site were also impacted: outdoor tanks and samples froze, water lines iced over, and suction pipes and pumps were damaged by swell and ice. As a result, some samples had to be collected multiple times, and [...] struggled when the harbor was packed with solid ice, and at times, dive trips had to be aborted because the boats could not break through the thick ice to leave Ny-Ålesund harbor. Despite the many setbacks [...] survival training—including a night on the sea ice—we embarked on our mission at Arrival Heights near McMurdo Station. Cutting through 1.7 meters of sea ice revealed a fascinating underwater ecosystem dominated

Depending on the exact parameters chosen, this results [...] 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 to [...] regions 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
