The area of the sea is 913,000 km²; most of the time it is covered with ice. 70% of it is no deeper than 50m, the deepest point being 155m. The coast is mostly flat in the West (up to the mouth of the Kolyma), mountainous in the East. Average temperatures (air) is 0°C to 2°C (4°C in the South) in the summer, reaching -30°C in the winter.
The sea was navigated by Russian sea-farers, moving from one river mouth to another in their kochs as early as the 17th century. In 1648Semyon Dezhnev and Fedot Alekseev sailed the coast from the Kolyma to river Anadyr and Bering Strait. Systematic exploration and mapping of the sea and its coasts was carried out by a series of expeditions in 1735-42, 1820-24, 1822, 1909, 1911-14.
It adjoins the Laptev Sea to the west, the Chuckchi Sea to the east and the Arctic Ocean proper to the north.
The freshwater input of the Kolyma River is of prime hydrographic significance to the EastSiberian Shelf Sea.
The Adriatic Sea is considered the source of cold and less saline EMDW, which is formed in the winter in the Ionian Sea by the mixing of deep and cold Adriatic water (that enters the Ionian via Otranto Strait) with transformed LIW and, to a lesser extent, by mixing with deep Cretan waters.
In the Russian Far East, where decades of poaching have diminished the Siberian tigers' numbers to an estimated 500, Miquelle and fellow Wildlife Conservation Society biologist John Goodrich are waging a lonely battle to keep the largest member of the cat family from disappearing.
Though the Siberian tigers' future is far from certain, Miquelle takes solace in the fact that the animals' numbers have stabilized since the mid-1990s, when poaching was claiming as many as 80 tigers each year.
Siberian tiger populations began plummeting between 1910 and 1940, when the animals were hunted as game or regarded as pests and culled.
