Rivers

Forecasting low flow conditions for the Elbe and Rhine:

‘Drought stress test’ passed with flying colours!

[06. August 2020] 

Using global climate data, AWI researchers can now forecast low water levels in German rivers up to three months in advance – even in extreme cases such as the summer of 2018


Climate History

How the seafloor of the Antarctic Ocean is changing – and the climate is following suit

Experts have reconstructed the depth of the Southern Ocean at key phases in the last 34 million years of the Antarctic’s climate history

[04. August 2020] 

 A team of international experts, led by geophysicists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), has shed new light on nine pivotal intervals in the climate history of the Antarctic, spread over 34 million years, by reconstructing the depth of the Southern Ocean in each one.


MOSAiC-Expedition

Time to Say Goodbye

The MOSAiC floe’s days are numbered, but Polarstern will continue the expedition further north

[31. July 2020] 

After exactly 300 days of drifting with the MOSAiC floe, the international team around Expedition Leader Markus Rex on Wednesday, 29 July 2020, started the dismantling of the research camp and evacuation of the floe. Just one day later the floe finally broke into several fragments. After accompanying the floe on its journey for ten months, the team will now shift its focus to the last remaining puzzle piece in the annual cycle of Arctic sea ice: the start of the ice formation process.


Sea Ice

Sea-ice extent in the Arctic at a historical low

Especially low values off the Siberian coast, Northeast Passage ice-free since July

[27. July 2020] 

The Arctic sea-ice extent is the lowest it’s ever been in July since the beginning of satellite observation. The sea-ice retreat is especially pronounced off the Siberian coast, as a result of which the Northeast Passage (also referred to as the Northern Sea Route) was ice-free by mid-July.

Climate change is impacting the spread of invasive animal species

The Asian shore crab as an example of invasive species successfully spreading to the North Sea and Baltic

[22. July 2020] 

What factors influence the spread of invasive animal species in our oceans? This question was the focus for a team of experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), Bangor University (Wales, UK), and the University of Greifswald’s Zoological Institute and Museum in the context of the DFG-sponsored Research Training Group 2010 RESPONSE (Biological Responses to Novel and Changing Environments). The results of their study have just been released in the journal “Ecography”.
