[VI1JWV: New Data on Sea-Ice Albedo in the Laplev and Barents Seas
63
Thus the investigations, performed in summer 1993 in the Barents and Laptev Seas, as a
whole, have confirmed present data on reflective ability of the basic surface types of sea ice
cover in summer-autumn period. So, the constancy of puddles albedo of depth from 5 cm up
to 35-50 cm was found, which had not been described till now, and which was caused by
multiple re-reflection of incoming short-wave solar radiation between the upper and lower
borders of pUddles. The performed observations and processes modeling of carrying of solar
radiation in puddles and snow-ice cover, based on their results, will allow to describe processes
of formation and destruction of sea ice cover within spring-summer-autumn period more clear
when there are its most radical changes.

The author is sincerely grateful to organizers of Transdrift-IV expedition for the possibility to
study the ice cover of the Laptev and Barents Seas. The author is also thankful to Dr. V.
Aleksandrov (State Research Center of the Russian Federation -Arctic and Antarctic Research
Institute) for his contribution to the field measurements performance.
