Gelatinous zooplankton from the Fram Strait region, Arctic Ocean (Photo: Mario Hoppmann/AWI) Gelatinous zooplankton, comprising cnidarians, ctenophores and tunicates, are known to be major drivers of ecosystem [...] Using eDNA, we want to monitor “newcomers” and community changes in rapidly changing regions such as Fram Strait, the gateway to the Arctic, and the Atlantic-influenced Kongsfjorden (Svalbard). Eventually [...] get an accurate estimate of jellyfish diversity, distribution patterns and abundances. During the FramJelly project, a collaboration between AWI and GEOMAR, on PS126 (schematic below), we compared the

Wegener Institute established the LTER (Long-Term Ecological Research) observatory HAUSGARTEN in the Fram Strait. HAUSGARTEN observatory displays 21 permanent stations covering a water depth range of 250 [...] HAUSGARTEN observatory is successively extended within the frame of the HGF infrastructure project FRAM (Frontiers in Arctic marine Monitoring).
