UNDER A SHELF GLACIER

The reaction of a shelf glacier to possible changes 
in the global temperature of the ocean is studied. A two-dimensional 
model of the thermohaline circulation of water under a shelf glacier 
that is determined by heat and mass transfer on the boundary of the 
ocean and the glacier is considered. The velocity of the front of 
the phase transition "glacier-water" is evaluated, and the effect 
of different boundary conditions on the velocity is studied. 
Melting/building-up of ice on the lower boundary of a shelf glacier 
is an integral response to a change in the temperature of the water, 
and it can be a characteristic of the global change in the temperature 
of the ocean.
