The main components of an ice sheet model are the equations for:(1)the momentum balance(typically Stokes equations or their approximations)and(2)the ice thi
Many ice-sheets contain ice that is at the melting temperature and contains pore water.We examine a model to determine the heat/water content of such ice,an
