The Temperature, Melt Water Movement and Density Increase in the Névé of an Alpine Glacier

t The melting-point of ice is lowered by a pressure acting on either one or on both phases, Hence, when a block of ice is compressed adiabatically, it becomes cooled by a melting process to the melting temperature corresponding to the acting hydrostatic pressure. If a large mass of ice, insulated thermally from its surroundings, is initially at oo C., then the temperature at any particular depth is finally the " pressure melting temperature " corresponding to the acting pressure.
