Ziel der Reise / Objectives of Cruise:
The groundfish survey aimed at estimating finfish biomass and distribution on the shelf area in the region between Tower Island and north of Joinville Island west of the Antarctic Peninsula (CCAMLR Subarea 48.1). We used a commercially sized hard bottom 'snapper trawl' commonly used in fisheries off Alaska: 61 hauls from 80 to 500 m, 3 hauls for biodiversity studies at 730 - 780 m depth; CTD measurements at selected stations; Genetic sampling and buoyancy measurements; identification and characterisation of the benthic invertebrate catch. Since the area is rarely visited by research vessels and bottom topography information are scarce, reconnaissance for suitable trawling grounds had to be performed. At the end of the cruise the field camps "Cape Shireff" on Livingston Island and "Copacabana" on King George Island were closed and stuff and staff taken on board.
