Abstract

Ice Shelf response to Global Ocean temperature change is examined. The thermohaline circulation forced by the mass and energy exchange at the ice-ocean boundary is studied with a two-dimensional model. The melting/freezing rate has been estimated. Different boundary conditions are considered. Maximum melting rate is 2m/y, it is reached at the grounding line. Accumulation of ice takes place at the ice shelf edge with rate on the order of 0.1 m/y. If the underlying water warm by 0.001 °C/y the melting rate would increase to 2.2 m/y and the freezing rate would change by 0.01 m/y. The dimension of the region with supercooled water has been estimated. Introduction Global Change of the temperature could be estimated by means of Ocean temperature chan
