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).
