Greenland Ice Sheet Shows Losses in 2019

AWI researchers confirm record ice losses in Greenland in 2019 based on data from the GFZ/NASA satellite mission GRACE Follow-On

The Greenland Ice Sheet recorded a new record loss of mass in 2019. This was the finding of a team of international researchers after evaluating data from satellite observations and modelling data.

MOSAiC expedition reaches the North Pole

During the final leg of the expedition, the research vessel Polarstern reaches the northernmost point on the Earth

At 12:45 pm on 19 August 2020 the German research icebreaker Polarstern reached the North Pole. The ship followed a route to the north of Greenland – and through a region that, in the past, was densely covered with ice, including multiyear ice.

Forecasting low flow conditions for the Elbe and Rhine:

‘Drought stress test’ passed with flying colours!

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

 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.
