium. Calcium is used in all sorts of biological processes, e.g. neuronal transmissions and bone building. There is a vast amount of calcium in the oceans. Biological organisms will take-up cesium proportionally to the calcium/cesium concentrations. Therefore there is normally very little take-up of cesium in ocean organisms because there is very, very little radioactive cesium in the oceans. Additionally, the natural turn-over of cesium in an organism mimics the natural turnover of calcium so it is unlikely any accumulative effect will be seen. Disclaimer: I can’t be sure this is true for all oceanic organisms, but I have some knowledge it is true in fish. Fish caught within the relatively undiluted plume near Fukishima did contain radionuclides from it, but I’ll have to find the studies that tell what nuclides and how much. My recollection is that the fish were approaching concern levels, but not considered particularly dangerous.

Cesium 137 is radioactive but natural cesium extracted from a mine is not. Most cesium is used in making a liquid called cesium formate which is a low viscosity heavy liquid (2.4 g/l or ~ 21/2 times the weight of a litre of water). It is used as a drilling fluid in deep oil wells (North Sea, etc.) for floating the drill cuttings and as a counterweight to the oil in the reservoir to control well finishing. Alternative solid powders slurried in the drill water for weighting agents, like barite, make the fluid too viscous for deep wells.
Remarkably, tests on toxicity showed cesium formate it to be completely benign to humans and the environment. It is inert and even at high temperatures and pressures at depth with harsh reactants like hydrogen sulphide in the oil formation, it is unreactive. Because of its density and low viscosity it is also easily recovered. A saturated solution, containing about 70% cesium formate, sells for ~$6,000/barrel, so yeah, you want to recover it.

“And if it’s true that plastic is not degradable, well, the planet will simply incorporate plastic into a new paradigm: the earth plus plastic. The earth doesn’t share our prejudice toward plastic. Plastic came out of the earth. The earth probably sees plastic as just another one of its children. Could be the only reason the earth allowed us to be spawned from it in the first place. It wanted plastic for itself. Didn’t know how to make it. Needed us. Could be the answer to our age-old egocentric philosophical question, “Why are we here?” “Plastic… asshole.” -George Carlin

The local boffins stopped publishing the data, because it directly conflicted with the story the dirty bloody Greenies were trying to sell that it was Recreational Anglers killing them with boats.

The majority of plastic floats on the surface so your calculation of 200g plastic per billion tonnes of water may be a tad misleading. Perhaps an area calculation is more appropriate.
In any event, I have no problems with floating plastic as it provides a habitat and shelter for many species – not unlike natural rafts of pumice and volcanic ash which can form thick floating ‘Islands’ many kilometres across.

Reply to  'Ash'en Lank
December 11, 2014 1:16 am

Maybe thats the answer – we need to add something to the plastic to make it heavier.
Normally this is done by adding analogues of carbon. For example, the analogue chosen for making venetian blinds heavy is (or used to be) lead – chemically lead resembles carbon in many respects, it can participate in many of the same chemical reactions, which is maybe part of the reason why lead is so horribly toxic.
There are other alternatives, such as silicon – oh dang, lets just use glass… 🙂

In 20 years of sailing the oceans I didn’t find plastic to be much of an issue except near large cities in the developing world. Lots of third world countries dump plastic in the ocean and wait for the tides to take it away.
New years day on Phi Phi Island, Thailand some years back the harbor was full of thousands of floating black plastic garbage bags from the early morning cleanup. We were at anchor and could almost walk to shore on the bags they were that thick.
Nylon is heavier than sea water and normally sinks to the bottom. Poly is lighter than sea water and floats.
nylon nets and lines will sink to the bottom unless buoyed by floats. Poly floats on the surface until enough life grows on it to sink to the bottom, or until it washes ashore.
Sunlight breaks down poly fairly rapidly, but UV resistance can be improved through additives (black poly typically last longer than yellow). nylon is resistant to UV.
Floating poly is an advantage if you are anchoring in coral. It will float free, while nylon will sink and chafe until it fails. Pure chain will wrap itself around the coral as the boat shift on the tide, ever shorting until either the boat is pulled under or the chain breaks. So a poly rode with a chain head is preferred. A float (use an inflated fender) at the chain/poly junction will float the end of the chain above the coral, so the poly doesn’t chafe.
Black plastic bags are a real menace in SE Asia. They float just under the surface and get wound around propeller shafts, working their way past the seals and gumming up the shaft bearings, overloading the engine. The problem can be hard to find.

Well adding weight needlessly to plastics, simply increases shipping costs in all kinds of ways. Cardboard boxes for shipping heavier items need to be reinforced, further increasing the shipping costs and also the tonnage of stuff that needs recycling.
Increasing the weight of something is almost never a productive idea.
But the packaging of consumer and consumable products is a way overbloated industry anyway.
My wife sometimes pays over $32 per gallon for drinking water, which she gets in little 4 or 6 ounce plastic bottles. And they say gasoline is expensive.
The bubble package is one of the dumbest inventions of a supermarket trained naked ape.
My local “green” supermarket, that prides itself in its greenness, and charges more than double the price for some stuff such as “organic” brown eggs, which my wife thinks are great. Eggs are white and yellow and come in an almost hermetic package, that doesn’t get sprayed on.
And if you buy the pricy “organic” milk, you can then walk over to the opposite corner of the green store, and purchase every imaginable chemical additive that you want to add to your organic foods, including 57 varieties of Omega 3 / 6 fish oils, that come from grinding up the krill that whales want to eat or all the menhaden or sardines, that game (food) fishes eat.
Any wonder the sea is losing its food fish, when all the bait species are being slaughtered for yuppie food additive chemicals. I believe you can buy chemical food additives in our green store that start with every letter of the alphabet from A to Z, and then a bunch of Greek ones also.
But the locals who frequent the place are deserving of being fleeced anyway. They are the ones who vote for the duffers who run California.
But I’m with Willis. Never toss anything plastic into the ocean. The rule I like to use on adding stuff to the ocean is very simple and understandable.
Don’t put anything in the ocean until after you have eaten it. (or drunk it).

Since barnacles and other marine life eventually weight the floating plastic down to the point that it sinks and some percentage eventually washes ashore, I imagine the real answer is somewhere between your two calculations. It depends on whether the estimates given were for the total amount of plastic ever dumped into the oceans or the amount currently floating. I’m guessing it is for the total amount ever dumped. For that case we would need to know the half-life of the plastic. That should be the the amount of time needed for half of it to leave the near surface sink to the bottom or was ashore.
Looking at the picture provided and sailing a few years in the N.W. Caribbean where an awful lot is dumped daily, I would bet the half-life to be somewhere between 2 and 5 years.

You could do yourself a service by reading the study Willis:
“However, we stress that our estimates are highly conservative, and may be considered minimum estimates. Our estimates of macroplastic are based on a limited inventory of ocean observations, and would be vastly improved with standardization of methods and more observations. They also do not account for the potentially massive amount of plastic present on shorelines, on the seabed, suspended in the water column, and within organisms.”
You didn’t even read the title:
“Plastic Pollution in the World’s Oceans: More than 5 Trillion Plastic Pieces Weighing over 250,000 Tons Afloat at Sea”
Afloat Willis. Afloat.
Your calculation is just wrong. Correct it.
Perhaps traction is not for you.

December 11, 2014 12:24 am

“Per cubic km of the ocean” seems like the wrong measurement, since plastic tends to remain near the surface of the ocean. Wouldn’t it be more accurate only to count surface water?
Also, plastics break down into smaller and smaller pieces basically forever, so it seems reasonable that all plastic in the ocean will eventually become food, not substrate.

I don’t want to diminish the problem and don’t like poor stewardship of resources. But I’ve always wondered about the consensus question. If plastic were CO2 and sea level were temperature, I’m sure you could find 97% or more of scientists responding to a carefully crafted poll somewhere to agree that mankind via hydrocarbon via plastics is causing sea level to rise, and I’m sure someone could put spin on it to raise taxes or other costs to the public.

According to the NOAA website there is about 20,000,000,000 Kg of Gold dissolved in the Ocean, so it would seem that our Gold pollution problem is more pressing than our plastic pollution problem. Frankly, removing all that gold seems the more attractive prospect because … gold.

Removing all that gold from the ocean is a dumb idea.
Gold, (the riches of the Americas) caused the first period of runaway inflation in history, in the Elizabethan 1500s.
Spanish pirate plundered the Americas, and carted all that useless metal (almost, back then) off to Europe, where people were too busy getting drunk on wine, to bother producing anything of value (consumer goods), so the price of everything went up to absorb all the cash floating around.
The consumer price index went up by a factor of 6 in about 75 years, and then leveled off.
England escaped that inflation, because Queen Elizabeth I met the English pirates at the docks, and confiscated what they had stolen off the Spanish pirates, and she threw it all in the Royal coffers. Basically used it to buy the British Empire.
After that, the CPI stayed level at the new 6X level until the USA went off the gold standard in the 1930s. Then it started on a new inflationary ramp at about the same growth rate as in the 1500s, and we have been on that ramp ever since, as governments all around the world try to outdo each other in printing money, without making anything more to buy with it.
So leave all that useless gold in the ocean where it belongs; we have no good use for it, other than making more Italian Gold chains to wear around our necks.
Mr. T would drown in a flash if he actually went and jumped into the ocean. but that would return some gold to where it properly belongs.
I’m with the Rhine Maidens on that; leave the gold in the water.

I’m not a big proponent of Wikipedia – however for a simplistic explanation here – its worthwhile. Willis is even more right than he states:
“The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean located roughly between 135°W to 155°W and 35°N and 42°N.[1] The patch extends over an indeterminate area, with estimates ranging very widely depending on the degree of plastic concentration used to define the affected area.
The patch is characterized by exceptionally high relative concentrations of pelagic plastics, chemical sludge and other debris that have been trapped by the currents of the North Pacific Gyre.[2] Despite its enormous size and density (4 particles per cubic meter), the patch is not visible from satellite photography, nor is it necessarily detectable to casual boaters or divers in the area, as it consists primarily of a small increase in suspended, often microscopic particles in the upper water column.”
Not typically visible to even boaters in the area … consists mostly of a small increase in suspended microscopic particles. While there are areas of visible debris they tend to be exception not the rule.
Certain weather patterns are conducive to breaking off larger more durable debris at times, which is why for example the Hawaiian island of Kauai at times see ocean debris wash on shore. In particular highly coveted Japanese glass fishing floats (and at times bottles) – some of which have been at sea for decades.

As for the point about radiation back in the days of the protests at Greenham Common someone said they had a list of “military establishments” that had high incidents of some types of cancer.

People have asked here about surface area and plastic so I’ve done a few calculations as I wondered about it myself.
Using the following figures:
– standard grocery bag at 5.5g area 30cm by 50cm when laid out flat
– Worlds Oceans 335,258,000 km2
I calculate that the 270E6 kg of plastic equates to 7,364km2 of plastic in the oceans which is approx. 22m2 plastic per km2 of ocean (or 0.0022% area coverage).
However, not all plastic as the surface area to mass of a grocery bag as thicker things like ropes and plastic parts would be much less.
In reality, due to some plastic sinking and lower surface area/weight plastic parts the figure is much lower than 22m2 per km2 of ocean and is probably much lower than 10m2 per km2. Still something of a pollution problem but helps to put a feel on the figures.
I’m open to correction on my figures as I’ve done them quickly.

You are right to put these figures in context. When put in their proper context, they are frequently so trivial that it becomes extraordinary that there is any significant concern.
The ‘greens’ automatic reaction that anything manmade in the oceans is bad. Sometimes that will be the case, but often it will not. They frequently protest about the sinking of oil rigs or wrecks, and yet the evidence is that these assist biodiversity, and provide useful habitat for many living organismsa nd life forms.

Well jolly, the articles you cite about the “ice wall” are actually about the trenches, a completely different issue. The ice wall is technology that has been used before (although not specifically for radioactive contamination). Without it many tunnelling projects, like Boston’s “Big Dig”, would have been much more difficult.
As for the USS Reagan, they got exposed to less radiation than the flight crew on a trans-Pacidic passenger plane. And citing enenews is a joke right?
The issue is the failed effort to stop the flow of contaminated water. No ice wall has been established at Fukushima Daiichi.

Never said they wouldn’t. But getting your day in court and winning are two totally different things. You see over the last 100+ years scientists have done a lot of research into radiation and have a pretty good handle on what levels are safe and on what illnesses it can cause. The Reagan was exposed to levels well below the point where illnesses occur and the illnesses reported are almost all known not to be caused by radiation.
Add in the fact that the people of Fukushima prefecture, who were exposed to the same radiation at much higher levels and for a much longer time are not reporting such illnesses. They have an almost insurmountable hurdle to clear.
Oh, I expect if it goes to a jury they might initially win on a sympathy vote, but on appeal they will lose.

Hi Willis,
Whilst I’m certainly no fan of the Guardian, could you clarify your calculation of weight of plastic per volume of sea water. Are the volume figures for the whole extent of the Earth’s oceans. If so that supposes that the plastic is uniformly distributed at all depths. Is this the case or is a greater proportion found near the surface. Whichever way I agree there’s too much of it.

I am fortunate to live in a beach front property. As is my wont I walk the beach most days to enjoy the scenery, for exercise and to keep the beach clean of discarded detritus arising from careless human activity. There is simply no excuse for humanity to treat the ocean as a garbage disposal unit – whether the density of this garbage is measured by area or by volume. Whenever I come across a cluster of plastic bags, soft drink bottles, tooth brushes or Coke bottle tops and so on, I ask myself what kind of mother raised the source litterers up? You don’t have to be a rabid ‘greenie’ to show respect for the environment, especially those areas that are community commons, such as are our oceans. Making excuses for plain bad behavior by claiming plastic can provide habitat for some marine organisms, is akin to justifying rubbish accumulating in a person’s back yard, because it provides a habitat for rats.

Generally they follow two themes – “my” patch of beach is as clean as any they have walked on and usually they also comment that they wish they could say the same for beaches in their own country. Now I’m no angel, but if you see willfully disposed beach detritus as a minor annoyance, then I would respectfully disagree with you.

It is correct to present the plastic concentration as only being in a limited section of the ocean – probably the top 30 ft or so. Because the paper explicitly only refers to that area – since it was the only area sampled.
But I am much more interested in the points the paper makes.
1 – it uses models which it claims are conservative. We have heard this before.
2 – it’s major point is that plastic seems to be vanishing! They say that they estimate “233,400 tons of larger plastic items are afloat in the world’s oceans compared to 35,540 tons of microplastics.” This means that there is a fair amount of big stuff, but it doesn’t seem to degrade into little bits which spread around the surface waters. It goes somewhere else – eaten by bacteria or lodged in sediment, perhaps.
This latter point is the main finding, and the one which really could do with more research. In the meantime, it looks as if the ecological concerns that we will be swamped in plastic are misplaced – the stuff does degrade, and then disappears…

Along a narrow road down an abandoned railroad grade about 20 miles northwest of Bemidji, a world-class outdoor laboratory lies among the pine trees.
In part, it marks the spot where on Aug. 20, 1979, a Lakehead Company pipeline seam split, spewing about 440,000 gallons of crude oil. It was one of the largest pipeline spills in Minnesota.
Today, the site is one of the most-studied crude oil spills in the world, and after three decades of research, it still produces important findings.
Scientists here discovered that bacteria that break down oil are everywhere, ready to go to work. Even in the northern Minnesota woods there are microbes that eat carbon and break down oil. The population of those bugs explodes when there’s oil in the ground.
“These microbes are there in very small quantities until ‘whoa, let’s have a party, we have food, we have carbon to eat,'” said Jared Trost, a hydrologist with the U.S. Geological Survey who helps manage the site.
What does every have against these carbon eating microbes?

For perspective … the US EPA estimates that “In 2012, Americans generated about 251 million tons of trash … ”
Are the oceans half empty or half full? If we assume that plastic doesn’t degrade and is therefore “for ever,” then the headline 279,000,000 kilograms of plastic is the total of all plastic released into the oceans since plastic was invented. I’d say that the oceans are much less than half full.
One of the miracles of living in a prosperous country is that every week I fill a large plastic container with stuff I don’t want any more and our municipal waste system takes it away and disposes of it. Safely. Scientifically. To the health and betterment of the citizenry.

December 11, 2014 4:04 am

My first question would be On what basic assumptions has that 270 million kilograms estimate of plastic in the ocean been based?
What verified and researched data source is that estimate based?
Or is it just another of those wild assed enviro green blob guesses doubled to make it look really bad, plastic is after all another nefarious fossil fuel based invention of the human species, plus an additional 80% allowance included to cover any possibility of someone suggesting that the plastic problem is of very minor consequence in the total scheme of ocean area and volume.
And it seems it might be just that as ocean life in all it’s immense diversity gets a taste for those hydro carbon based plastics.
We always without fail, badly underestimate the ability of life and Nature to adapt to just about any circumstance and to adapt to and use whatever is available to support life in all it’s uncountable myriad forms.
[ global warning catastrophists please note the above comment ]
The plastic / bio-organisms / sea life interaction has already been the subject of a couple of quite recent studies, one from the University of Western Australia and another from MIT and the Woods Hole Oceanographic Institute;
Quoted from the MIT / WHOI study abstract;
“Ocean Plastics Host Surprising Microbial Array”
Abstract selections;
But much still remains unknown about the ecological impacts of these materials. So a group of Massachusetts researchers, led by Linda A. Amaral-Zettler at the Marine Biological Laboratory and Tracy J. Mincer at Woods Hole Oceanographic Institution, decided to study the microbial communities found on plastics to explore how the organisms affect marine environments.
The team analyzed plastic samples they collected during two research cruises to the North Atlantic Subtropical Gyre, a stretch of ocean roughly midway between the eastern coast of North America and Africa. They used a scanning electron microscope, among other techniques, to study the bacteria living on the particles. “What we found really blew us across the room,” says Mincer, a microbial ecologist:
They couldn’t say for sure, but the bacteria appeared to burrow pits into the plastic, which had never been observed before. The team didn’t expect such behavior, because they thought nutrient levels in that region wouldn’t support bacteria digesting hydrocarbons in this way.
The group suspects this may at least partially explain a surprising aspect of plastic waste found in previous studies in this region of the Atlantic. Even though the amount of plastic waste entering the ocean is probably increasing, researchers at Sea Education Association, a nonprofit group that studies the ocean environment, have not found an increase in plastics in the sea (Science 2010, DOI: 10.1126/science.1192321).
Mincer says one possible explanation is that bacteria eat into the polymers, weakening the pieces enough to cause them to break down more quickly and eventually sink to the sea floor. Supporting this hypothesis, some of the plastic-burrowing bacteria are closely related to species known to consume other types of hydrocarbons, such as oil.
Because of the possible risks the debris poses to marine life, microbes breaking down plastic pollution would be a promising discovery, says Michael Cunliffe, a marine microbiologist at the Marine Biological Association of the United Kingdom. “But it needs to be shown in a bit more detail.”
Besides the bacterial pits, the team also found evidence that the microbial communities on plastics were distinct from those found in surrounding waters. A single sample a few centimeters across could contain hundreds of microbial species. “It’s really like a microbial reef,” Mincer says.

“Millimeter-Sized Marine Plastics: A New Pelagic Habitat for Microorganisms and Invertebrates”
Selected Abstract quotes
Millimeter-sized plastics are abundant in most marine surface waters, and known to carry fouling organisms that potentially play key roles in the fate and ecological impacts of plastic pollution. In this study we used scanning electron microscopy to characterize biodiversity of organisms on the surface of 68 small floating plastics (length range = 1.7–24.3 mm, median = 3.2 mm) from Australia-wide coastal and oceanic, tropical to temperate sample collections. Diatoms were the most diverse group of plastic colonizers, represented by 14 genera. We also recorded ‘epiplastic’ coccolithophores (7 genera), bryozoans, barnacles (Lepas spp.), a dinoflagellate (Ceratium), an isopod (Asellota), a marine worm, marine insect eggs (Halobates sp.), as well as rounded, elongated, and spiral cells putatively identified as bacteria, cyanobacteria, and fungi. Furthermore, we observed a variety of plastic surface microtextures, including pits and grooves conforming to the shape of microorganisms, suggesting that biota may play an important role in plastic degradation. This study highlights how anthropogenic millimeter-sized polymers have created a new pelagic habitat for microorganisms and invertebrates. The ecological ramifications of this phenomenon for marine organism dispersal, ocean productivity, and biotransfer of plastic-associated pollutants, remains to be elucidated.

And the abstract from the Sea Education Association’s 22 year long, from 1986 to 2008, research project on plastic accumulation referred to in the MIT paper above;
“Plastic accumulation in the North Atlantic subtropical gyre”.
Plastic marine pollution is a major environmental concern, yet a quantitative description of the scope of this problem in the open ocean is lacking. Here, we present a time series of plastic content at the surface of the western North Atlantic Ocean and Caribbean Sea from 1986 to 2008. More than 60% of 6136 surface plankton net tows collected buoyant plastic pieces, typically millimeters in size. The highest concentration of plastic debris was observed in subtropical latitudes and associated with the observed large-scale convergence in surface currents predicted by Ekman dynamics.
Despite a rapid increase in plastic production and disposal during this time period, no trend in plastic concentration was observed in the region of highest accumulation.

“…270,000,000 kilograms of plastic works out to 200 grams of plastic per cubic kilometer of the ocean.”
That would be correct if the plastic were uniformly distributed. But most of it likely floating on the surface or sunk to the bottom. And the floating stuff mostly likely collects in clumps in much smaller regions, determined by ocean winds and currents. So I’m guessing there is generally a famine of plastic throughout the oceans, with regional areas where it collects in abundance.

When presented with statistics in a discussion I always ask, “What if I told you I could double your chances of winning the lottery immediately?” They become quiet at that thought, and I tell them to buy 2 lottery tickets instead of 1. Somehow having a 2 in a 5 million chance of winning over a 1 in a 5 million chance does not match the promise of doubling your chances.
The issue is context. The same game is played with cigarette smoking, as in the lottery example, the likely hood of getting lung cancer is without question increased with smoking, but I believe people need to know what those risks are in context. Why isn’t it communicated simply: smokers chance of lung cancer is x in 100,000 while a non-smoker is x per 100,000. What about explaining the vast majority of lung cancer deaths occur after age 70 where there are a whole host of other afflictions that kill people after that age?
I myself am pretty tired of being in an age where fear mongering is the primary method of institutions communicating to the public. Doesn’t sound like an enlightened age, more like medieval.

But, since lottery numbers are randomly generated, if you bought all of the tickets printed you still wouldn’t be guaranteed of winning. And, because the Government always takes a free slice or two, even if you did win, the payoff would be less than total ticket cost.
So buying two tickets just increases your chance of losing. Slightly. 🙂

Lung cancer is just one of many potential health penalties associated with smoking.
From the CDC:

Harms nearly every organ of the body
Causes many diseases and reduces the health of smokers in general

The immune system is the body’s way of protecting itself from infection and disease. Smoking compromises the immune system, making smokers more likely to have respiratory infections.
Smoking also causes several autoimmune diseases, including Crohn’s disease and rheumatoid arthritis. It may also play a role in periodic flare-ups of signs and symptoms of autoimmune diseases. Smoking doubles your risk of developing rheumatoid arthritis.
Smoking has recently been linked to type 2 diabetes, also known as adult-onset diabetes. Smokers are 30% to 40% more likely to develop type 2 diabetes than nonsmokers. Additionally, the more cigarettes an individual smokes, the higher the risk for diabetes.
Recent studies show a direct relationship between tobacco use and decreased bone density
The chemicals in tobacco smoke harm your blood cells and damage the function of your heart. This damage increases your risk for:
Atherosclerosis, a disease in which a waxy substance called plaque builds up in your arteries
Aneurysms, which are bulging blood vessels that can burst and cause death
Cardiovascular disease (CVD), which includes:
Coronary heart disease (CHD), narrow or blocked arteries around the heart
Heart attack and damage to your arteries
Heart-related chest pain
High blood pressure
Coronary Heart disease, where platelets—components in the blood—stick together along with proteins for form clots which can then get stuck in the plaque in the walls of arteries and cause heart attacks
Peripheral arterial disease (PAD), a condition in which plaque builds up in the arteries that carry blood to the head, organs, and limbs
Stroke, which is sudden death of brain cells caused by blood clots or bleeding
Breathing tobacco smoke can even change your blood chemistry and damage your blood vessels. As you inhale smoke, cells that line your body’s blood vessels react to its chemicals. Your heart rate and blood pressure go up and your blood vessels thicken and narrow.

We are awash in this nonsense and I believe the greens and newspaper supporters are counterproductive to their cause in turning so much of this stuff out.
One of the main things that all this hype has polluted is the internet. Type in the word asbestos. If you are hoping to find a lot of articles on the mineralogy and mining of it, you are out of luck. It was another over-hyped topic some 40 years ago and it hasn’t abated much with time. It was taken out of asbetos-cement pipe for conducting potable water, even though there was more abestos and abestos-form mineral concentration in natural river waters in the Canadian north where it was derived from the metamorphosed rock formations of the Canadian Shield. I drank lots of it over many decades. Here is an EPA report on filteriing asbestiform particles out of Lake Superior water (I hate these long links).\zyfiles\Index%20Data\70thru75\Txt0000001\2000FXPU.txt&User=ANONYMOUS&Password=anonymous&SortMethod=h|-&MaximumDocuments=1&FuzzyDegree=0&ImageQuality=r75g8/r75g8/x150y150g16/i425&Display=p|f&DefSeekPage=x&SearchBack=ZyActionL&Back=ZyActionS&BackDesc=Results%20page&MaximumPages=1&ZyEntry=1&SeekPage=x&ZyPURL

If it is a hollow fibre asbestos. If the fibre is hollow it allows a lot of biological things to happen protected from the immune system. Cancers are one of the possible results. Asbestos comes in many different types and chemical formulations. The good have been cursed by the bad due to the same name.

As someone posted above, it would be nice if some of the $ wasted on fictitious CAGW could be directed to cleaning up the mess.
Some species like the laysan albatross use natural plastics as part of their diet and isn’t necessarily harmful, although it would be so much better if the US and other nations didn’t use our oceans as a dumping ground.
This article is in Living Bird magazine by Cornell Lab of Ornithology and their blog.
“They don’t eat plastics by mistake,” Flint said, “They seek them out and swallow them on purpose because they’re a substrate for flying fish eggs. If you walked around an albatross colony in the 1950s, you would find albatross carcasses full of pumice and sticks and wood.
“They’ve been eating natural plastics all their life,” she said, referring to the hard, sharp beaks of squid that are the albatrosses’ main food. Flint stressed that plastics do pose problems: they harm species lower on the food chain. They also accumulate toxins from the water and can pose a chemical threat when swallowed. But they do not necessarily cause albatross chicks to starve. Before fledging, most albatross chicks cough up plastic and squid beaks alike to clear their stomach before taking their first flight. Kaloakulua successfully regurgitated her “bolus” of stomach contents on June 1, 2014. The following video shows a Kauai Albatross Network volunteer examining the plastic that it contained:

December 11, 2014 6:46 am

Part of the issue with all the plastic pollution in the oceans is the fact that it is washing up on the shores of Pacific islands like Midway Atoll in the northwest Hawaiian islands chain. Midway was closed down as a U.S. naval base some years ago and is now a federal wildlife refuge.
The problem according to reports and the images below is that the bird life on these islands mistake the small plastic pieces for food and consume them. Their digestive systems cannot handle the digestion of the plastic and it ends up killing them.
I am making no claim here regarding the legitimacy of these reports or the seriousness of the problem, and many of the images above do appear to show plastic pieces having been placed on the bird carcass before the photos were taken. As a animal lover however it is disturbing to see those photos of dead birds, and keeping the shores of Midway and the rest of the Northwest Hawaiian Islands (which are all wildlife refuges) free of the plastic is a never-ending chore. According to reports, much if not most of the plastic is actually coming from Japan rather than the U.S.
Just wanted to make everyone aware.

Good points. An aside: Many birds seek out strange stuff to consume as part of their natural process of digestion and ridding their guts of indigestible bits like bones, squid beaks, etc. Owls and other raptors routinely cough up ‘pellets’ and many birds consume grit, pebbles and even stones to help the digestion process. Yes, have to be careful regarding some photos, especially from sites that have an agenda or axe to grind.

I heard an interesting radio interview several months ago, and apparently there is an issue with the presence of microplastics collecting on the ocean floor – the reason being that they are ingested by both small and large marine organisms, and have been shown to concentrate toxic chemicals that are already present in sea water. These microplastics get there in a variety of ways – microbeads in cosmetics, plastic bags that fragment instead of degrading, even washing our polyester-containing clothes (microscopic lint is shed from the clothing into the waste water and eventually ends up in the ocean). Tiny organisms ingest these bits of plastic, bigger organisms eat them – and so on. Currently, the cumulative effects are not known, although they are being studied.

Pure conjecture and exaggerated hype from the eco-greenery culture – that wants more money, and feeds internally off of fear and projections. For example, these critters are supposedly getting harmed by sub-microscopic “dirt” – that is “articificial dirt” and grit really – when they LIVE ON the muck, sand, grit, and soil erosion and billions of tons of organic residue drifting down over the waters from above? The “muck” dropped down to the bottom by the time the ocean floor reaches the continental shelves is thousands and thousands of meters deep. And that is where these bottom-feeders live!
But “artificial plastics” are supposedly building up and harming them? What? They have never heard of pearls before? Of sperm whales’ coating squid beaks? Of fish swallowing fish whole – then “fish poop” falling below?

We can argue about how important it is till the cows come home but the simple fact is that nowhere on this earth is there a truly pristine beach. And it is one thing to show a pic of plastic in an Albatross carcass. It is another to watch those birds die a horrible death. “Goony birds” is what the sailors on Midway during WW II called them. The birds were unafraid of man even when that atoll was covered with people and aircraft. A person could walk up to one and help launch it into the wind. Now Midway is a trash heap.
On Betio Island of the Tarawa atoll fragments of bones of marines that fought and were blown to pieces there in that concentrated hell are found among the piles of trash and plastic on the beaches to this day. Portions of the beaches where so many died taking the most concentrated defense the fanatical Japanese would mount during the whole war are nothing more than trash heaps.
I could go on with other examples but I think you now get where I stand on this issue.

December 11, 2014 8:46 am

Thank you, Willis. Your perspective is always helpful. Despite that analysis, I still worry about two aspects of the ocean-borne plastic problem.
The first is microparticles. Much of the plastic in the ocean is not the big, still-identifiable styrofoam cups and water bottles – it is plastic that has been ground down to the size of dust. Permit a short analogy – there is a great deal of dirt on the land. I don’t worry about any of it, however, because only the small fraction that’s of the right size to stay airborne will affect my asthma. That fraction, however, affects me very much. And it doesn’t take very much per km3 of atmosphere to keep me indoors.
My second remaining concern is the unstated assumption that the plastic is and remains biologically inert. If, as some research as suggested, plastic can decompose into hormone-like compounds, it again could have effect disproportionate to its apparent quantity. (My hypothesis, by the way, would be that such breakdown components would disperse more easily than the original solid plastic artifacts and that therefore any hormonal effects could be felt even in areas with no apparent solid pollution.)

December 11, 2014 8:50 am

However, as an ocean problem, it’s way, way below things like overfishing and pollution.

And what type of emissions should count as pollution?
It cannot be sewage, that is after all just plant food, like CO2. The main ingredients in sewage are Nitrogen and Phosphorous which is also the main ingredients in fertilizers. Acid rain contains SO2, i.e. Sulfur which is another ingredient in fertilizer.
Is it only heavy metals that counts as pollutants? Most of the heavy metal pollution comes from burning of coal by the way.

Jan, always a bit sketchy to generalize to something as large and biodiverse as the oceans. One example. Sewage ( and more generally organic runoff) is a major ‘pollutant’ of coastal coral reefs. As the prganic matter decomposes, it gives off trace hydrogen sulfide (swamp gas) whichnis an acute toxin to marine organisms in the same way and formthemsame reasons that cyanide is for humans. The LD50 of H2S for corals, crabs, and such is about 30 PPB!
Acid rain is a problem for fresh water lakes in metamorphic or igneous geologies where there is no carbonate for neutralization, like New England. Ocean dissolved carbonate neutralizes it, so not a big ocean concern. And so on.
Cost/benefit analyses need to be reasonably granular to be meaningful.

December 11, 2014 9:40 am

Is ocean plastic really “forever” or just food for a yet-to-evolve bacteria?

Rud Istvan
December 11, 2014 9:55 am

Three observations. First, Willis’ post is a good example of the need for information perspective, a topic explored in that chapter of The Arts of Truth. Much of the current media commentary about ‘shale oil’ and the Saudi ‘price war’ on it suffers from lack of perspective (as well as lack of Petroleum 101 geophysics).
Second, the plastics estimate. Never trust media (especially like Grauniad). The article reports on a new paper in PLOS/1. No paywall, good SI. Really interesting. Result of 14 separate expeditions to all major ocean areas, 680 towed fine mesh (0.3mm) net transects (to depth of 2 meters) and 891 large object visual transect counts by 9 plastic object types. Net samples actually sorted and measured for volume and weight by particle size class. Large visual object samples measures for volume and weight by type class. Massive experimental results fed into US Navy’s world ocean model surface layer for currents and winds to generalize the sampled transects to the globe, producing the generalized 269,000 metric tons estimate. Solid science IMO. Glad Willis brought it to our attention. And showing Willis’ gedanken used a wrong assumption. It should be square km of surface to a depth of two meters, NOT cubic km.
Third, ROM’s comment above identified two very interesting papers on how bacteria and other microorganisms colonize (and at least in some cases consume) the smaller plastic bits. Why is that important? Because it completely explains biologically the biggest surprise finding of the PLOS/1 paper. Actual samples matched the generalized Navy ocean model result really well (statisticly, for all oceans and gyres) for all visual types and all particle sizes (light and wave turbulence plastic degradation) except for the smallest particle class. There, the model produced an order of magnitude more plastic than observed. As the plastic bits get smaller, they get biologically recycled, something the ‘physical’ ocean model did not incorporate.
That good news is something the Grauniad probably would not report, since it means ocean plastic–while not good–is much less alarming than Grauniad implied, for reasons independent of Willis’ quantitative perspective.

Then there is this:
Millions of pounds of unexploded bombs dumped in the Gulf of Mexico by the U.S. government after World War Two pose a significant risk to offshore oil drilling, warn researchers.
It is no secret that the United States, along with other governments, dumped munitions and chemical weapons in oceans from 1946 until the practice was banned in the 1970s by U.S. law and international treaty, said William Bryant, a Texas A&M University professor of oceanography.
Last year, BP shut its key Forties crude pipeline in the North Sea for five days while it removed a 13-foot (4-metre) unexploded German mine found resting cozily next to the pipeline that transports up to 40 percent of the UK’s oil production.
Hundreds of dolphins washed ashore in Virginia and New Jersey shorelines in 1987 with burns similar to mustard gas exposure. One marine-mammal specialist suspects Army-dumped chemical weapons killed them.
“The Army now admits that it secretly dumped 64 million pounds of nerve and mustard agents into the sea, along with 400,000 chemical-filled bombs, land mines and rockets and more than 500 tons of radioactive waste – either tossed overboard or packed into the holds of scuttled vessels.”
Most of the present day ocean trash dumping (much like any other dumping including chemical) is probably done illegally by those just saving a buck, and not particularly caring about any consequences (10 percenter’s).

Need I re-quote George Carlin from the 5 December post here on WUWT?
“And if it’s true that plastic is not degradable, well, the planet will simply incorporate plastic into a new paradigm: the earth plus plastic. The earth doesn’t share our prejudice toward plastic. Plastic came out of the earth. The earth probably sees plastic as just another one of its children. Could be the only reason the earth allowed us to be spawned from it in the first place. It wanted plastic for itself. Didn’t know how to make it. Needed us. Could be the answer to our age-old egocentric philosophical question, “Why are we here?” “Plastic… asshole.” -George Carlin

The consequences of pollution are inevitably measured in context and in proportion to concentration. Even the much maligned oil is a nutrient that feeds the base of some ecosystems.

December 11, 2014 11:17 am

I used a different approach, but obviously came to a similar result. I think using cubic km is a bit over the top. the stuff is ‘floating’ after all. I used cubic meters multiplied by surface area in meters to get the weight of the top meter of ocean.

> Physicist: There was no Fukushima nuclear disaster
That’s true enough. But there is a complex and expensive clean up problem and a displaced population issue that is due to the failure of the facilities at the plant. What bothers me is that it was probably avoidable. When the Fukushima-daiichi plant was designed, it was thought (incorrectly) that the largest likely earthquake would be about that of the great Kanto earthquake of 1923 that pretty much flattened the Tokyo-Yokohama area — magnitude 7.9. That’s what Fukushima was designed for and AFAICS, it’d probably have handled a magnitude 8.0 quake and the associated tsunami without problem.
But by 1985 at the latest, it had become clear that substantially stronger quakes were possible at the plate boundaries off the coast of Honshu. The Fukushima facility was never upgraded to reflect that knowledge. Would an upgrade have prevented all damage to the plant? I have no idea. But I think it would have probably helped a lot.

The displaced population is mostly because of rabid radiophobia, most of the evacuated areas did not need to be evacuated.

Dunno ’bout that.
There are reports that unit 1 was smoking already before the tsunami hit, and radiation alarms were going off, according to documents supplied by TEPCO.

TOKYO: A radiation alarm went off at the Fukushima nuclear power plant before the tsunami hit on March 11, suggesting that contrary to earlier assumptions the reactors were damaged by the earthquake that spawned the wall of water.
A monitoring post on the perimeter of the plant went off at 3.29pm, minutes before the station was overwhelmed by water, knocking out the back-up power that kept cooling systems running, according to documents supplied by the Tokyo Electric Power Company (Tepco).
More here includes worker reports of buckling, bursting pipes prior to tsunami:

A second worker, a technician in his late 30s, who was also on site at the time of the earthquake, narrated what happened. “It felt like the earthquake hit in two waves, the first impact was so intense you could see the building shaking, the pipes buckling, and within minutes, I saw pipes bursting. Some fell off the wall. Others snapped.

“Does it look like a) that chunk of plastic is inimical to sea life … or does it look like b) that chunk of plastic is acting a substrate upon which abundant sea life is living and serving as fish food? Call me crazy but I’m going for Choice b), you can see the little striped fish chowing down. Now I know that not all plastic is good for sea life … but that plastic certainly is.”
“Now, I’m willing to agree that there are some kinds of plastic that are likely inimical to sealife. Nylon fishing nets that have been lost and gone adrift, for example, continue to kill fish.”
Go to the Guardian story and you can get a higher res version of the picture. That chunk of plastic that is “is acting a substrate upon which abundant sea life is living and serving as fish food” very much appears to be a fragment of nylon fishing net, so your comment that “Nylon fishing nets that have been lost and gone adrift, for example, continue to kill fish.” is clearly not universally true.

Plastic in the ocean is as distressing as any trash you see laying about. For poor societies the oceans are a cost effective method of disposal. Only wealthy societies can afford recycling and proper disposal of waste. If the greens have their way, hindering prosperity in the poorer parts of the world, we’ll never see cleaner oceans.

So, some patches of flotsam have been found in the Horse Latitudes, exactly where you would expect such patches. So, based on such encounters, someone concluded that the Horse Latitudes have some ungodly amount of flotsam, essentially an extrapolation. I seriously doubt anyone has mapped this explicitly and done an all inclusive survey. No one really knows how much flotsam is really out there and even “pure research” orgs need to allocate their vessels and satellites for higher priority tasks.

Just for the heck of it.
Its probably in the Granuid but I haven’t seen it reported anywhere as yet until this morning’s ” Australian” [ Fri 12th Dec. ]
The “Guardian’s” Alan Rushburger News and Media Editor for the last 20 years will step down to become the Guardian’s funder, “The Scott Trust ” Chairman.
Globally The Guardian posted a loss of 30.6 million pounds for the year ending March 30th. [AUD $57.8 million ]
Guardian Australia posted a loss of $7.5 million loss on sales revenues of $3.79 million;
Editors in chief aren’t exactly renown for their reticence in making a personal impact when and where at all possible.
A new editor invariably likes to shift a lot of things around in any news sheet he / she might get the chance to edit.
So we can expect some changes in the Guardians news reporting whether for good or bad or for better or for worse, we will just have to wait and see.
Not that it can get much worse from the Guardian’s present execrable exaggeration of anything that looks like it might arouse a further elevating of emotional environmentalism regardless of the actual facts of the case.

Every two years a research vessel does transects of the Pacific Gyre. First, there is no floating island the size of Rhode Island in the center. There is no island of any size; there simple is no aggregation at all. Second, the most recent such research trip had to trawl for longer than usual to gather enough pieces of plastic to be able to do a statistical treatment. Third, they report that the amount of plastic has been creasing exponentially for decades, dwindling away as countries and ships learn how not to lose their trash in the sea. Fourth, there is an real island in the Pacific gyre that indeed does have plastic on its shores. The plastic is largely little tiny pieces, similar to sand, which means that the plastic is being churned and ground into tiny pieces that degrade that much faster. It is indeed going away.
Years ago, with the invention of formica counter tops, the prediction was that someday we would be drowning in formica waste, as it would not break down. Only two decades later there were at least two strains of fungus that had learned to eat formica. Nature truly does not like to waste a perfectly good food source.
Plastics at sea perform two major functions besides serving as useful habitats for marine life. They can serve as a food source as bacteria and fungi break them down, and some kinds of plastic absorb toxins from the water and are broken down over time by solar light and UV radiation.
I seriously believe that the stated amount of plastic in the paper is a gross over-estimate, as the worst pollution is concentrated near the shorelines of undeveloped countries. I am also sure that the estimate required some rampant extrapolation, which would be perfectly in keeping with such alarmist material. It is unlikely to be an under-estimate; what would be the alarm in that?

“because it turns out that the 270,000,000 kilograms of plastic works out to 200 grams of plastic per cubic kilometer of the ocean. Or in old-school measurements, that’s just under two pounds of plastic per cubic mile of seawater.”
I assume that most of the plastic is less dense than water since an annoying amount seems to end up littering beaches, and really dense material is surely going to end up on the bottom. So I think probably we should be talking in terms of plastic per unit area, not volume. That would be 270,000 metric tonnes distributed over 361 million square kilometers of ocean surface or about 748 grams per square kilometer. Or about 1.65lb per square kilometer. Is that annoying? It annoys me and probably most readers. Is it a matter for real concern? Probably not. Are we all going to die because of it? I doubt it.

I recall a conversation with a Green friend who waxed animated about “Garbage Island” in the Pacific. I asked him why we never see a photograph of Garbage Island, and ventured the opinion that it was probably not actually an island in the sense of being something you could stand on, or even see. He told me I was quite wrong. I suggested we google to settle the matter. After we did so, he was gracious enough to admit I was right.

If it was not for the CO2 religion this would not be an issue. A small firm near here produces a plasma furnace that burns the stuff producing no toxins. I looked at their data and found that a ship could harvest the stuff totally self powered from what it collects and have 80% left over for base station combustion based on the density quoted at the collection areas divided by ten for greenwashing of the image of industry and exaggeration of fossil fuel problems.

December 12, 2014 3:45 pm

Large holes in your logic. First, small ingestible plastic is the biggest issue. I would give a three year old a plastic bottle but only with out the cap. Only talking about large pieces is somewhat of a straw man argument.
Second, how many cubic meters of sea water goes through a fish’s gills in its lifetime? This narrows the numbers. Not necessarily the conclusion.

Because you refer to plastic that is large enough for organisms to attach to. Are you suggesting it is not a problem for marine animals to ingest nonbiodegrable objects?
“plastic soda rings, “baggies,” styrofoam particles and plastic pellets are often mistaken by sea turtles as authentic food. Clogging their intestines, and missing out on vital nutrients, the turtles starve to death. Seabirds undergo a similar ordeal, mistaking the pellets for fish eggs, small crab and other prey, sometimes even feeding the pellets to their young. Despite the fact that only 0.05% of plastic pieces from surface waters are pellets, they comprise about 70% of the plastic eaten by seabirds. These small plastic particles have been found in the stomachs of 63 of the world’s approximately 250 species of seabirds”
Five minutes on google to validate what my logic.

December 12, 2014 8:01 pm

Um, if I did the math right, that 5 Trillion pieces to make up 270 Billion grams has 270 / 5000 grams per piece. I make that about 5 / 100 or 1/20 gram per piece. We’re talking grit or dust here. On average…

While we are on the subject, it is worth tracing back the source of the original alarmist claims about how plastics in the sea were allegedly wiping out millions of sea dwelling creatures and birds. It is one of the Great Lies which has underpinned spurious bans on plastic shopping bags all over the world.
Google being what (and who) it is, I can’t find the references just now. It is the kind of thing that they put at 3,583 on their list. But, the whole “plastics are murderers” meme was based on a single study of Canadian fishing industry waste products. The researchers extrapolated from bits of nets and other debris of the fishing industry in and around a single site (somewhere around Newfoundland, perhaps, but please correct me) that this represented the whole world.
From then on, this extraordinary upside-down pyramid of bizzare and dopey measures like banning plastic shopping bags was constructed, all over the world.
I have tracked this reference down at least twice before, but stupidly have not saved it. It exists, but this old broad is a bit busy just now. Plus, I can’t believe that it hasn’t already been bannered all over the sceptic blogs, which seem to be more interested in arcania than common sense a lot of the time.
As Willis has pointed out, there is no “island of plastic.” I cannot tell you how many times, when presented with this absurd proposition, I have asked for things like photographs or other evidence, and been excoriated for it.
Willis, if you have time, trace back the whole history of murderous plastic in the sea, and domestic shopping bags. It is one of the great unexamined con jobs. It all began (and pretty much ended) with a single study of washed up fishing equipment in Canada decades ago.

Here you go johanna:
“The name “Pacific Garbage Patch” has led many to believe that this area is a large and continuous patch of easily visible marine debris items such as bottles and other litter —akin to a literal island of trash that should be visible with satellite or aerial photographs. While higher concentrations of litter items can be found in this area, along with other debris such as derelict fishing nets, much of the debris is actually small pieces of floating plastic that are not immediately evident to the naked eye.
The debris is continuously mixed by wind and wave action and widely dispersed both over huge surface areas and throughout the top portion of the water column. It is possible to sail through the “garbage patch” area and see very little or no debris on the water’s surface. It is also difficult to estimate the size of these “patches,” because the borders and content constantly change with ocean currents and winds. Regardless of the exact size, mass, and location of the “garbage patch,” manmade debris does not belong in our oceans and waterways and must be addressed.”
source: NOAA; another WUWT poster left the link some time ago.
If shopping bags are banned, this will force people to buy plastic bags to put their trash in.

Thanks, Zeke, but the thing really want to find is the story of the single Canadian study which started the whole thing off. I think it was published in a British newspaper some years ago.
Bottom line is, the entire edifice of “millions of sea critters murdered by plastic every year” was based on one study of fishing gear washed up on the coast somewhere in Canada. To my knowledge, there are absolutely so empirical studies on which to base this claim – just lots of subsequent modelling.

johanna says, “the thing really want to find is the story of the single Canadian study which started the whole thing off.”
Okay I went and checked a couple of off-line sources to help, but plastic is not mentioned specifically in the books I have because they focus on chemicals.
I have found an original MIT paper written for the UN that mention CO2, but they admitted then in the 80’s that there was not enough data to compare past and present. It was a theory without a cause at first; just a ghost suspended with no materiality.
I also found out that the real goal of the “Sustainability” scientific paradigm is not for people to drive electric cars, but “pedal-power.” Lester R Brown, State of the World 1990.

Nope Willis. You have not corrected your big error. Do yourself a service. Read what you have written:
“However, I started out with the question about whether 270,000,000 kilogrammes is a big number or a small number. Looking at the extent of the ocean gives us a very different picture … because it turns out that the 270,000,000 kilograms of plastic works out to 200 grams of plastic per cubic kilometer of the ocean.”
“And as for the other small pieces of random plastic … well, I just can’t get all that passionate about the dangers of 200 grams of plastic for every BILLION tonnes of sea water (1 cubic km = one billion tonnes).”
Not corrected.
Are such errors embarrising for you Willis? Perhaps you are trying to reduce the traction for this blog. And for yourself.
[How are you converting units? One gigatonne is one billion metric tonnes ( 1 Gt = 1 x 10^9 tonnes) .. One gigatonne of water has a volume of one billion cubic meters, or one cubic kilometer. (1 Gt water ≡ 1 km³)”
1 GT = 1 gigaton
= 109 tons (U.S. tons or “short tons,” each 907.185 kg or 2000 lbs)
1 Gt = 1 gigatonne
= 109 tonnes (metric tons, each 1000 kg or 2204.62 lbs)
= 1012 kg
= 1.1023 GT
= the mass of 1 cubic kilometer of fresh water
= the mass of 1.091 cubic km of ice

Willis you state “iron, if you have evidence that the “small ingestible plastic” is a problem in the ocean, then please cite it. As a lifelong sailor, surfer, commercial and sport fisherman, and commercial and sport diver, I’m always willing to learn more about the ocean.
All the best to you,”
So, I did as you asked. And your response you spend several paragraphs arguing with yourself about entanglement? Huh? When you get around to the actual subject.
“Well, it only took me about fifteen minutes to demolish your claims using actual scientific studies rather than the predigested pap that seems to impress you… sorry, but uncited, unsourced articles in the popular press don’t carry any weight here. This is a scientific site, and we’ve seen thousands of false claims in the popular press about a host of subjects. You’re gonna have to up your game, my friend. Don’t get me wrong, I think you can up your game … but so far it’s just empty claims.
And in any case, here you are claiming that your citation backs up your claim about deaths from creatures eating plastic … and other than the problems for turtles, where as I’ve already discussed it causes some deaths, it doesn’t mention even one death from small particles or from birds eating plastic. Not one. Not saying there aren’t any … just saying your citation said nothing about them.”
Apparently, you aren’t really willing to learn more. Just pretend it for a bit until someone challenges you then start in with the attacks. Where the hell did I “claim about deaths from creatures eating plastic” Please site the specific words yada yada. I simply stated logically small ingestible pieces of plastic are more of a concern then larger pieces. I even pointed out the my google search was cursory, but I apparently insulted Mr. know it all and therefore must be raked over the coals so he can show his superior intellect.
Your specious strawman tactics may work for you but they are very pathetic. Let’s look at one.
“it only took me about fifteen minutes to demolish your claims using actual scientific studies”
Please point me to the “actual scientific studies” you mentioned, not new ones, that studied small ingestible plastics, not the strawman entanglement argument you made up. Perhaps you should up your game.
Next up “here you are claiming that your citation backs up your claim about deaths from creatures eating plastic” I never made any such claim. I never claimed the author was right, valid, or etc… I said it backed up my logic, along with the multiple other links that come up when you search google. I even was looking at one link that was a scientific gathering to discuss this issue. You know how to use google, and since you care I am sure you have already done that. You just can’t admit that you may have made a logical error in arguing about entanglement and larger pieces.
Oh and by the way I didn’t know that some .edu site I had never heard of until I did the search was “uncited, unsourced articles in the popular press”, I guess it may be popular and I just don’t know it, but unsourced? there’s this thing at the bottom, I think they call it a link, it says “bibliography”, but hey Mr. Know It All says I’m impressed easily by predigested pap and I don’t have a good game so what do I know.
You seem to think acting childish is upping ones game, so perhaps I can do that too.
You should also note, I never even claimed the conclusion of your article was wrong.
All the best to you

I would imagine bottom feeding fish, would have a system to expel non-digestible sand etc. so plastic should also be expelled. Do you know of any data to suggest that other fish are or are not effected by small plastic pieces? Logically to me this would be a larger problem then large chunks of plastic. A 1kg hunk of plastic in 1km^2 of ocean surface is less concerning then 1000 1gram pieces floating in the same 1km^2 of ocean. This is what I am trying to convey. Do I have data to back it up? No. Logically I can see no reason to assume other wise.
You have already shown why in your opinion why large chunks of plastic are not necessarily a super killer. I tend to agree with your logic on this. I just think we would be intellectually dishonest if we don’t discuss what impact small plastics may have.
You won’t get any argument out of me that almost every problem is overhyped. Which is sad because when real issues arise the reflex is to assume it is overhyped.
Real pollution such as plastic in the ocean sucks. If you are like me there is nothing more disgusting then hiking across a mountain meadow and seeing garbage, or garbage on a beautiful beach. How many superfund sites could have been cleaned up with the billions wasted on AGW.
I honestly don’t think our thinking is that different.

Not sure if would apply to fish, but I had a dog that occasionally would eat pieces of “things” that passed through its digestive system but parts of which were still hanging out of its butt after a poop.
I believed the next digestive movement would have fixed the problem, but the dog wasn’t sure (you could tell by its demeanor, tail down and not its happy self), so I would pull out offending material, and the dog would instantly revert to his happy self.
