Sponges: They are considered to be one of the most primitive forms of animal life, because they have neither locomotion organs nor a nervous system. A team around deep-sea scientist Antje Boetius has now discovered that sponges leave trails on the sea floor in the Arctic deep sea. They conclude that the animals might move actively - even if only a few centimetres per year. They are now publishing these unique findings in the journal Current Biology.

The High-Tech Forum has published its key recommendations for the future innovation strategy in Germany. Prof. Dr. Antje Boetius, Director of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research is a member of the central committee that advises the Federal Government on implementing the High-Tech Strategy 2025 and contributed to the report on the results. The Forum urges promoting and demanding greater courage and implementation strength in the service of the Sustainable Development Goals. It maintains that it is important to…

The German polar and marine research community pays him high respect and tribute. Prof. Dr Jörn Thiede, founding director of today's GEOMAR Helmholtz Centre for Ocean Research Kiel and long-time director of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research in Bremerhaven, celebrates his 80th birthday today. Due to Corona, instead of a large festive event with many guests, many companions sent him their birthday wishes in personal video messages.

Stormy weather and strict hygiene regulations put the science crew to the test. After a delay of almost two days due to weather conditions and several days of scheduled quarantine, the captain of the HEINCKE gave the command "cast off" on Thursday morning and set course for Helgoland. The research team of the "North Sea Wrecks" project collected samples around the wreck of the warship SMS MAINZ off the North Sea island. They will be used to investigate the extent to which the ship from the First World War, which was sunk together with its ammunition,…

Scientists of the JPI Oceans project “MiningImpact” are embarking on a 6-week expedition to the Clarion-Clipperton Fracture Zone (CCZ) in the Pacific. Their goal is to carry out independent scientific monitoring of the test of a pre-prototype nodule collector machine conducted in parallel from a second vessel by the Belgian company Global Sea Mineral Resources (GSR). “MiningImpact” fully adheres to good scientific practice and all data will be made publicly available. The findings of this integrated impact analysis will be transferred into…

Michael Gutsche has given the AWI three large-format photos on permanent loan. The photographer took the impressive nature photos during the Arctic expedition "MOSAiC". Together with AWI director Antje Boetius, Gutsche unveiled the photos at the institute's location in Bremerhaven. There they now adorn the walls in the foyer of building E and in the entrance area of buildings A / B / C. The images show, among other things, how quickly the weather conditions in the Arctic can change and how fragile this ecosystem is.

Every year, ten international scholarship holders from all corners of the globe come to the Alfred Wegener Institute’s two island-based sites. The POGO-Nippon Foundation Centre of Excellence trains them to become oceanography experts. 

MOSAiC expedition leader Markus Rex informed the Arctic Council about the Arctic drift expedition and presented the first results. The Arctic Council is the leading cross-national forum for the Arctic. Germany has observer status in the Arctic Council and is represented by the Foreign Office. Senior Arctic Official Chair, Ambassador Einar Gunnarsson, thanked Markus Rex for his presentation and congratulated Germany and all other nations involved in this historic expedition.
 

In the future, droughts could be even more severe than those that struck parts of Germany in 2018. An analysis of climate data from the last millennium shows that several factors have to coincide to produce a megadrought: not only rising temperatures, but also the amount of solar radiation, as well as certain meteorological and ocean-circulation conditions in the North Atlantic, like those expected to arise in the future. A group of researchers led by the Alfred Wegener Institute have just released their findings in the journal Communications Earth &…

Roughly two weeks ago, a massive iceberg calved from the Antarctic Ice Sheet. As the only research vessel nearby, the Polarstern took the opportunity to enter the area between the iceberg and the Brunt Ice Shelf. The first images from the seafloor reveal an amazing level of biodiversity in a region that was covered by thick ice for decades. The sediment samples gathered are expected to provide more detailed insights into the ecosystem, while a geochemical analysis of the water samples collected will allow conclusions to be drawn regarding the nutrient…
