SEA ICES

Them are called nunataks. “Nunatak” - eskimo word. In the scientific literature this word fell because of famous polar Swedish researcher Nils Nordenskjold. The same “semi-cover” type of ice formation includes foothill glaciers. Frequently the glacier, which is descended from the mountains along the valley, reaches their feet and it leaves by wide blades into the zone of melting (ablation) in the plain (this type of glaciers is called still Alaska) or even in the shelf or into the lakes (Patagonian type). Foothill glaciers - their some most spectacular and most beautiful. They are encountered in Alaska, on the north of North America, in Patagonia, in the extreme south of South America, on Spitsbergen. Is most widely known the foothill glacier Of in Alaska.

In order to learn the way of drifting ices, great Norwegian traveller Frithjof Nansen decided to drift aboard his ship “Frahm” together with them. This daring expedition lasted entire three years (1893-1896 yr). After allowing “Frahm” to freeze in into drifting pack ice, Nansen expected to move with it into the region of the north pole, and to then leave ship and to continue way on the canine harnesses and on skis. However, drift passed south, than it was assumed, and Nansen's attempt to reach pole on skis was not crowned with success. After passing more than 3000 miles from the Novosibirsk islands to the West Coast of Spitsbergen, “Frahm” gathered unique information about drifting ices and influence on their motion of period of Earth's rotation on its axis
