Ice Drift in the Weddell Sea (Die Eistrift im Weddelmeer),
Abstract
Factors determining ice drift in the Weddell Sea are analyzed mathematically on the basis of observations made along Siberia and modified to fit local hydrographic conditions. Data are tabulated and graphed on the relation between ice drift and wind with constant wind conditions and increasing ice resistance, surface-drift velocity and friction depth assuming ice resistance to be proportional to the square of the surface velocity, seasonal variations in the wind factor and deviation angle, seasonal variations in the coefficients of ice resistance and wind action, and the relation between wind and ice drift under quasi-stationary conditions. Ice drift in the Weddell Sea is determined by wind action on the ice, the resistance of ice against ice, the depth of the friction layer in the water, and the deflecting force of the earth's rotation. The importance of the wind factor in the Weddell Sea is greater than the open Arctic Ocean since the ice offers a greater surface to the wind. (Author)
