Coastal erosion in the Arctic intensifies global warming
The loss of arctic permafrost deposits by coastal erosion could amplify climate warming via the greenhouse effect. A study using sediment samples from the Sea of Okhotsk on the eastern coast of Russia led by AWI researchers revealed that the loss of Arctic permafrost at the end of the last glacial period led to repeated sudden increases in the carbon dioxide concentration in the atmosphere.

Kidnapping in the Antarctic animal world?
Pteropods or sea snails, also called sea angels, produce chemical deterrents to ward off predators, and some species of amphipods take advantage of this by carrying pteropods piggyback to gain protection from their voracious predators. There is no recognisable benefit for the pteropod. On the contrary they starve: captured between the amphipod’s legs they are unable to feed. Biologists working with Dr Charlotte Havermans at the Alfred Wegener Institute have investigated this phenomenon as part of a cooperation project with the University of Bremen. In…

Prof. Antje Boetius receives the 2018 German Environmental Award
The 2018 German Environmental Award goes to Antje Boetius and a team of wastewater experts from Leipzig. The Director of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) is glad to see the deep seas and polar regions, the last great expanses of unspoiled nature, attracting more attention. Helmholtz President Prof. Otmar D. Wiestler has praised Boetius as a strong advocate for preserving our oceans.

How Arctic lakes are accelerating climate change
In the future, climate change could abruptly increase the amount of methane released by lakes in the permafrost regions of the Arctic. The explanation: because of thawing permafrost, these lakes are expanding, and below them the water is gnawing away deeper and deeper into the previously frozen soil where microbes now can produce methane. An international research team, including experts from the Alfred Wegener Institute, has now determined that the rapid thaw under lakes has been neglected in models so far and that bacterial decomposition of organic…

Questioning conventional understanding of antifreeze proteins
Scientists have discovered that an ice-binding protein (fcIBP) from the sea ice microalga does not fit in the conventional classification of ice-binding proteins, suggesting unknown mechanisms behind its antifreeze property. This finding could lead to a broader application of the antifreeze protein in food and medical industries.

Ten scholarship holders in oceanography honoured
Today ten scholarship holders from around the globe presented their final papers at the Wissenschaftsforum conference centre in Berlin as part of the Centre of Excellence in Observational Oceanography. For the past ten months, all have been engaged in a training programme addressing all oceanographic disciplines at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). To close this important chapter of their lives with due pomp and splendour, there will be a festive graduation ceremony. Representatives of the programme’s…
