Greenland Ice-Core Project (EastGRIP) is a drilling project aiming to retrieve a deep ice core in North-East Greenland. The drilling site is on a dynamically active location, where the surface flow velocities [...] previous deep ice core sites. It is located at the onset of the largest ice stream in Greenland (NEGIS - North-East Greenland ice stream). Ice streams are not very well represented in large scale ice sheet models [...] if not prescribed by inversion methods based on observed surface velocities. Their contribution to sea level projections is thus not very well constrained and a source of uncertainty. Three regimes can

In connection with current plans for a massive expansion of wind farms in offshore areas of the North Sea, the idea emerged to combine these with the installation of extensive mariculture for bivalves and [...] interaction between physical offshore processes and man-made structures in areas of the German North Sea territory where mariculture has potential, the conditions for possible combination of mariculture [...] ment force experiments that algae were capable of resisting the high-energy environment of the North Sea.
