Simulation of near-bottom water warming in the Laptev Sea
Abstract A coupled ice-ocean model forced by atmospheric reanalysis data is used to examine a change in the bottom layer of the Laptev Sea on a scale of several decades. The model shows that since the mid-1980s there has been a warming of bottom waters in the shelf region. Analyzing values of bottom...
