Abstract:

The long-term goal of this study is to determine the processes that control the input of heat into summer leads and the disposition of this heat into lateral melting, bottom melting and heat storage. The objectives of this study are to Determine the albedo of lead surfaces as a function of solar altitude, surface roughness wind speed and fetch, and clouds transmittance. Determine optical properties of leads and their effect on the absorption and penetration of solar radiation. Determine salt and temperature stratification within leads and their dependence on melt rate, airsea heat exchanges and turbulent mixing forced by the wind and ice-ocean velocity difference. Balance the heat and freshwater budgets of leads and assess the effects of atmospheric, ice, and oceanic forcing on the components of the balances.
