is the case in many other time series around the world. This facilitates a unique insight in the North Sea ecosystem but also means a lot of work on the ships as well as in our laboratories, where the different

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. The concentration of mussel larvae in the water column decreased offshore and resulted in a low

investigations conducted by the AWI showed that the basic biotic conditions in many parts of the German North Sea are given for the cultivation of various candidates under offshore conditions, such as seaweeds [...] analysis conducted by the AWI showed that farmed or wild mussels from the intertidal areas in the Wadden Sea suffer under high infestations of macro parasites such as copepods (see Fig. 3), trematods (see Fig

The maps cover commercial mussel beds in the Wadden Sea, an oyster farm, land-based recirculation systems as well as present [...] created. These maps show the current mariculture sites in the German part of the southern North Sea. In order to create those maps the geographic information system ArcGIS has been used. ArcGIS software

Due to the provision of fixed infrastructure [...] growing marine organisms in the open sea, but also to counterbalance the continuing scarce seed mussel supply, which influences the mussel fishery sector in the Wadden Sea.

To answer this question we needed the bathymetry at the shelf edge of 79th glaciers As ships cannot access this area, we planned a 36 km seismic cross line on the sea ice. This [...] allowed us to collect CTD profiles (Conductivity, Temperature, Density) of the seawater. To get reliable sea ice conditions we left early, in April 2016. Conditions were cold, -25°C to -40°C causing hardware
