Molecular Sea Ice Ecology Polar oceans are seasonally covered by sea ice with an average size of the continent of North America. Despite harsh conditions therein, sea ice and its lower surface can carry [...] community, typically dominated by Diatoms. Sea ice can provide important primary production to polar oceans via these communities, although they are often very patchy. In times of declining sea ice coverage [...] biodiversity, functions provided by its biota, and the future of sea ice communities in a warming ocean. We address these questions through analyses of total communities, their molecular biodiversity and

becoming more frequent and intense. The Arctic Ocean also suffers from this development: The absence of sea ice will lead to more extreme fluctuations in ocean temperatures, with abrupt temperature changes [...] Wegener Institute shows how marine heatwaves will also become much more intense and frequent in the Arctic in the 21st century. With drastic consequences for the ecosystem. The researchers published their

For top athletes, the lactate level is a way of measuring their fitness. In contrast, for Arctic fish that are subjected to rising temperatures, the lactate is an indicator that they are consuming [...] spectrometer with cryoprobe.

Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) are setting out with the research vessel Polarstern towards [...] research group. In this way researchers can analyse the climatic changes in the Arctic and their impact on the fauna in the future with higher temporal and spatial resolution.

Climate Research
The Arctic Ocean in summer will very likely be ice free before 2050, at least temporally. The efficacy of climate-protection measures will determine how often and for how long. These
