The Siberian Sea

 

The East Siberian Sea, Russian: Vostochno-sibirskoye More, a portion of the Arctic Ocean between the New Siberian Islands (west) and the island of Wrangel (east).


Covering a surface of 936 thousand square kilometers, East Siberian Sea is an insignificant ocean in the Arctic Ocean, located on the northern coast of eastern Siberia.


Because it is open to the Arctic Ocean to its north, major Gulfs of the East Siberian Sea such as the Kollima Gulf, the Kollima Channel, and Chaunskaya Bay are located at its southern limits.

 

The East Siberian Sea is located between Arctic Seaboard in the north, Siberian Seaboard to the south, the Siberian coast to the west, Cape Billings, near Chukotka, and the island of Wrangel to the east.


The area of drainage basin for the East Siberian Sea is 1,342 million km2, and major rivers include Alazeya, Chukochya, Chaun, Indigirka, Kolyma, Pegtymel, and Raucoua rivers.


Ships traveling through the East Siberian Sea, bordered on the west by the Laptev Sea and New Siberian Islands, and on the east by the Chukchi Sea and Wrangel Islands, are at greatest risk for collisions, ship sinkings, or groundings, mostly due to the harsher ice conditions, such as earlier, faster accumulations of ice during late summer.

 

Northeast of the New Siberian Islands, sea ice remaining in this region is scarce.


In this image from 15 June, floating sea ice is attached along the shores of Eastern Siberia, stretching northward toward the New Siberian Islands.


These images reveal part of the coastline of eastern Siberia and the New Siberian Islands, about 1,900 kilometers (1,200 miles) northwest of Alaska.

 

The Siberian coastline is largely flat and smooth, with gently rising hills, whereas the eastern coastline is fairly mountainous, with precipitous peaks.


Most runoff (90%), occurs during the summer; this is concentrated close to Siberian coastline, due to the weak currents in the rivers, and thus does not affect sea water hydrology much.

 

The observed rise in the salinity at the surface of the Wilkitsky Strait and in western parts of the East-Siberian Sea provides evidence for a westernward shift in the Ob-Yenisei plume, and the associated decline of the transport of freshwater from the Kara Sea into the Laptev Sea.


As a consequence, the Ob-Yenisei plume generally occupies a wide swath of the southeast part of the Kara Sea near the Vilkitsky, and is spreading across these areas into the western part of the East-Siberian Sea, which is registered in the in situ measurements of salinity.

 

All five of the northern seas on the northern sea route are relatively safe in comparison with the other main navigation areas.


Even in the summer, 50% ice coverage remains, a sharp contrast with, say, the Barents Sea, which is entirely ice-free in summer.
