Atmospheric research

Unusual cold spell in the stratosphere creates conditions for severe ozone depletion in the Arctic

AWI researchers measure temperatures of minus 90 degrees Celsius and lower at 20 kilometres altitude

[10. February 2016] 

Unusual weather development in the Arctic leads to ozone depletion. According to the researchers of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, in the past weeks an extreme cold spell in the Arctic stratosphere has created conditions that might cause severe ozone depletion over the Arctic in March – if the next few weeks will not bring a significant warming.


New Study

How stable is the West Antarctic Ice Sheet?

Exceeding critical temperature limits in the Southern Ocean may cause the collapse of ice sheets and a sharp rise in sea levels

[05. February 2016] 

A future warming of the Southern Ocean caused by rising greenhouse gas concentrations in the atmosphere may severely disrupt the stability of the West Antarctic Ice Sheet. The result would be a rise in the global sea level by several metres.


Sea ice physics

Several metre thick ice cocktail beneath coastal Antarctic sea ice

AWI researchers develop new method to detect platelet ice over large distances

[03. February 2016] 

Sea ice physicists of the Alfred Wegener Institute (AWI) have developed a new method that allows them for the first time to efficiently determine the distribution and thickness of what researchers call a sub-ice platelet layer. This several metre thick layer of delicate ice crystals is predominantly found beneath coastal Antarctic sea ice, and at present knowledge about its spatial distribution is very limited.


Permafrost

Researchers measure record erosion on Alaskan riverbank

Itkillik River eats into the thawing riverbank at an average rate of 19 metres per year.

Researchers are working at the yedoma cliff (35 meter high, 680 long) at the Itkillit river in Northern Alaska. Here one can see ice wedges next to frozen sediment pillars. The ice is up to 50 000 years old.
[26. January 2016] 

According to estimates, Alaska's thawing permafrost soils cost the USA several 100 million dollars every decade – primarily because airports, roads, pipelines and settlements require relocation as a result of sinking ground and eroding river banks. An international team of researchers has now measured riverbank erosion rates, which exceed all previous records, along the Itkillik River in Alaska's north. In a stretch of land where the ground contains a particularly large quantity of ice the Itkillik River eats into the river bank at 19...
