The site preparation for the Technical Centre starts in mid-September. The new building on Klußmannstraße is part of the AWI campus in the 'Handelshafen' area. Anyone interested can find out more on-site on Sunday, 16 September.
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.
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.
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.
In the future, climate change could abruptly increase the amount of methane released by lakes in the permafrost regions of the Arctic. 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 matter in the thawed sediments may strongly increase the emissions of the greenhouse gas methane.
