"Meet the members"

German Association for Marine Technology at the AWI

Bremerhaven-based members of the Association visit the Research Institute

[20. June 2017] 

The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) welcomed members of the Association for Marine Technology (GMT). The AWI is itself a member of the association for offshore and marine technology, which, among other things, is committed to the transfer of knowledge and technology between science and industry in the marine-maritime field.

How the climate can rapidly change at tipping points

A new study shows: Gradual changes in the atmospheric CO2 concentration can induce abrupt climate changes

During the last glacial period, within only a few decades the influence of atmospheric CO2 on the North Atlantic circulation resulted in temperature increases of up to 10 degrees Celsius in Greenland – as indicated by new climate calculations from researchers at the Alfred Wegener Institute and the University of Cardiff.

How the Arctic Ocean Became Saline

AWI researchers model climate changes caused by the submersion of the Greenland-Scotland Ridge

The Arctic Ocean was once a gigantic freshwater lake. Only after the land bridge between Greenland and Scotland had submerged far enough did vast quantities of salt water pour in from the Atlantic. With the help of a climate model, researchers from the Alfred Wegener Institute have demonstrated how this process took place, allowing us for the first time to understand more accurately how Atlantic circulation as we know it today came about. The results of the study have now been published in the journal Nature Communications.

Joint press release from the University of Oldenburg and the AWI

Why do Antarctic krill stocks fluctuate?

Climatic factors play a lesser role than previously thought

[05. June 2017] 

It is only six centimetres long, but it plays a major role in the Antarctic ecosystem: the small crustacean Euphausia superba (Antarctic krill). It's one of the world's most abundant species and the central diet of a number of animals in the Southern Ocean. For a long time, scientists have been puzzled why the size of krill stocks fluctuates so widely. In a new study headed by Prof. Bernd Blasius and Prof. Bettina Meyer, a group of scientists from the University of Oldenburg's Institute for Chemistry and Biology of the Marine Environment (ICBM) and the...


Study in Nature Communications

Geoscientific evidence for subglacial lakes

Meltwater lakes under the Antarctic Ice Sheet accelerated glacial retreat in the Earth’s past

[01. June 2017] 

During the last glacial period – when the ice in the Antarctic was far thicker and extended further offshore than it does today – it has been speculated that subglacial lakes existed beneath it. An international team of researchers has now successfully sampled the metre-thick sediment layers left behind by these lakes contemporary on the seafloor. This is the outcome of a study by Gerhard Kuhn and colleagues, which was published today in the journal Nature Communications.
