Topping-out ceremony for the new AWI building for seawater circuits: The AWI has several distributed aquarium facilities in the Bremerhaven urban area. These will now be bundled together with a new building. The building, which will cover a good 1000 square meters, will contain three self-contained circulation systems, each with about 20 cubic meters of seawater. These reflect the Polar Sea, North Atlantic and North Sea habitats to be studied. Each circulation system can be individually tempered between -2 °C and +20 °C. Commissioning is planned for…

More than 280 scientists from all over the world are meeting in Bremerhaven for the "International Symposium on Sea Ice". Their common goal is to exchange research methods and results on the topic of sea ice and snow in the Arctic and Antarctic. The conference will run until June 9. More info.

In response to climate change, the mean sea surface temperature has risen substantially. Yet some ocean regions like the Southern Ocean encircling Antarctica have hardly warmed at all, or even grown slightly cooler, over the past 40 years. A team of experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) has now succeeded in confirming that this phenomenon is only a temporary state at the beginning of an extremely long-term climate change, in the course of which precisely those areas that are cooler today will warm…

The Alfred Wegener Institute, Helmholtz Centre for Marine and Polar Research (AWI), is delighted to announce the start of the last cohort of the NF-POGO Centre of Excellence at AWI, a comprehensive oceanographic training programme on the North Sea Islands of Helgoland and Sylt. The new participants from the Philippines, Sri Lanka, India, Madagascar, Tanzania, Somalia, Lebanon, Portugal, Brazil and Argentina will be the last cohort before the ten-year programme rotates to another hosting institution.

AWI Director Antje Boetius presented the international Antarctic program "Antarctica InSync" at this year's ATCM meeting in Helsinki: The project will study Antarctica year-round with international partners. The ATCM is the annual consultative meeting of the Antarctic Treaty States. At the conference, decisions are made by the treaty states for Antarctica, since this continent itself has no government.

Microbial communities in marine sediments are able to use ancient material as a carbon source. Although they prefer fresh organic material, if there is not enough of it, microbes also use carbon from rocks. Since this bacterial metabolism releases greenhouse gases, this process is an additional source of fossil greenhouse gases. This is the result of a study led by the Alfred Wegener Institute, which has now been published in the journal Nature Geosciences. 

There are many effects of climate change. Perhaps the most broadly known is global warming, which is caused by heat building up in various parts of the Earth system, such as the atmosphere, the ocean, the cryosphere and the land. 89 percent of this excess heat is stored in the oceans, with the rest in ice and glaciers, the atmosphere and land masses (including inland water bodies). An international research team led by the Helmholtz Centre for Environmental Research (UFZ) and with participation of scientists from the Alfred Wegener Institute has now…

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.

Today, Monday, 22 May 2023, the Research Vessel Polarstern will leave her homeport in Bremerhaven, catching the afternoon high tide at ca 3:00 pm and bound for the Arctic Ocean. The four-week expedition, slated to end on 19 July in Tromsø, Norway, will focus on extended ecological fieldwork at the AWI’s deep-sea observatory Hausgarten and at the FRAM Ocean Observing System between Greenland and Svalbard. 50 researchers and a ship’s crew of 24 will be on board.

Manganese nodules in the deep sea contain a wealth of valuable metals that are vital to e.g. the electronics and steelmaking industries. Accordingly, these sectors and many countries have pinned their hopes on deep-sea mining to meet the growing demand for raw materials like cobalt and rare-earth elements. In a study just released in the journal Scientific Reports, experts from the AWI show that such activities could not only have ecological impacts, but also pose health hazards, e.g. in connection with the industrial mining and processing of the…
