Where the Earth’s plates meet, there is evidence of their motion. An expedition of the Research Vessel Polarstern will explore this activity in the Southern Ocean in detail. The major focus of the expedition led by scientists from MARUM is to examine hot vents and cold seeps. This will be the first deployment of the remotely operated vehicle MARUM-QUEST in the Antarctic region.


EU Project

Retrieving Climate History from the Ice

In the Antarctic, European researchers plan to analyse essential climate data from the past 1.5 million years.

Climate Changes of the past: The consortium BE-OI has spent three years combing the Antarctic ice, looking for the ideal site to investigate the climate history of the past 1.5 million years. The results were presented at the conference "European Geosciences Union".


Arctic Ocean

The Transpolar Drift is faltering – and sea ice is now melting before it can leave the nursery

New AWI sea-ice study reveals the extreme scale of sea-ice melting in the Arctic

[02. April 2019] 

The dramatic loss of ice in the Arctic is influencing sea-ice transport across the Arctic Ocean. As experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research report in a new study, today only 20 percent of the sea ice that forms in the shallow Russian marginal seas of the Arctic Ocean actually reaches the Central Arctic, where it joins the Transpolar Drift.


New Study

Colonisation in Slow Motion

A long-term experiment in the Arctic deep sea shows: Sedentary animals in deep waters only colonise new habitats extremely slowly

There is a wide variety of animals living on the Arctic seabed. Attached to rocks, they feed by removing nutrients from the water using filters or tentacles. But it can take decades for these colonies to become established, and they probably don’t achieve their natural diversity until much later. These are the findings of a unique 18-year study by researchers from the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI), which has now been published in the scientific journal “Limnology and Oceanography”.


New Study

Ocean sink for man-made CO2 measured

An international research project has determined the amount of man-made CO2 emissions taken up by the ocean between 1994 and 2007

[15. March 2019] 

Not all of the CO2 generated during the combustion of fossil fuels remains in the atmosphere. The ocean take up considerable quantities of these man-made CO₂ emissions from the atmosphere. Without this sink, the concentration of CO2 in our atmosphere.
