Long-term data reveal: The deep Greenland Sea is warming faster than the World Ocean

[24. September 2013] 

Recent warming of the Greenland Sea Deep Water is about ten times higher than warming rates estimated for the global ocean. Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research recently published these findings in the journal Geophysical Research Letters. For their study, they analysed temperature data from 1950 to 2010 in the abyssal Greenland Sea, which is an ocean area located just to the south of the Arctic Ocean.

Current sea ice development in the Arctic: edge of the pack ice retreats significantly, but the area is greater than in 2012

[19. September 2013] 

The annual minimum sea ice cover in the Arctic Ocean in September is on average around 5.1 million square kilometres this year, and is thus some 50 percent above the previous negative record of 3.4 million square kilometres recorded in 2012. “This figure does not signal a reversal in the trend, however”, is the joint conclusion drawn by sea ice physicist Marcel Nicolaus from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), and Lars Kaleschke from the University of Hamburg, KlimaCampus (Climate Campus).

Surprising underwater-sounds: Humpback whales also spend their winter in Antarctica

[07. September 2013] 

Biologists and physicists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, found out that not all of the Southern Hemisphere humpback whales (Megaptera novaeangliae) migrate towards the equator at the end of the Antarctic summer. Part of the population remains in Antarctic waters throughout the entire winter. The scientists report this in a current issue of scientific journal PLOS ONE. This surprising discovery based on underwater recordings from the Antarctic acoustic observatory PALAOA. It is located near the research base Neumayer Station III on the ice shelf and regularly records underwater sounds of humpback whales even in the austral winter months.

Scientists analyse the extent of ocean acidification

[25. August 2013] 

Ocean acidification could change the ecosystems of our seas even by the end of this century. Biologists at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have therefore assessed the extent of this ominous change for the first time. In a new study they compiled and analysed all available data on the reaction of marine animals to ocean acidification. The scientists found that whilst the majority of animal species investigated are affected by ocean acidification, the respective impacts are very specific. The AWI-researchers present their results as an Advance Online Publication on Sunday 25 August 2013 in Nature Climate Change.
