Climate change threatens Arctic polar cod stocks

Researchers fear significant consequences of rising temperatures and sea ice retreat for the most important fish in the Arctic Ocean

The Arctic polar cod Boreogadus saida
[09. August 2023]  Arctic cod is the most abundant fish in the Arctic Ocean. It is an important food source for Arctic marine mammals and plays an important role in the self-sufficiency of the Inuit. An international study team, including researchers from the Alfred Wegener Institute, has now evaluated the most important scientific work on Arctic cod of the past decades. The conclusion: Above all, the already advanced decline in arctic sea ice cover as a result of man-made climate change could have a significant impact on the future distribution of the species. The study was published in the journal Elementa: Science of the Anthropocene.

Eyewitnesses to Arctic Change

AWI Director Antje Boetius leads Polarstern expedition to the Central Arctic

[01. August 2023]  On Thursday, 3 August 2023, the research vessel Polarstern is scheduled to set off from Tromsø, Norway, towards the North Pole. For two months, a good fifty scientific expedition participants will explore the Arctic in transition as sea ice extent reaches its annual minimum in September. They will explore the biology, chemistry and physics of sea ice as well as the effects of sea ice retreat on the entire ocean system from the surface to the deep sea. Eleven years ago, Antje Boetius was part of the largest ever sea ice minumum in the Arctic and its consequences for life in the deep sea. Now she is returning with her team to compare the state of the Arctic today - also with the data from the MOSAiC expedition 2019/20.

[27. June 2023]  The project MonitorShrimp, which is making considerable strides in improving animal welfare and performance in the context of shrimp farming, is the outcome of a consortium combining the AWI, Oceanloop and Sander Holding. The participating researchers have developed a computer vision system that allows early detection and monitoring of the tiny creatures’ growth, population size, mortality and stress.

20 Years AWIPEV: the French – German Arctic Research Base

Anniversary event at the French Embassy in Berlin

Blue House of AWIPEV in Ny-Ålesund, Svalbard during polar night.
[08. June 2023]  A successful cooperation in international polar research celebrates its 20th anniversary. In 2003, the German Alfred Wegener Institute (AWI) and the French Polar Research Institute Paul-Émile Victor (IPEV) merged their stations Koldewey and Rabot on Svalbard to form the AWIPEV base. Since then, scientists from both countries have jointly been conducting research there on the effects of climate change in the Arctic as part of the Ny-Ålesund research station coordinated by Norway. The anniversary of the successful partnership will be celebrated on June 14, 2023, at a festive event at the French Embassy in Berlin.

Working Together to Bring High Tech Below the Waves

Kick-off meeting for MUSE infrastructure from 23 to 25 May at the AWI in Bremerhaven

First on sea deployment of the AUV
[23. May 2023]  Over the next seven years, the three largest marine research institutes in the Helmholtz Association – the AWI, GEOMAR and Hereon – will pool resources to develop their marine technologies. Their goal: to more quickly and efficiently develop underwater robotic systems, ensuring that research can keep pace with the impacts of climate change, biodiversity loss and pollution.
