This subproject aims at understanding the hydrodynamic processes which are responsible for basal melt rates and the heat flow in the area of the glacial tongue of the 79°N glacier. This is approached by configuring, using and analyzing idealized but realistic model simulations with a good numerical resolution of the various processes concerning the ice-ocean boundary. In this context, special attention is paid to the understanding of the thermohaline circulation in the approximately 100 km long, 20 km wide and 800 m deep cavern below the ice shelf of the 79°N glacier. The well-known three-equation model for the basal melt rate and the heat flow is to be consistently implemented into the model systems GOTM (1D) and GETM (3D) in order to obtain a modeling tool which enables a quantification of both values. This shall eventually lead to the setup of a realisitic, highly resolved and multiannual 3D model of the 79°N glacier, which will help towards a quantitative analysis of both the melt water flow and the heat flow.
