Research vessel Polarstern expected in Bremerhaven

Antarctic season ends in the home port after half a year

[11. May 2016] 

On Wednesday, 11 May 2016, the research vessel Polarstern is expected back in its home port of Bremerhaven after a good six months of Antarctic expeditions. In the austral summer, the research vessel of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), penetrated into the southern Weddell Sea as far as the Filchner-Ronne Ice Shelf, where oceanographic and biological work was the focus. In addition, the expedition members provided logistical support for a research camp there.

New Ice Age Knowledge

Pacific stores the greenhouse gas carbon dioxide at depths of thousands of metres

Researchers solve one of the great scientific mysteries of the ice ages

[10. May 2016] 

An international team of researchers headed by scientists from the Alfred Wegener Institute has gained new insights into the carbon dioxide exchange between ocean and atmosphere, thus making a significant contribution to solving one of the great scientific mysteries of the ice ages. In the past 800,000 years of climate history, the transitions from interglacials and ice ages were always accompanied by a significant reduction in the carbon dioxide content in the atmosphere. It then fell from 280 to 180 ppm (parts per million). Where this...

Daily up and down of the plankton animals in the sea

New study on the migration behaviour of zooplankton and its diurnal and annual cycles

[04. May 2016] 

A unique series of measurements taken over several years in the Antarctic Ocean provide new findings about the daily vertical migration of zooplankton communities: scientists of the Thünen Institute of Sea Fisheries in Hamburg and the Alfred Wegener Institute in Bremerhaven observed changes during the year and between years. The Antarctic zooplankton is the main source of food for many fish and whale species, including the largest mammal in the world, the blue whale.


Arctic sea ice

The Arctic is facing a decline in sea ice that might equal the negative record of 2012

Data collected by the CryoSat-2 satellite reveal large amounts of thin ice that are unlikely to survive the summer

[21. April 2016] 

Sea ice physicists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), are anticipating that the sea ice cover in the Arctic Ocean this summer may shrink to the record low of 2012. The scientists made this projection after evaluating current satellite data about the thickness of the ice cover. The data show that the arctic sea ice was already extraordinarily thin in the summer of 2015. Comparably little new ice formed during the past winter. Today Dr Marcel Nicolaus, expert on sea ice, has presented...


Technology Transfer

Bionic Lightweight Design researchers of the Alfred Wegener Institute at Hannover Messe 2016

Honeycomb structures as the basic building block for industrial applications presented using holo pyramid

[21. April 2016] 

Researchers of the Alfred Wegener Institute (AWI) will introduce their latest developments in the field of bionic lightweight design at Hannover Messe from 25 to 29 April 2016. Their focus is on the ELiSE lightweight construction method, which uses structures from nature to gain a developmental edge over methods that start from scratch. The industry is currently looking for lightweight reinforcement of complex flat and 3D-components. The AWI researchers have developed and built a holo pyramid that allows them to demonstrate the...
