Abstract : Isostatic phenomena in drifting ice floes are caused by the uneven thawing and accretion of ice, by runoff of melt water, snow accumulation and other causes. The tendency of ice toward isostatic equilibrium is manifested not only in the variation in its settling general for the ice field but also in the plastic deformations of ice, i.e. in the vertical displacements of one part of the field relative to another, associated with local disruptions in the isostatic equilibrium. These disruptions develop continuously as a result, equilibrium is found only as a whole for the entire ice field or its large parts. Involving supplemental data, the authors show the possible application of an analysis of isostasy to certain ice calculations.
