The main goal of our arctic research [...] a 100 m water column, is stated for analysis between 1991 and 2013, during summer months. While in FRAM strait and on the arctic shelves, a relatively high proportion of biomass was being observed, the

The long-term analysis of blue whale and fin whale vocalisations in the eastern Fram Strait offers valuable insights into seasonal and annual patterns regarding these species’ occurrence in the region

deep-sea focus has been on the Arctic. In 1999, the institute established a long-term observatory in Fram Strait between Greenland and Svalbard. Today, the HAUSGARTEN observatory consists of 21 monitoring [...] temperatures are provoking rapid responses in the deep-sea ecosystem. This can already be seen in Fram Strait between Svalbard and Greenland, where the composition of the phytoplankton has changed. Whereas [...] As such, it’s quite possible that climate change will reduce diversity in the biotic communities of Fram Strait. To FAQ element How will it affect the Arctic deep sea when the sea ice continues to melt?
