Kara Sea - northern outskirts
The Kara Sea is the outskirts of the Arctic Ocean. Mostly it is located on the continental shelf. The maximum depth is 620 meters, the average depth is 130 meters, the area is 885 thousand sq. Km. In the northern part, the sea borders on the Arctic basin, in the east it is adjacent to the Laptev Sea, in the west - to the Barents Sea.
The water area is filled with many islands. Most of them are located along the continental coast. The sizes they all have are different. The largest island in the Kara Sea is Novaya Zemlya. The sea has a rather complex outlines and contours of the coastline. Baydaratskaya lip and Ob lip deeply fall into the land. Between them the Yamal Peninsula is far away.
The Kara Sea has an uneven bottom relief. Many different elevations and deep-sea gutters. The eastern and southern parts are smaller than the western and northern ones. One of the deepest areas is located south of Novaya Zemlya. There lay the Newland Hollow. Its depth reaches five hundred meters.In the east of the New Earth, the gutter of St. Anne takes its origin. He goes far into the Arctic pool. More even relief has a central part. The shallowest part is located in the east, near the Yenisei and Ob rivers. The depth here does not exceed fifty meters, and the water is quite desalinated.
Kara Sea almost all year round is under the ice. They reach about four meters in thickness. In the central part there are drifting ice forming a fast ice near the coastline. The tides are not massive, reach from 50 to 80 cm. The surface temperature of the water is close to the freezing temperature and is approximately 1.8 degrees. Areas with greater depth (especially of the gutter) have increased salinity. There is an increase in temperature due to the flow of warm Barents waters. Strong desalination have water in the mouths of large rivers.
The Kara Sea, whose photos are amazingly beautiful, is the coldest in Russia. In summer, the water surface warms up to 6 degrees. Storms and fogs are frequent here. There are two stable currents slowly moving the water mass counterclockwise. They are located in the northeast and southwest.
Flora and fauna
The rapid development of life due to the harsh climate, cold water and ice shell is limited here. The composition of the animal world in these waters is several times leaner than in the Barents Sea. However, life is present. Flora are several species of benthic plants. The main food of cetaceans in these waters is zooplankton. The Kara Sea is rich in invertebrates and fish. The latter are represented by 54 species. Among mammals live walrus, beluga whale, seal, sea hare. Whales are represented by whales. Fishery crafts are organized only in bays, lower reaches of rivers and gulfs - there is less ice cover.
Life on the islands
Numerous islands have been chosen by numerous bird colonies (guagar, murre).
