Claim: NOAA says the Arctic Ocean is becoming "corrosive"

From NOAA’s department of acidic wordsmithing: New study shows Arctic Ocean rapidly becoming more corrosive to marine species

Chukchi and Beaufort Seas could become less hospitable to shelled animals by 2030

New research by NOAA, University of Alaska, and Woods Hole Oceanographic Institution in the journal Oceanography shows that surface waters of the Chukchi and Beaufort seas could reach levels of acidity that threaten the ability of animals to build and maintain their shells by 2030, with the Bering Sea reaching this level of acidity by 2044.

“Our research shows that within 15 years, the chemistry of these waters may no longer be saturated with enough calcium carbonate for a number of animals from tiny sea snails to Alaska King crabs to construct and maintain their shells at certain times of the year,” said Jeremy Mathis, an oceanographer at NOAA’s Pacific Marine Environmental Laboratory and lead author. “This change due to ocean acidification would not only affect shell-building animals but could ripple through the marine ecosystem.”

A team of scientists led by Mathis and Jessica Cross from the University of Alaska Fairbanks collected observations on water temperature, salinity and dissolved carbon during two month-long expeditions to the Bering, Chukchi and Beaufort Seas onboard United States Coast Guard cutter Healy in 2011 and 2012.

These data were used to validate a predictive model for the region that calculates the change over time in the amount of calcium and carbonate ions dissolved in seawater, an important indicator of ocean acidification. The model suggests these levels will drop below the current range in 2025 for the Beaufort Sea, 2027 for the Chukchi Sea and 2044 for the Bering Sea. “A key advance of this study was combining the power of field observations with numerical models to better predict the future,” said Scott Doney, a coauthor of the study and a senior scientist at the Woods Hole Oceanographic Institution.

A form of calcium carbonate in the ocean, called aragonite, is used by animals to construct and maintain shells.  When calcium and carbonate ion concentrations slip below tolerable levels, aragonite shells can begin to dissolve, particularly at early life stages.  As the water chemistry slips below the present-day range, which varies by season, shell-building organisms and the fish that depend on these species for food can be affected.

This region is home to some of our nation’s most valuable commercial and subsistence fisheries. NOAA’s latest Fisheries of the United States report estimates that nearly 60 percent of U.S. commercial fisheries landings by weight are harvested in Alaska. These 5.8 billion pounds brought in $1.9 billion in wholesale values or one third of all landings by value in the U.S. in 2013.

The continental shelves of the Bering, Chukchi and Beaufort Seas are especially vulnerable to the effects of ocean acidification because the absorption of human-caused carbon dioxide emissions is not the only process contributing to acidity.  Melting glaciers, upwelling of carbon-dioxide rich deep waters, freshwater input from rivers and the fact that cold water absorbs more carbon dioxide than warmer waters exacerbates ocean acidification in this region.

“The Pacific-Arctic region, because of its vulnerability to ocean acidification, gives us an early glimpse of how the global ocean will respond to increased human-caused carbon dioxide emissions, which are being absorbed by our ocean,” said Mathis. “Increasing our observations in this area will help us develop the environmental information needed by policy makers and industry to address the growing challenges of ocean acidification.”

From the paper’s conclusion: “While it is still unclear what ultimate biological impacts will result from
these biogeochemical changes, it is probably safe to assume that they will have detrimental effects on ecosystems that are already under pressure from rising temperatures and other climate-driven stressors”

Yep, this is what it has become.
By the way, although it isn’t quoted in the above, the word ‘corrosive’ appears twice on page 5. I actually work with ‘corrosive’ chemicals. They really are corrosive, in that they will “damage and destroy”. Some water that has become less alkaline, well, that would be in my lunchtime drink.

I reverse-osmosis filter my drinking water before I drink it. The system has a re-mineralisation filter on it which turns the water slightly alkaline prior to the tap. Bad gut PH can inhibit beneficial gut bacteria, as can pesticide residues in gmo crops, or even non-gmo crops sprayed with “pre-harvest” glyphosate treatments (like the ‘healthy oat breakfast/snack’ which is soaked in the “probable carginogen” glyphosate (WHO)).

Kitefreak, the stomach provides a pH of around 2.0 which is necessary to digest the food that you eat. I doubt that making your water slightly alkaline has much influence on the pH of that water when it is absorbed after entering the stomach.
The pH of the water that you drink isn’t likely to influence the pH within the intestine since the duodenum neutralizes the very acidic material leaving the stomach. That material is much more acidic than your drinking water could ever be.
So far, all I have seen is baseless speculation that glyphosate is a “probable carginogen [sic].” Glyphosate is expensive. Why would a farmer “soak” his crop in Glyphosate? One of the advantages of glyphosate is that it takes only an extremely small amount to kill most sensitive plants.
Add “corrosive” to the list of scary words such as “acidification, that are being redefined in an attempt to mislead and frighten the public.

More fear mongering via bad models. During the Cretaceous when atmospheric CO2 is estimated to have approached 4000, and palm trees grew in Antarctic, calcium carbonate deposits were at a peak, suggesting calcium carbonate shell formers were also at their peak. The Cretaceous period is in fact named for their massive chalk deposits. As atmospheric levels fell towards modern levels during the Cenozoic and the earth cooled, calcium carbonate shell producers diminished as witnessed by shrinking chalk (calcium carbonate) deposits.
It is safe to assume these guys are pulling their future projections about ocean acidification from unsavory parts of their anatomy.

First, it is unlikely that CO2 dissolving in the oceans will be able to detectably affect the complex buffer known as seawater.
Second, as CO2 has been 4 to 10 times higher than now during most of the last 600 million years, it is likely that these species will have no problem handling the relatively tiny increase the war mists are panicking over right now. Marine life is much more resilient than they want us to think and survived a much wider range of conditions than we are experiencing today..
Also, maintaining shells in cold water is inherently a dissolution problem as calcium carbonate is more soluble in cold water than warm water. Higher CO2 actually means increased carbonate in the oceans as the long equilibrium from carbonic acid to bicarbonate to carbonate is pushed toward more carbonate by having more CO2. And the protons given off by carbonic acid and bicarbonate cannot affect their own equilibrium. Only an outside source of protons would alter the equilibrium.

Far more than ten timed higher prior to the Permian. The highest RCO2 estimated by Geocarb III is a little above 25 slightly more than 500 MYA. The max during the Mesozoic was about 10, and corals and molluscs flourished. The maximum during the early Cenozoic looks to have been about 4 (ca. 1,600 ppm). The trend since then, including the minor uptick at present, is downward. The obvious conclusion is that without either a reduced green plant mass or and increase in the release of carbon into the atmosphere, a second Permian event is very possible – due to low atmospheric carbon.

considering the the ocean is currently caustic (ph > 7) and most creatures rely on a layer of mucus for protection, you would think they would look forward to a corrosive (ph < 7) environment.
most fresh water on the other hand is corrosive, with ph < 7, yet we don't think twice about drinking it.

Caustic and Corrosive and not very clear terms. They are both relate to damage due to a chemical reaction. These terms also have other figurative meanings. It is true that Acids are referred to as Corrosive and Alkalines are referred to as Caustic. Hence, forgive me as I will use the terms Acid and Alkaline in my reply; if you wish you can replace these terms with the equivalent Caustic/Corrosive terms.
Acids contain H+ ions accepting electrons and most metals have week bonds with electrons; this leads metals to give them up easily; this process is known as rusting. Alkalines has OH- ions and freely donate electrons; not a problem for metals.
The shells of shellfish are composed of Calcium Carbonate. These organisms use a Calcium Carbonate crystal, known as Aragonite, present in water to grow their shells. Aragonite is reactive with acids so an acidic environment reduces Aragonite levels. A reduction of Aragonite in seawater affects the ability of these organisms to form.
Plankton rely highly on Aragonite and lay at the bottom of the food-chain so a reduction in plankton affects higher organisms.
A bit of chemistry on the reaction of Calcium Carbonate (CaCO3). For a monoprotic acid (HA), the reaction is:
HA + CaCO3 –> H2CO3 + CaA2 (CaA2 is the salt byproduct where A is dependent on the type of acid salt)
H2CO3 (Carbonic acid) quickly decomposes in water:
H2CO3 –> H2O + CO2
Hence, the complete, balanced, reaction is:
2 HA + CaCO3 –> H2O + CO2 + CaA2

It appears that climate science again has the chemistry backwards. CO2 is necessary to create shells:
Calcium Carbonate Minerals in Water
Calcium carbonate chemistry is more complicated when it comes to understanding which polymorph will crystallize out of solution. This process is common in nature, because neither mineral is highly soluble, and the presence of dissolved carbon dioxide (CO2) in water pushes them toward precipitating.

however, when you add acid to a buffered base, you are not acidifying the solution, you are neutralizing the solution.

Change in “the amount of” calcium (contributing pOH) vs carbonate (contributing pH) indicates either “alkalinization” or “acidification” for increase or decrease respectively. When we quibble over their use of the more familiar term (for decrease in pH, which they are descrying) we are providing them a straw man holding a red herring wrapped in a distraction.
They don’t need our help for that. Shouldn’t we stick to the science, which they find so slippery?

NOAA agree with you, the term ‘ocean acidification’ is pure alarmism.
pH values above 7 are commonly referred to as “basic” (or “alkaline”).
These common terms engender confusion, because a pH value does not directly reflect a quantitative measure of the concentration of bases in the solution, nor do high pH values constitute a measure of alkalinity. What is expressed by pH values >7 is still the acidity of a solution, it’s just that the acidity (H+ concentration) is very, very low (less than 10-7 (or 0.0000001) moles per liter, to be specific). To determine the alkalinity of a solution (which is related to the concentration of bases), a separate, detailed laboratory analysis must be run on the solution, so it is incorrect to characterize the change in hydrogen ion concentration as a decrease in alkalinity.
Calling this phenomenon “ocean acidification” when surface seawater will remain “basic” under future emissions scenarios is alarmist

Your reading comprehension is poor or you are trying to be cute. A PH of 7 is neutral, period. Going towards that value is neutralization, period. I took College chemistry. When we took a PH that was different than 7 and made it go to 7 it was ALWAYS called neutralization. Now NOAA is trying to redefine PH to fit their alarmist purposes. PH of 7 is not an arbitrary point on the PH scale as is a zero reading on the Fahrenheit or Celsius scales. Absolutely pure water has a PH of 7 and NOAA is trying to say it is acidic so they can make the alarmist emotive claim that the oceans are acidifying. Yes the oceans are acidifying if absolutely pure water is acidic!

Mr Courtney,
Eh? When it includes, “This change due to ocean acidification…” it means that you can dismiss it – because they suggest less alkaline is acidification. If you have a glass of water saturated with salt (sea water, if you like) and you add a [really] tiny amount of sugar, you haven’t ‘sweetened’ it. The term ‘acidification’ rules out taking anything else in it seriously.

Big Jim:
Acidification is defined as decrease in pH (equivalent to increase in pOH). It does not depend on whether the concentrations becoming more equal or less equal (pH + pOH == 7.0)*. Less alkaline IS more acidic, no matter how unfortunate is the public response to the terms they propagate to their … ahem … base. (We could also say more corrosive is less caustic, and perhaps we should.)
Likewise, adding sugar to a salty solution DOES sweeten it, although that example is not to my taste. A day which goes from above to below freezing HAS cooled. Refusing to take technical terms seriously and surrendering the battlefield is a tactical error.
*Water in equilibrium has 10 to the power of –14 concentration of “hydrogen” (hydronium or H3O+) ions multiplied by concentration of hydroxyl (OH-) ions.

Listen. I know that the sea is alkaline. It’s still alkaline in reality. “Acidification” is use of a politicised language. But that language got them published so it was expedient. It has no impact on the real meaning. It’s still alkaline. But they are using publishable language to get a paper published.
The paper may still have some truth in it.
Jim from Maine makes a good point. It took a long time to get this published.

BillK, speaking as a chemist, I’d never say that having reduced pH from 8.1 to 7.8 is “acidification.” If anything, I’d describe the process as having made the solution slightly less alkaline.
“Acidification” is technically correct but a chemical misconstruction, is never used by laboratory professionals to describe the circumstance of having slightly lowered an alkaline pH, and is dishonestly employed in consensus climatology as a scare term.

I have enough problems with the word ‘pause’, and I have made efforts to get people to stop using the term (as it specifically implies that you know future events). The term ‘acidification’ is used wrongly over and over again, on both sides of the climate debate now. IT IS TO MAKE SOMETHING AN ACID. It is NOT to make something less alkaline.

All very well MC but they comment on the lowering of the ocean’s calcium carbonate content as a problem for moluscs. Firstly calcium carbonate does not exist in solution but as individual ions. The more CO2 dissolved then the carbonate ions increase. The pH remains alkaline because of the bicarbonate/carbonate feedback process keeps it high. To argue that increased CO2 will reduce pH and reduce aragonite production, thus reducing the molusc building blocks is contrary to reality.

From the report: “Melting glaciers, upwelling of carbon-dioxide rich deep waters, freshwater input from rivers and the fact that cold water absorbs more carbon dioxide than warmer waters exacerbates ocean acidification in this region.”
Since I don’t know (does anyone else?), how do/does:
a) “melting glaciers” exacerbate ocean acidification?
b) “upwelling of carbon-dioxide rich deep waters” exacerbate ocean acidification? And what the heck IS “carbon-dioxide rich water” anyway? Can someone explain? Is ALL “deep water” CO2-rich?
c) “freshwater input from rivers” exacerbate ocean acidification?
d) “the fact that cold water absorbs more carbon dioxide than warmer waters” EXACERBATE ocean acidification? So what do they want?? Ice or Warm water in the Arctic?

Obviously Glaciers have absorbed all that acid rain, and if cold enough, all that acid snow. So when in 5000 years or so, this particular bit of glacier hits the ocean, the oceans will become more acid.
“Carbon dioxide rich water” is created when outgassing undersea volcanoes add CO2 which becomes dissolved in deep ocean waters. Eventually along certain coasts this cold water upwells, west coast of Africa, South America and of course, Antarctica, are some of them, thus making water more acid. A human related addition is from CO2 sequestration, when CO2 is pumped down into the deep ocean to a level where it is liquefied under pressure and dissolves, thus making matters worse.
“Freshwater input from rivers” contains massive amounts of dissolved CO2 from the atmosphere, and plenty of sulphur dioxide and nitrogen oxides from human industrial processes. All very acid!
Cold water absorbs CO2 better than warm or hot water, so as the North Atlantic Drift gets further and further north, and as it gets colder, it absorbs more CO2 and gets more strongly acid.
But as the Oceans are very basic to start with (not “Alkaline”) the absorption of CO2 would barely make a noticeable tad of difference.
Very had indeed to keep up with this!

.glaciers bring more calcium bicarbonate from soil that would overrun the slight acidic ph of melt.
.CO2 rich bottom waters are primarily due to benthic microbial respiration.
.riverine waters are rich in bicarbonate and dissolved CO2 is insignificant part of DIC
.cooling of seawater adds negligible decrease in ph. average oceanic ph = 8.1 bringing massive CO2 into solution would raise it by 0.1 due to temperature.
.basic and alkaline are the same thing.

Depending on source, almost all freshwater has a lower pH than seawater. Been going on in the Arctic for a long time. Upwelling water from below photic zone has naturally lower pH and elevated CO2 –and all other phytoplankton nutrients–from decomposition of photic zone detritus. Those upwellings are what cause thrivong coastal fisheries. More photosynthesized bottom of the food chain food, more food all the way up the chain. Cold water thing is just Le Chatellier’s principle at work.
But the truth of all those things does not make this a good paper. It is obviously biased, wrong on some counts, and incomplete on others. And, the sampling work,does not provide the annual pH and aragonite pattern to say anything meaningful biologically. See my long comment below.

Pago Pago harbor is one of the most polluted places you could hope to find. Yet shell grows on boats at a rate I’ve never seen anywhere else in the world. In only a matter of days we had about 1 inch of white shell covering the hull, propeller, everywhere. Not barnacles, more like very fine tube worms.
We could barely get out of harbor spewing black diesel fumes from a badly overloaded engine, before the water was clear enough that I dared go over the side and scrape the hull and clear the thru hulls.

June 17, 2015 12:31 pm

From the abstract there is this: “some of the largest commercial and subsistence fisheries in the world may be under tremendous pressure.”
In the past if there were any detrimental changes to a fishing industry it was usually as a consequence of the pressure that industry was applying to a given fish stock; e.g. The Grand Banks, North Sea Herring, among others, where fish stocks were exhausted.
The attention given towards a supposed ocean tendency towards a neutral pH can take attention away from good husbandry which in itself is already in conflict with financial pressures. However, I understand there are strict fishing quotas around the area in this topic designed to preserve stocks.
This might seem off topic but I will make a loose connection between the abstract statement above and this from an Afghan bird hunter (http://www.bbc.co.uk/news/world-asia-23486991):
“Thirty years ago, I used to shoot 500-700 sparrows a day with my sling shot,” says Haji Shakoor, 57, from Salang valley. “The sky used to be full of birds. But now it seems so empty.”
Indeed Mr Shakoor.

Maybe, but the point is Mr Shakour is surprised that there are less birds around even though he was doing his damnedest to remove them.

Went and read the paper. You know where it is going when in the intro they declare the ocean is already 30% more acidic. Well, pH is a log scale. They mean the decline from guesstimated 8.2 to measured 8.11 at station Aloha in the barren Pacific north of Hawaii. The Artic ocean is anything but barren. Deadliest Catch is pretty good evidence. Finally, they point to commercial disruption of Alaskan fisheries. But pelagic fishes, and crabs, don’t rely on calcification either directly or via their food sources. Calcification is about shellfish and corals and coccolythophorids. Arctic Shellfish (clams) are important food for walrus. Otherwise there is no big biological concern. Its a crab/fish/seal/polar bear Arctic biosphere.
The paper makes a major mistake in the tradition of AR4’s goof. The pH and aragonite saturation calculations omit the enormous buffering capacity of seawater, which for any pCO2 roughly halves the pH and carbonate saturation impact. The calculations are chemically incomplete, so wrong.
The coupled model saturation outputs for the present based on RCP 8.5 did NOT well match the water samples. See table one, and the oddles of text armwaving this little detail away. One valid reason is ‘acidic’ freshwater river inflow. Those inflows also bring additional dissolved (and undissolved) carbonate from sediment. That input detail, however, was not included.
Part of the modelled effect was less summer ice cover so more CO2 absorption so more ‘acidification’. This ignores the accompanying summer increased biological activity that would raise pH by increasing photosynthetic comsumption of pCO2. The very same logic flaw that PMEL made in drawing its scary but false conclusions about the Netarts Bay oyster hatchery. See essay Shell Games in Blowing Smoke.
About the only good thing is that we now have an October salinity, pH, and aragonite concentration baseline for these three Arctic seas. What we still do not have is the annual biologically driven pH cycle that would indicate whether shellfish spawn (a summer event when planctonic food is at the maximum) might be affected in the future. The PMEL ‘goof’ remains unadressed for the Arctic.

Excellent post ristvan. Also missing is the fact of numerous observations of improvement in calcification of disparate marine life in realistic rates of PH change due to increased CO2.
http://www.co2science.org/data/acidification/acidification.php
“In the final graphical representations of the information contained in our Ocean Acidification Database, we have plotted the averages of all responses to seawater acidification (produced by additions of both HCl and CO2) for all five of the life characteristics of the various marine organisms that we have analyzed over the five pH reduction ranges that we discuss in our Description of the Ocean Acidification Database Tables, which pH ranges we illustrate in the figure below.”
“The most striking feature of Figure 11 is the great preponderance of data located in positive territory, which suggests that, on the whole, marine organisms likely will not be harmed to any significant degree by the expected decline in oceanic pH. If anything, in fact, the results suggest that the world’s marine life may actually slightly benefit from the pH decline, which latter possibility is further borne out by the scatter plot of all the experimental data pertaining to all life characteristic categories over the same pH decline range, as shown below in Figure 12.”
At PH decline from control of .125 calcification, metabolism, fertility, growth and survival all moved into positive territory.

Donb
June 17, 2015 12:51 pm

Their abstract does not give pH. Today’s ocean pH ranges over 7.5 to 8.4, average ~8.1. Over the period of 100 to 200 million years ago, when marine life with carbonate shells flourished and atmospheric CO2 was higher (see comments above), the average ocean pH was ~7.6.
Obviously lots of uncertainty in future extrapolations.

Also, should note, when the atmosphere was 6000ppm the oceans were not acidic, so no way they will become acidic at a mere 400ppm. This is because the ocean is a buffered system, with an enormous amount of limestone (CaCO3) deposits, which maintains the pH of the ocean at ~8.0 at equilibrium, regardless of CO2 level. Also, at constant pH, HCO3- and CO3– both increase as more CO2 is dissolved into the water.

This one has been sitting on the pile for a while but they needed to push the message about Arctic fisheries being threatened so it was given a starting position on the grid. It seems to me “it is possible” that there is a coordinated effort to manipulate public and political opinion prior to forcing through damaging agreements in Paris. If they cannot get something in Paris the game is up and the whole house of cards will come falling down.

What I laughed at was the vast amount of data that backs up their model: Two month-long trips.
Considering the great shifts the arctic goes through, year to year (not to mention MWP to LIA), a couple of summer trips is too little data to determine much of anything.
However they set out looking for specific data, to “validate” their models.

It appears that climate science again has the chemistry backwards. CO2 is necessary to create shells:
Calcium Carbonate Minerals in Water
Calcium carbonate chemistry is more complicated when it comes to understanding which polymorph will crystallize out of solution. This process is common in nature, because neither mineral is highly soluble, and the presence of dissolved carbon dioxide (CO2) in water pushes them toward precipitating.

But, wait a minute, the reef isn’t metal, or anything remotely like it, it’s made of calcium carbonate, which is a salt of carbonic acid.
A different and stronger acid would be able to rob the calcium from out of the salt, leaving the carbonic acid on its own (and usually to dissociate into CO2 ‘fizz’ and water since it has only limited solubility) but the same acid that formed the salt cannot do that. At least, I’m reasonably sure it can’t. Perhaps some of the chemists in here would like to confirm or refute that point as chemistry isn’t my main subject.
If so, just shows how they dream these things up which sound plausible until you look at what they are saying more closely. You then realise it is junk science.

=============
you are correct. adding CO2 will precipitate more CaCO3. CO2 cannot dissolve CaCO3 in seawater, because that would produce even more CO2, which would dissolve more CaCO3, which would produce more CO2.
If things worked the way climate science suggests, there would be no CaCO3 in the oceans as the smallest amount of CO2 would lead to a runaway reaction.

This is incorrect, addition of CO2 to seawater causes a reduction in pH and a reduction in [CO3–]. The solubility of CaCO3 is governed by its solubility product: Ksp=[Ca++]*[CO3–]
In seawater [Ca++] is constant so CaCO3 solubility decreases as [CO3–] decreases. Because the solubility of CaCO3 increases as temperature decreases and as pressure increases, below a certain depth CaCO3 dissolves, this depth is shallower for aragonite (the form mostly used in shellfish) than for calcite. Due to the lower temperature in the arctic you’d expect this to occur nearer the surface.

Bjerrum plot showing the relative proportions of [HCO3-], [CO32-] and [CO2] to DIC in seawater with different temperature, salinity and pressure (heavy curves are for S=35‰, T=25ºC, P=0bar, narrow curves are S=35, T=0ºC, P=0bar, dashed curves are S=35, T=0ºC, P=300bar). The shaded region reflecting the range of modern (annual average) ocean surface, with the hashed region reflecting the corresponding projected year 2010 range: taken from the global ocean geochemistry model projections of Turley et al. (2010). To put ocean chemistry into some perspective, some common substances and their respective pH are shown at the bottom (scale is same as upper panel). pH values for foodstuffs are from Bridges & Mattice (1939), and for household products from (Hoffman et al. (1989). Note that different brands and preparations can give different pH values (up to ±0.5 pH units) — typical measured values are shown.

Don’t the carbonate and H promptly get together, forming bicarbonate and thus buffering pH change?

Since the seas are alkaline, they are already somewhat corrosive. Any so called acidification will simply move them towards neutrality, making them less corrosive.

More corrosion, then why according to the BBC and this is a direct quote” the great barrier reef has been spared and is not on the endangered environment list” BBC speak for no problems with acidity in the oceans

The short of it is this.
They have no science or measurements showing it is happening and haven’t detected any impacts from anything remotely corrosive, but their programmed models show it could happen.
And as usual they push out the time when we will be able to detect this corrosion to years beyond their careers and out of reach of any consequences or accountability.
Marvelous.

Proving the theoretically possible is easy. Proving what is just most likely using assumptions is impossible. They left out most other theoretical physical possibilities while also ignoring adaptation – a proven aspect of all life. Other than that, conjectural quasi-science at a third grade level.

Meanwhile back in the actual Arctic…
Ice conditions have been unusually severe along the west coast of Greenland, affecting fishing in that area:
http://www.undercurrentnews.com/2015/06/09/high-coldwater-shrimp-prices-help-royal-greenland-overcome-harsh-winter/
Royal Greenland expects profits for the year on a slightly higher level than in 2013/2014, despite the fact that the results for April and May were “very adversely affected by the ice situation along the west coast of Greenland”. The company expects to be able to compensate for the lost income when the ice is gone, it said.

This could be a further indication of strengthening Arctic ice and a possible robust minimum this year.
Ort maybe those Greenland shrimp dislike swimming around in acid – I know I would.

Precisely! This is exactly why there are no gastropods or bivalves in fresh water (which has a much lower pH than seawater). This is also the reason why CaCO3 shell building organisms didn’t evolve until the Miocene when atmospheric CO2 levels decreased. /sarc

Not true. There are plenty of fresh water clams and mussels.

Which claim is correct, “the heat is hiding in the oceans” or ” the oceans are becoming more acidic” . They both can’t be true at the same time. If the oceans are getting warmer then they are less able to hold co2 and as a result release more co2. And if they are becoming more acidic, then the oceans are getting cooler. So what’s causing the reefs to die? Warmer water as reported in some journals or more acidic ocean water? Does CAGW know when they publish contradictory claims? Or claims that don’t square with observations, predictions, or relevant data ? I think they will just ignore this slight inconvenient argument (as many others) and slog ahead or answer with some totally ridicules new claim…. like warmer weather causes more snow.. no mention of where or how it’s cold enough to snow in the first place. (which invalidates the claim that “when water vapor releases latent heat the heat is retained, because it is a feedback system which causes it to get warmer still “) .

If the oceans are warming at too low a rate to keep up with the increase of CO2 in the atmosphere (which is the case at present) then the flux of CO2 is into the ocean and as a consequence the oceans are warming and pH is reducing at the same time.

The problem is, as been shown by the IPCC, is that a little bit of heat makes a big difference. The amount of heat per them overwhelms any amount of co2 presently in the atmosphere. Which is in their view also responsible for sea level rise. Do the math, the statements can’t be both true at the same time. Doing the math, if the ocean has warmed as much as claimed, the level of rise should be dramatic not in millimeters per decades. In the year 2002, the alarm was exactly correct for CAGW. Canal St in NYC should be underwater, not 15 years from 2015.. NOW. What happened? What is perplexing is that at least half or more of the co2 currently being produced is disappearing somewhere, which is in comparison overwhelming when compared to the amount of co2 produced 50 years ago. Additionally, the amount of sink have decreased. You have a warmer more acidic ocean, tropical rainforest have diminished greatly. Which also brings me to another topic, the amount of time co2 remains in the atmosphere. If, well not if, it is that half of the co2 in the last 10 years has disappeared, man made co2 that is, so if so much co2 is being eliminated somewhere, how was co2 not completely gone form the atmosphere before man made co2? How do we know half of the co2 in the last 10 years has disappeared? It would have showed up in the ppm. In fact I have the rate of co2 going somewhere much higher that 50 %. The sink looks like it is accelerating

I thought corrosive means something that corrodes. If Aragonite is already corroding in seawater now the term should apply? What am I missing?

Aragonite dissolves in seawater when its solubility product (Ksp) falls below 6X10^-9 (at 25ºC), in the current ocean this occurs typically below a certain depth where pressure and temperature result in a higher Ksp, CaCO3 increases solubility at lower temperature and higher pressure.
The Ca++ concentration of 0.01mol/L is constant in the ocean and any reduction of pH leads to a lower concentration of CO3– therefore a pH of 7 is more corrosive than the present composition of seawater.
In fact in the N Pacific at present the pH at 500m depth is about 7.2 by which point aragonite has dissolved.

With the ocean at ~8.1 pH adding more CO2 will make the ocean less corrosive. Seriously, these reporters should talk to somebody with some science background before they publish their stories.

Words do mean things…but not always the same thing in a different context.
A “caustic comment” may come from an “acid tongue”. Both result in damage and so mean basically (8-)) the same thing in that sentence.
But if the context is chemistry, then “caustic” and “acidic” are opposites in terms of pH.
“Corrosive” as in “oxidized”? Is that with or without Oxygen?

Wait a minute, the shells of King Crabs are made out of chitin, a polysaccharide, not calcium carbonate. Not only that but both acidic and alkaline solutions are corrosive. With the ocean at ~8.1 pH adding more CO2 will make the ocean less corrosive. Seriously, these reporters should talk to somebody with some science background before they publish their stories.
