Ziel der Reise / Objectives of Cruise:

The expedition contributed to various large national and international research and infrastructure projects (FRAM, MUSE, iFOODis, HiAOOS, ICOS-D, SIOS) as well as to the new research programme "Changing Earth - Sustaining our Future" ("Erde im Wandel - Unsere Zukunft nachhaltig gestalten") of the Alfred Wegener Institute Helmholtz-Center for Polar and Marine Research (AWI). In Topic 6 "Marine and Polar Life: Sustaining Biodiversity, Biotic Interactions and Biogeochemical Functions" (Subtopics 6.1 "Future ecosystem functionality" and 6.3 "The future biological carbon pump") of the new research programme, ecosystem shifts in the pelagic and deep ocean associated with water temperature increase and sea ice retreat are identified and quantified, and feedback processes on oceanographic processes are investigated. These studies include the identification of spatial and temporal developments in the function of selected pelagic and benthic communities and the establishment of a comprehensive repository of observational data. In Subtopic 6.4 "Use and misuse of the ocean: Consequences for marine ecosystems", the input of plastic waste into the ocean, the vertic The work supports the time-series studies at the LTER (Long-Term Ecological Research) observatory HAUSGARTEN, where we document Global Change induced environmental variations on a polar deep-water ecosystem. This work is carried out in close co-operation between the HGF-MPG Joint Research Group on Deep-Sea Ecology and Technology and the PEBCAO Group ("Phytoplankton Ecology and Biogeochemistry in the Changing Arctic Ocean") at AWI and the working group Microbial Biogeochemistry at GEOMAR as well as national and international partners. The expedition was further used to accomplish installations for the HGF infrastructure project FRAM (Frontiers in Arctic marine Monitoring). The FRAM Ocean Observing System aims at permanent presence at sea, from surface to depth, for the provision of near real-time data on Earth system dynamics, climate variability
