constant distance from the surface (e.g. underside of sea ice) or bottom. AWI has developed a “depressor” that allows operation in medium-severity sea ice conditions. It can also be deflected horizontally [...] with light to moderate sea ice cover. It was used for the first time during the Polarstern PS131 expedition and allowed the collection of valuable data in the marginal ice zone north of Svalbard. Further

Moreover, the tremendous amounts of meltwater produced could influence ocean currents, sparking massive changes in the climate, especially in the North Atlantic [...] accurately simulates the past, it can also project the future, paving the way for forecasts on e.g. future sea-level rise or global warming. In this way, these models provide the scientific basis for formulating [...] floodwalls and levees are costly. That’s why it’s important to be able to estimate today how much the sea level will rise, or how much the intensity of hurricanes will increase, tomorrow. Climate modeling

Less sea ice means e.g. that winds produce larger waves [...] in the Arctic is insulated by water and sea ice, one might assume there was no permafrost there. But guess again: at the bottom of certain shallow coastal seas, the ground is permanently frozen. This type [...] there was so much water frozen in the massive inland ice sheets of Scandinavia and North America that in some places, the sea level was 120 metres lower than today. Where now we see ocean waves, there was
