Abstract

Abstract

Surface layer parameters over 85°N drifting ice in the Arctic Ocean in summer are estimated using eddy correlation method with observational data of August 20 28,2008 during the 3rd Chinese National Arctic Research Expedition.The results show that the average sensible heat flux,latent heat flux and net radiation are 0.2,1.2 and 9.9 W/m² respectively indicating that the majority of energy received by the underlying surface is used to melt ice and transfer downward,only a small portion for air heating by the way of sensible heat and latent heat.Surface albedo of drifting ice ranges from 0.68 to 0.82 with an average of 0.76.The drag coefficient is 1.65×10^-3 under the near neutral stratification,which is bigger than the estimates obtained by the 1st and 2nd CHINARE.Carbon dioxide flux ranges from －0.09 to +0.06 mg/(m²·s)with an average of －0.015 mg/(m²·s),which means the drifting ice area in the Arctic Ocean in summer is a sink for atmospheric CO₂.
