Studies of sea-ice motion in the Laptev Sea with the use of satellite remote sensing and numerical modelling

Abstract

Seasonal and interannual variability of ice drifi in the Laptev sert and ice exchange with the Arctic Ocean have been investigated using remote sensing data, a large-scale dynamic-thermodynamic numerical sea ice model and . During the period 1979 -1995 seathe Laptev Sea with maximum export occuring in F&,nuuy and minimum in August. The average winter ice outfIow during this period was equal to 482700 km2. Estimates of ice exchange between the northern and southern parts of the Laptev Sea during the period 1936 to 1996 exhibited 8 strong interannual variability, but did not reveal sigaificatlt trends.
