collaborators have signed up to this project, and many have already set up fast-ice measuring sites at or near their Antarctic bases. Data collected under AFIN include ice and snow thicknesses, freeboard, dates [...] platelet layer from December onwards was associated with an inflow of warm surface water. We found that nearly half of the combined solid sea-ice and ice-platelet volume in this area is generated by heat transfer

Earth quite a bit warmer. However, this storage function has a high price: the oceans have become nearly 30 percent more acidic since the beginning of the Industrial Revolution. Sparkling water (Photo: [...] past 200 years. Since pH values are logarithmically compressed, this corresponds to a decline of nearly 30 percent. By 2100 the pH value of the oceans will presumably drop by another 0.3 to 0.4 units and

Continuous [...] of phytoplankton community structure, including the response to environmental forcing. In addition, near real-time data permits targeted sampling. Examples of targeted metatranscriptomics to assess community [...] Doppler Current Profiler and a CTD-probe, allowing continuous and automatic small-scale observations in near real-time of zooplankton species abundance and behavior (e.g. vertical migration and trophic interactions)

In [...] next research questions are, therefore: What do copepods eat if their favourite food, diatoms, has nearly vanished already when the animals wake up from their winter dormancy? Can they also live on significantly

The bright-green Dahurian Larch (Larix gmelinii) [...] them undetectable to satellite imaging – a fact that didn’t stop Katja Abramova (Lena Delta Reserve near Tiksi, Russia) from finding a smaller (only 30-cm-“tall”) larch in 2013, though it lost its crown
(December 2023 – January 2024), an expedition went to the AWI station “Kohnen”, which is sited at nearly 3000 m height on the plateau of East Antarctica. With 12 people, we worked several weeks at temperatures
2021, a field campaign took place in the Mackenzie Delta region of the Northwest Territories, Canada, near the communities of Inuvik and Tuktoyaktuk. Our goal is to study the current state of permafrost as
