From the “pictures actually do matter” department…NSIDC’s Mark Serreze is thrilled to get them
from Science News
Hundreds of high-resolution satellite photos of the Arctic sea ice taken during the past 10 years should be immediately declassified and released to the scientific research community, the National Research Council reported on July 15. Shortly after, the United States Geological Survey made about a thousand of the images available to the public through the Global Fiducials Library.
“Most people from the scientific community are not aware that these images have been collected,” says Stephanie Pfirman, chair of the NRC committee that wrote the report. “They’ll be very excited to see these results.”
The photos could help scientists study the rapid changes taking place in the Arctic, the committee members say. Current research efforts that might benefit include studies of polar bear habitats, of the movement of ice floes and of the formation and evolution of melt ponds — bodies of water that form on ice sheets and accelerate their melting.
“There are a lot of processes that we still don’t have a good handle on,” such as why Arctic ice is melting faster than models predict it should, says geographer Mark Serreze of the University of Colorado at Boulder. High-resolution satellite imagery is “just the sort of thing we need” to answer these questions, he says.
The satellite project began in the mid-1990s when environmental scientists teamed up with members of the intelligence community to create a program that would see whether “classified assets”, which might include aircraft or satellites, could collect data useful for scientific purposes. Called Medea, the program approved the use of pre-existing satellites to take pictures beginning in 1999 at one-meter resolution of four Arctic sites. Two additional locations were added in 2005. The only catch was that the photographs could not be released until a committee had determined that they were scientifically useful.

Just a thought about potential applications to polar bear studies. This might be just me showing my ignorance, but at 1 meter resolution wouldn’t you do %&$@ing well to spot a white bear in the snow?
to AlexB… “include studies of polar bear habitats”. Habitats, not habits. 🙂
Damn, the US Army has discovered where we, Canadian, have hidden our Canadian bacon and maple sirup. We will have to move our stocks again.

At 1 meter resolution you might see more details of those habits than you wanted to.
One can only hope that NSIDC will use this treasure trove to increase their understanding of what’s happening to the Arctic ice, rather than sift through the images to find confirmation in support of a belief they may already hold.

That was my first thought too. Maybe they are looking for the drowning ones…
Photos over 10 years hardly establish a climate trend.
You get regions that experience very warm anomalies for a few years, and then get real cold again. One has to look at the entire arctic and Antarctic as a whole.
This is fantastic news. Now if we can get the subs to release temperature data, folks could start fitting together pieces of a very complex puzzle.

1 metre resolution will be sufficent to count Polar Bears!
One would assume that there are images of polar regions taken by military satellites dating back to the 1960s. The earlier ones won’t be such high resolution, but they should be sufficient to show changes in ice extent.

Strange language reveals a strange mindset.
I would be saying something like “improve our models” or “build some decent models” or “improve our understanding – which could lead to building some decent models”
I’m wary of the word “model” now. If we say that water will boil at 100 degrees C – is this a model ? Or in my own field of civil engineering if we say a beam will deflect by 3mm under a certain load – is this a model ? We used to call them calculations.
Sat images provide a wealth of information and a lot of opportunity for scientific research. But also for spin and manipulation, as any picture nowadays.
A lot is solved if every sat image used in publications, carries the resolution, the date and the geographic position to it.
Otherwise we could be flushed with horror stories of the arctic in mid winter documented with images from the summer melt.
In the mean time, the general public has become indifferent for alarmism.
AGW and Climate Change score the lowest ratings in the poles and the numbers are sinking fast, not onlu in the USA, but also in Canada, Australia and in Europe.
People have lost trust in Government and know when they are conned.
Opinion today is highly influenced by the internet with blogs like this and mother nature demonstrating the opposite of what the warmists claim.
If the US Senate makes the right decision, Copenhagen will fail and the doctrine will collapse.
I’d like to see the cloud cover over the area of the 1999 Gakkel Ridge volcano to see if it represents the vapor cloud over open water or warmed ice or whether it is ordinary clouds. Those images may be in this bunch of photos. Pictures of it do exist, that’s why I know the area was obscured by clouds. A researcher with access to the photos said so last year, but was not curious enough to analyze the clouds themselves. It was someone who wanted to pooh-pooh the suggestion that the volcano contributed to ice melting.
The reconstruction of 30 years of ice flow in the Arctic at DotEarth shows an area of open ice appearing over the area of the volcano.

Looking at SST anomalies, there is a concentric pool of warmth southeast of Wrangel Island in the Chukchi Sea. Given the fact that we know that more than one volcano in the Aleutians and on the Russian side of the far northern Pacific are quite active at present, it is at least tempting to investigate underwater vulcanism near the warm bull’s-eye.
Glancing at the anomaly map again, another spot where such activity seems possible is between Iceland and Greenland.
Can underwater vulcanism generate sufficient heat to assist in the annual melting of sea ice? We don’t know.
One more reason that the science is not in, although some scientists have explored the possible connection.

Hey you can watch your TV, Discovery Channel “Most Dangerous Catch” and see how fast the ice is spreading south.
Watch ‘Ice Road Truckers’ to see how ‘bad cold’ it’s getting in the Arctic areas of planet earth.
Getting cold fast … The daily trends tell the climate, right? Or did I miss something in math about the earth being 4.5 billion years old — Wonder what that works out to be in days?
Do we have any sat photos of the PETM era?
I wonder why they call it tundra? And not just peat bogs like we do in Florida? And where did the peat come from that far north — Lots of questions few real answers.
Most scientists would say — In the case of AGW, the GCMs and their theory predicts that there should be a measurable hotspot in the upper troposphere. Observations from satellites and weather balloons have been made, and no hotspot has been found. In a less politicized field, this would have been the end of it. Need new theory.
Mark Serreze seems excited by the prospect of putting his and others’ confirmation biases to work. Science with a mission isn’t science at all.
Here’s a prediction: as long as it looks like the studies will support the Global Warming/Climate Change now! agenda, this will be well funded and well publicized.
As soon as the results begin to contradict the “consensus”, however – watch for all the interest and all the funding to vanish overnight.
None of this is about science anymore.

With uber-climate-hysteric Serreze now promoted director of NSIDC (effective next august), don’t hope anymore.
From my experience with similar images, the issue will be coverage rather than resolution (which is likely re-sampled at lower resolution from the original).
1 meter resolution isn’t enough for polar bears. A stretched-out bear might be two pixels long and would have to be on a contrasting surface. You might see a white spot in the water, but you have to distinguish that from a small piece of ice. If polar bears swam in formation you might be able to spot that pattern. Individual bears in water or ice would be quite hard to identify.
With one exception: A bear next to a smooth area of ice with the sun on the other side low in the sky might cast a huge shadow. Because smooth surfaces and low sun are often present, that situation will happen more often than in other locations.
“Jack Hughes:
I’m wary of the word “model” now. If we say that water will boil at 100 degrees C – is this a model ?”
That is not a model, but the original definition of 100°C.
(It depends on air pressure, of course.)
Today 100°C is defined as 373.15K.
If you calculate the boiling point of water at altitude, then the calculation is based upon models (boiling point vs air pressure, air pressure vs altitude).
Melt ponds accelerate melting? I’d love to see the proof of that. Of course, no mention of melt ponds being counted as open water by the IR Boys.
This may have activated the law of unintended consequences-I’ll bet if this does not support the Fed Warmist position,-we will hear not a peep from this…
Here’s a new idea from NOAA… the Artic ice extend will shrink faster because the stronger winds will push the ice more and the ice will pack… reducing the area…

Is that a submarine pushing up through the ice in the photo? Must be a big one…
Death spiral caught on spy sat! YTDAW.
If the sats are so marvelous, why don’t the GW modelers trust sat temp data instead of tarmac-barbeque ground stations on steroids?
