This QOTW is from Pen Hadow, leader of the now farcical Catlin Arctic Ice Survey:
“It’s never wise to imagine that either man or technology has the upper hand in the natural world.”
That’s probably the only true statement published from the expedition.
BTW I was planning on using Steve Keohane’s art this time, but his “tinypic” links expired. Steve if you want to submit again (or if anyone wishes to) I’ll be happy to use the artwork submissions posted here.
Just to remind that Ohio submarine class (carrying two dozens of Polaris ICMB equal to 30xWWII explosive power) has long-term crew exposure limit 5000ppm of CO2, planned to be increased to 8000ppm.

also, today is the 42nd straight spotless day, tying the #8 longest spotless streak since 1849. tomorrow will tie the 7th longest streak, assuming no spots appear.

Except that most likely SIDC will reset the counter to zero for March 26 and perhaps even April 6., as noted and .

As mentioned elsewhere, the total count og 600+ days is the most interesting.
Sorry, the links didn’t work as intended

Yes, I’d like to see that picture, too. And its provenance.

Just updated:
Today was a landmark day for the team as they reached their 50th day on the Arctic Ocean. Any cause for celebration was naturally short-lived, however, since it looks as if the trend of open water may now become a regular feature of the team’s daily travel.
Today Ann, Martin and Pen encountered two such stretches of exposed ocean, the first being approximately 40 metres across and the second a slightly more manageable 10 metres across. Fortunately, both leads contained recently refrozen sections, allowing the team to cross to the next ice floe, albeit with a high degree of caution.
To make life even more interesting, the winds picked up towards the very end of the day and it started to snow quite heavily, reducing visibility to zero for the second time since the expedition began. Despite these adverse weather conditions and challenging terrain, navigation, physical fitness, teamwork and determination all paid off, resulting in the team conducting 10 kilometres worth of surveying today.
As well as the 7-9 hours worth of non-stop topographical observations being recorded each day (which include the height, consistency, size and frequency of pressure ridges, rubble fields, flat ice pans and open water), the team also conduct an additional 3-5 hours worth of measurements at static locations. These include measuring the thickness, density and temperature of the snow layer, and the thickness of the underlying ice, both above and below the waterline. The team currently take anything up to 76 such measurements each day.
As you say, the only truthful thing to come out of the expedition so far.
Anyone notice that the temperature has stayed constant at -25C for several days now on the blog (whether sunny, raining(?), or snowing as now). Another equipment failure?
Question: As the ice breaks up and if there are snowstorms how are they to be picked up?
Carsten:
I have also done some histogram & image processing analysis on the April 6
2009 spot :
http://www.robertb.darkhorizons.org/DeepSolarMin2.htm
see bottom of page.
It probably did not last long enough to pass SIDC muster, which is 30 minutes of visibility. The visibility at 1.07 contrast is the troubling part.
I have serious doubts that it was visible to the eye, showing itself only upon image processing.
Who takes the image, and how long to process it?
Are not sunspots supposed to be physically visibile, and not just CCD detectable?
Is this a case of the observer being unsure but CCD aided?
It would be fair for both parties to tell the story, what really happened, and go from there.

Indoor air quality includes
•temperature
•odor
•high or low levels of gases
Since CO2 is exhaled by people at predictable levels the content of Carbon Dioxide – CO2 – in air may be a significant indication of air quality.
A measure of CO2 indicates the amount of fresh air supply:
•15 cfm ventilation rate per occupant corresponds to 1000 ppm CO2
•20 cfm ventilation rate per occupant corresponds to 800 ppm CO2
Normal CO2 Levels
The effects of increased CO2 levels on adults at good health can be summarized:
• normal outdoor level: 350 – 450 ppm
•acceptable levels: < 600 ppm
•complaints of stiffness and odors: 600 – 1000 ppm
•ASHRAE and OSHA standards: 1000 ppm
•general drowsiness: 1000 – 2500 ppm
•adverse health effects expected: 2500 – 5000 ppm
•maximum allowed concentration within a 8 hour working period: 5000 ppm
The levels above are quite normal and maximum levels may occasionally happen from time to time.
Extreme and Dangerous CO2 Levels
•slightly intoxicating, breathing and pulse rate increase, nausea: 30,000 ppm
•above plus headaches and sight impairment: 50,000 ppm
•unconscious, further exposure death: 100.000 ppm
Carbon Dioxide Standard Levels
The recommendation in ASHRAE standard 62-1989 are
•classrooms and conference rooms 15 cfm per occupant
•office space and restaurants 20 cfm per occupant
•hospitals 25 cfm per occupant
or
Carbon Dioxide Level in PPM Resulting Conditions on Humans
300 (0.03% vol.) Nothing happens, normal concentration in air
3,000 – 5,000 Low concentrations cause increased respiration and headache
5000 (0.5% vol.) Lung ventilation increases by 5%. PEL
10,000 (1.0% vol.) Symptoms may begin to occur, such as feeling hot and clammy, lack of attention to detail, fatigue, anxiety, loss of energy, weakness in the knees commonly know as (jelly legs).
20,000 (2.0% vol.) Lung ventilation increases by 50%, headache after several hours of exposure
(5 to 10% vol.) Violent panting and fatigue to the point of exhaustion merely from respiration & severe headache. Prolonged exposure at 5% could result in irreversible health effects.
I am sooooo stupid.
When I was younger I actually thought that most people were interested in knowing as much about an issue as possible and researching what they didn’t know. How wrong I was. P.T. Barnum was right. Whether in entertainment, politics, (some might say the first two are the same), religion, education, or climatology – it is far more about what people WANT to believe than any dispassionate study of the information available.
It’s all a Three-Card Monte game.
Here’s another weird thing;
today their position is shown as 84°46’16.4″N, 127° 36’ 55” W. So they have 313.7 nautical miles to go to the North Pole (if they go in a straight line N; so the longitude doesn’t matter, just the lat). Which is nearly 581kms. And yet their “Estimated distance to North Pole” is shown as 548.93 km. What gives?
Reference CO2, what was the level when it was getting dangerous in the Apollo 13 capsule? Or was that a little bit of Hollywood? I seem to recall something in the region of 15%?
I see the Catlin crew mainly as victims of the overwhelming AGW madness which has been forced upon society.
I found this for US Navy:
1-24h – 40,000ppm
90 days – 5000ppm

Can someone enlighten me as to these wetsuits that they swim in when there’s no way round a lead? It all sounds very impractible.
I’m sure I read today that they had to swim but how? I’m finding that a tad implausible due to all that equipment and clothing at risk of getting wet?
Hmmm. I suppose they tow all this equipment in a raft? Does anyone else get the feeling that they are acting increasingly foolish. Wet suit or not, I don’t think it’s smart to jump in such a freezing ocean.
=====================================
How about an answer on where this high sun angle pic was discussed.
Aron (11:09:42)
“385ppm is a worldwide average.”
385 ppm is the CO2 concentration at an elevation of approximately 11,000 feet above the local sea level, when the wind is not blowing up the slope of Mauna Loa from the direction of the Kilauea CO2 emitter.
Only 77 ppm of the total 385 ppm is due to man-made CO2 emissions and only 0.4 ppm of the yearly increase of 2.18 ppm is due to man-made emissions.
Natural emissions of CO2 are not in balance with the natural CO2 sinks and never have been, with or without man-made CO2 emissions.
A wetsuit in that water sounds like an invitation to disaster. How’s about a dry suit? There is a big difference between a wet suit and a dry suit.
It’s here:

And the above is the WUWT article.
Judge for yourself.
That pic did NOT come from the Arctic in April.
High Alpine Lake in the USA or similar latitude in April, ok, but NOT in Arctic, not even on June 21st.
Reply: I keep posting this but it gets unnoticed. I am the one who found the video. The video was not posted for public consumption. I believe it was shot during training, probably in Resolute Bay, and this sequence WAS SHOT AT NIGHT under artificial illumination. Please limit conspiracy theories to known facts. ~ charles the moderator.
I’d be tempted to jump into a High Alpine lake under those conditions with a wet suit if I knew a warm fire was awaiting me in the Lodge a few minutes away. It takes nerve to do that much, because you know it’s going to be shockingly cold.
You are out of your mind to do that in the Arctic @ur momisugly 85 N with a wet suit.
Well, ok, if that is what they are doing, they are loony tunes.
