Ziel der Reise / Objectives of Cruise:
The work carried out during the RV 'Polarstern' expedition into the Arctic in summer 2011 contributed to the EU projects HERMIONE, HYPOX, ESONET and his successor EMSO, and to the PACES (Polar Regions and Coasts in the changing Earth System) research programme of the AWI which started in 2009. The research programme contributed to the time-series studies at the deep-sea long-term observatory HAUSGARTEN where we investigate the impacts of Climate Change on an Arctic marine deep-sea ecosystem through field studies, observations and models since 1999, which qualifies this station for ESONET, EMSO and the more recently ESFRI roadmap project SIOS (Svalbard Integrated Arctic Earth Observing System) coordinated by the Research Council of Norway. The work was based on the use of the unmanned Remotely Operated Vehicle (ROV) 'KIEL 6000; of the IFM-GEOMAR in Kiel. Among a standard sampling programme including exchange of moorings and free falling landers, the ROV was used for various in situ experiments. One dive took place at a location at around 400 m water depth west of Prins Karlsvorland where many methane seeps have been recorded recently with fishery echosounders. Further dives were carried out at the Vestnesa ridge and finally at the central experimental site of 'HAUSGARTEN'. Among these activities an Autonomous Underater Vehicle (AUV) was used for dives under the drifting sea ice and in open water. Water samples were collected, pCO2- concentrations, PAR, turbidity, chla a, temperature and salinity were measured en route.
