As regards salinity, the thawing of ice and the inflow of fresh river water might have resulted in a layer of fresh water 53 inches (135 cm) thick. In winter the salinity in the southeastern part of the sea is 2025 parts per thousand, in the northern part up to 34, and in summer the salinity falls to 510 parts per thousand in the southeast and 3032 in the north. Air temperature below 32 F (0 C) occurs in the north during about 11 months and in the south 9 months. The average temperature in January is -24 to -29 F (-31 to -34 C), the minimum about -58 F (-50 C). In July the average temperature in the north is just above the freezing point, in the south about 43 F (6 C), with a maximum of 50 F (10 C). In the winter the temperature of the water under the ice is 30.6 F (-0.8 C) in the southeast and 28.8 F (-1.8 C) in the north; in the deep regions it is from 29.1 to 28.9 F (-1.6 to -1.7 C). f part
