Arctic Sea Ice

Low sea-ice cover in the Arctic

Second-lowest September minimum since observations

[13. September 2019] 

The sea-ice extent in the Arctic is nearing its annual minimum at the end of the melt season in September. Only circa 3.9 million square kilometres of the Arctic Ocean are covered by sea ice any more, according to researchers from the Alfred Wegener Institute and the University of Bremen. This is only the second time that the annual minimum has dropped below four million square kilometres since satellite measurements began in 1979.


Climate Modelling

New Climate Model for the IPCC

AWI climate model part of the basis for the IPCC Assessment Report for the first time

[04. September 2019] 

Researchers from the Alfred Wegener Institute now, for the first time, feed the results from their global models directly into the Intergovernmental Panel on Climate Change database. The data is particularly interesting because the underlying model, developed at the AWI, depicts the sea ice and the oceans with far greater definition than conventional methods. The results are used by climate scientists and stakeholders around the globe to determine the effects of climate change on humans and the environment.


AWI-Hausgarten

Anniversary in the far north

20 years of long-term ecological research in the deep Arctic Ocean

[29. August 2019] 

20 years ago, scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) laid the “foundation stone” for a unique long-term observatory in the partly ice-covered Fram Strait between Greenland and Svalbard, which they call their HAUSGARTEN. The deep-sea observatory is the first, and still the only one of its kind for year-round physical, chemical and biological observations in a polar region. Here researchers investigate how a polar marine ecosystem alters in a period of global change. 


Scientific study

Microplastic drifting down with the snow

In the Alps and the Arctic, experts confirm the presence of plastic in snow

[14. August 2019] 

Over the past several years, microplastic particles have repeatedly been detected in seawater, drinking water, and even in animals. But these minute particles are also transported by the atmosphere and subsequently washed out of the air, especially by snow – this was demonstrated in a study conducted by experts at the Alfred Wegener Institute.


Expedition

Polarstern departs for the Arctic

Conducting research at the long-term deep-sea observatory Hausgarten

[07. August 2019] 

On the evening of 10 August 2019, the research ship Polarstern will leave her homeport in Bremerhaven. The purpose of the expedition is to conduct studies at a major long-term monitoring station in the Arctic: the AWI’s Hausgarten observatory in the Fram Strait.
