HEAT AND MASS BALANCE AT THE SURFACE OF THE WARD HUNT ICE SHELF, 1960
Abstract
This report contains results of a micro study of heat balance and ablation at the surface of the Ice Shelf. It gives sources and percentages of heat for ablation, and percentages of heat used by convection, conduction, melting and evaporation. Also, seasonal precipitation is interpreted, yearly snow accumulation is averaged, progression of melt through the summer is outlined, and a mechanism of ridge-trough migration is described. From morphological evidence and a statistical analysis of trough-ridge profiles, a tentative conclusion is made that three E-W zones exist across the Shelf, possibly formed by accretion of pack ice with parallel pressure ridges added seawards.
