East Siberian Sea runoff into the East Siberian Sea is relatively small at about 250 km/year that makes only 10% of the total runoff in all the Arctic seas of Russia. The largest contribution is from the Kolyma River at 132 km, followed by the Indigirka River at 59 km. Most runoff (90%) occurs in summer; it is concentrated near the coast, owing to the weak river currents, and therefore does not significantly affect the sea hydrology. The water exchange between the neighboring seas is as follows. The annual outflow to the Laptev Sea, Chukchi Sea and Arctic Ocean is 3,240, 6,600 and
Weddell Sea Bottom Water region of sinking, it eventually mixes with the warmer and more saline water above to form AABW. Along the Scotia Ridge-Cape Norvegia section, potential temperature values at depths greater than range from -0.94 to -0.63 °C, while salinity values range from 34.639 to 34.652 psu. The northern limit of the core of Weddell Sea Bottom Water lies against the southern edge of the Scotia Ridge, suggesting that the circulation and property distributions are strongly influenced by bathymetry. The transport of Weddell Sea Bottom Water out of the Weddell Sea represents the outflow of newly formed bottom water plus entrained bottom
