Return to Bremerhaven: The research vessel Polarstern returns with new findings from the Central Arctic during the 2012 ice minimum

[05. October 2012] 

Polarstern is expected back from the Central Arctic expedition “IceArc“ in Bremerhaven on 8 October 2012 after a good two months. 54 scientists and technicians from twelve different countries conducted research on the retreat of the sea ice and the consequences for the Arctic Ocean and its ecosystems over a period of two months in the High North.

The chemical memory of seawater: scientists examine the biomolecules dissolved in the ocean and read them like a history book of the sea

[27. September 2012] 

Water does not forget, says Prof. Boris Koch, a chemist at the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association. Irrespective of what happens in the sea: whether the sun shines, algae bloom or a school of dolphins swims through a marine area – everything and everyone leaves biomolecular tracks. With the help of a combination of new techniques, Boris Koch and colleagues can now identify and retrace some of these.

Research online: new measuring technique enables innovative observations of the North Sea

[25. September 2012] 

An underwater data node, developed by the Institute of Coastal Research at the Helmholtz-Zentrum Geesthacht and the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, functions as an underwater “data plug” at the sea bed. With connected sensors, it is possible to carry out real-time year-round measurements of water temperatures, algae concentrations and the sea floor.

Fifty years of sampling at Heligoland Roads: Marine data for climate modelers, biologists and structural engineers

[17. September 2012] 

“Data from the Heligoland Roads marine sampling site are of immense importance for sustainability considerations of future generations.” With these words the Parliamentary State Secretary to the German Federal Minister of Education and Research, Dr. Helge Braun took celebratory the water sample marking the 50th Anniversary of the establishment of the Heligoland Roads sampling series.

Witnesses of glacial melting: marine researchers examine the influence of the rapid rise in freshwater inflow on marine algae along the west coast of Greenland

[10. August 2012] 

This year Greenland is experiencing one of the warmest summers in its recent history. This heat wave has meant that an international research team is in the unique position of being able to collect important climate data from the changing Arctic. Until today German and US scientists on board the research ship MARIA S. MERIAN have been studying the extent to which the strong inflow of meltwater into the fjords along Greenland’s west coast are altering the chemical composition of the seawater and thus the living conditions for algae and other microorganisms.
