OCEANS - Bergen, 2013 MTS/IEEE. doi:10.1109/OCEANS Bergen.2013.6608008 Publications featuring [...] FRontiers in Arctic marine Monitoring Our ability to understand the complex interactions of biological, chemical, physical, and geological processes in the ocean and on land is still limited by the lack [...] interdisciplinary observation infrastructures. The main purpose of the planned open-ocean infrastructure FRAM (FRontiers in Arctic marine Monitoring) is permanent presence at sea, from surface to depth, for the

Radiation stations determine the fraction of incident light which is reflected by the surface or [...] novelty in under-ice robotics. BioOptical Platform Sinking particles control CO2 transport to the deep ocean. AWI and MARUM researchers developed the BioOptical Platform BOP, which combines a camera system and

We know little about the fish stocks in the central Arctic Ocean, and what we know about the local ecosystem is insufficient to ensure sustainable management. In response, in June 2021 the Agreement to [...] to Prevent Unregulated High Seas Fisheries in the Central Arctic Ocean – which includes a moratorium on fishing in the region – entered into force. The European Union and nine other countries signed the

Since the marginal ice zone of the Arctic Ocean is a highly dynamic environment, it is crucial to track the position of the ice edge in order to define AUV (Autonomous Underwater Vehicle) mission parameters
