Subprojects

In order to better understand the interactions between the Greenland Ice Sheet and its surrounding ocean, the project partners are applying a large number of different observational techniques and modelling studies. Within GROCE, scientists of various disciplines have joined effort to combine their knowledge about this complicated system to answer the most pressing research questions. In order to tackle this ambitious task,  the project has been separated into 11 subprojects, each with its own topic and focus, which are however strongly interconnected: 

Subproject 1 supports the communication between different scientific tasks, organizes the presence and visibility of the project on conferences and to the general public ....

Subproject 2 investigates the influence of warm Atlantic water intrusions on basal melt within the cavity of the 79°N glacier, a process regarded as a dominant factor for its ongoing destabilization.

Subproject 3 utilizes a numerical model to determine the effect of tidal motion on the movement of the grounding line of the 79°N glacier, which separates the floating ice tongue from the grounded continental ice sheet.

Subproject 4 aims to determine the fraction & distribution of basal meltwater, and changes thereof, using an analysis of Helium and Neon Isotopes in water samples taken close to the 79°N glacier.

Subproject 5 aims at a better understanding of the processes governing the evolution of peripheral glaciers, using a particular parameterization of ice-ocean interaction in an existing glacier model.

Subproject 6 aims to determine the glacial-isostatic adjustment (GIA) of the Earth's crust in North-East Greenland.

Subproject 7 aims to determine the spatio-temporal variability of the grounding line of the 79°N glacier, and the areas of supra-glacial metwater on the glacier's surface.

Subproject 8 investigates the interaction between the atmosphere and the 79°N glacier's surface in order to determine the system's dynamics and the climatic mass balance of the glacier.

Subproject 9 investigates the hydrodynamic processes responsible for the observed basal melt rates and heat fluxes associated to the 79°N glacier's floating ice tongue, using idealized as well as realistic numerical simulations.

Subproject 10 merges the geodetic and oceanographic data in order to better understand the impact of a changing climate on ocean physical properties and dynamics.

Subproject 11 uses Langrangian modelling to investigate ocean currents around Greenland, with a focus on their feedbacks with enhanced freshwater input by Greenland's melting glaciers.
