Arctic Danes

Jan Jorgensen reports on the specialised missions undertaken by the Royal Danish Air Force’s Eskadrille 721.

THE DEMANDING geography of Denmark, including Greenland and the Faroe Islands, presents the Royal Danish Air Force (RDAF) with a real challenge.

For over 65 years the primary role of Eskadrille 721 [Esk 721) at Valose Air Base outside Copenhagen has been to provide an airlift capability, while other missions involve it in sea-surveillance, ice-reconnaissance, search-and-rescue, and medical evacuations throughout the Arctic.

Over the years, these roles have been carried out by a variety of aircraft. However, three types have provided the backbone of

Underground boiler melt the Greenland ice

August 12, 2013. Climate scientists report that an unusually thin crust beneath the surface of Greenland partly explains the abnormally high rate of melting of its ice cap, as the hot magma mass beneath the surface act as one giant "kettle", reports the journal Nature Geoscience.

The temperature at the foot of the glacier, and, accordingly, their condition, at the same time depend on the flow of heat from the Earth's interior and temperature fluctuations on the surface. With this in Greenland there are areas where the foot of the glacier is melting, and which at the same time are

In the melting of the Arctic polar ice blame fires

In the melting of the Arctic polar ice blame fires Scientists prove

With the help of satellites, scientists have traced the movement of smoke and soot produced during the polar tundra fires in the northern hemisphere and have concluded that accumulated on the ice cover of the soot particles are greatly contributed to accelerated melting of the Greenland ice last summer.

Certainly, intervened to discuss events and clear weather over Greenland, and warm coastal ocean waters. But the appearance of soot factor also played a role. We all know how dark soot from dirty snow and ice are

The loss of sea ice in the Arctic were higher than expected

CryoSat-2 (the image of the European Space Agency).

August 13. The first satellite designed specifically to study the thickness of the polar ice caps of Earth, showed that sea ice in the Arctic disappearing faster than expected.

Preliminary results obtained with probe European CryoSat-2, said that last summer of the Arctic Ocean 900 km disappeared? ice. This is 50% higher than most forecasts. At this rate, in a few years, the Arctic will be completely ice-free in summer.

Tools other satellites already shown that the distribution area of summer ice in the Arctic from year to year

The tragedy of the Titanic could be repeated

A huge array of ice Ward Hunt, who for three thousand years, has joined the Canadian territory of Nunavut (Ellesmere Island) with Greenland has broken up into many pieces, which were to drift in the Beaufort Sea. These icebergs can be a danger to passing ships — the tragedy of «Tikanika» despite the remoteness, remember everything. Stretch of sea where drift ice blocks, navigable enough — there are major ports in Greenland. The original shelf area is 388 square meters. kilometers. Obviously, the glacier has broken up due to climate change.

The good news is that Greenland is melting, but slowly

The good news is that Greenland is melting, but slowly Scientists prove

Greenland ice melting is accelerating, and 2012 could be a record in terms of thawing ice cap on record. Since this process plays a significant role in raising global sea level and climate change, the planet, followed closely watching dozens of groups of scientists. Indeed, Greenland continues to melt. But as scientists have found the University of Colorado, Wyoming, and Montana, in the winter on the island of thawing is always accompanied by the freezing of the water, which did not manage to escape into the ocean and

Global warming has brought back to life the most northern lake Earth

Global warming has brought back to life the most northern lake Earth Facts

Kaffeklubben lake, located off the coast of Greenland, came to life again and became home to microscopic algae. This type of algae called diatom disappeared from the northernmost freshwater lake in the world more than two thousand years ago. But now, thanks to warming water microalgae newly seeded Kaffeklubbena.

The lake was formed in about 3.5 thousand years ago, when the retreating glacier formed a relief plain coast of Greenland. With the advent of a new period of cooling diatom population gradually reduced until it

The upper part of the glacier in Greenland is melting rapidly

The upper part of the glacier in Greenland is melting rapidly Facts

As it turned out, the rate of melting of the top layer of the cover. Greenland in July 2012 proved to be the fastest in 30 years. The process involved the thin ice of the outlying coastal and central areas in the 3 km thick. By mid-July is 97% of harp shell subjected to thinning at high temperatures. This phenomenon in the scientific community got its name — the "heat island", or large mass of heated air, place over Greenland from the end of May. The dome is

Greenland may slip into the sea

Greenland may slip into the sea It is interesting

University of Colorado at Boulder said that, like melting snow, sliding off the roofs of houses, the Greenland ice cap may move closer to the ocean, driven by water that collects in the lake directly on the surface of the ice.

Superlednikovoe lakes formed on the surface of a glacier in Greenland.

If this happens, the consequences for coastal residents will stunning, because such a move certainly would raise the water level in the ocean.

What is so alarmed scientists? Summer water produced from the melting of the upper parts of

In Greenland, the sun rose two days early

Sun

20.01.11.V Illuissat town on the west coast of Greenland, the first sunrise after many days of polar night came two days earlier. Residents and scientists are very surprised.

In the town Illuissat polar night ends on 13 January. On this day, you can see the first sunrise. But this year, the sun appears above the horizon in the two days before.

The sun came over the horizon for the whole two days earlier, was to bend the earth's axis. But this phenomenon is drawn to serious consequences. There are rumors that the falling birds and strand sea
