only 350 kilometers from the North Pole, maybe 50% of the sea is covered with ice, however, says that there is no data on the ice at this latitude

Where is the ice? We are now on 83.20N which is very close to the North Pole and still no permafrost (head here to learn more about my trip to the Arctic). We especially among small icebergs, thin one and two years, with very few of the largest, most difficult and ice "several years", or permanently greater than can be expected in these latitudes.

Our pilot ice, Arne Sorensen took the helicopter, but little change, even as far north as 83.50 - only 350 miles from the pole. Just find a mirror large enough to allow the mooring of 50 meters long Arctic Sunrise scientists on board to carry out their experiments showed harder than expected iceberg - something that many think it is almost unknown in this latitude

The obvious conclusion is that the ice has declined much more than last year and will verify the data from previous years to confirm this satellite. But it can actually be much less ice in the Arctic figures suggest satellite.

In winter, when the sea surface is frozen here, scientists can be sure that the amount of ice there. But in the summer months when the ice melts and there is much more water around, the satellite can become confused.

You might think that the melt water sitting on the ice-free water, it may not be able to tell the size of the ice or the distance between them, but may have problems to "see" the ice due to clouds and fog.

In summary, the effect of the merger, it is much more difficult to quantify the amount of ice there and the satellite tends to see more ice than it actually is. This is why monitoring groups, as NSIDC University of Bremen or try to compensate with the filters of time or calculating ice extent for several days and not the individual.

Julienne Stroeve, NSIDC expert ice people expected to attend the recording disk low ice extent rather than a few days -. He photographed the ice conditions a few hours

When she returns, she hopes to match their real-time observations of ice conditions with satellite data. It is speculated that low fog conditions we experienced might suggest that there is more ice than it actually is.

In all cases, the situation is very serious. Two satellites and human observation suggests that the ice is so thin in much of the Arctic that no matter how hard freezes in the winter because it melts in summer. That means no summer ice in the Arctic is much earlier than the models predicted.

Curiously, we begin to see that the Arctic explorers and visionaries like old Elisha Kane, Isaac Hayes, Captain WE Parry and Sir John Barrow expected to find. Widely accepted since the 16th century there was a hot lake at the north pole, and was another continent beyond the ice. The problem encountered by explorers then to go beyond the bag of ice that blocked his path. It is this perspective that led Arcadia land adventurers.
Today, the possibility of free and easy access Arctic ice across the world has become the dream of oil companies, mining and transport. The benefits that are placed on the open sea ice are similar to those seen by the British as a free passage over the world to China and east.
