HAUSGARTEN oxygen workshop at AWI (10.-11.3.2010)

Thomas Soltwedel from the german Alfred Wegener Institute for Polar and Marine Research (AWI) organizes a workshop on oxygen measurements at the deep-sea long-term observatory HAUSGARTEN, which serves as an open ocean reference site within HYPOX. The prime intention of the workshop is to compile and secure all oxygen records assessed during the last 10 years of intense multidisciplinary studies at HAUSGARTEN observatory by a variety of methods: on board Winkler titrations of bottom water and in-situ incubation chamber samples, in-situ and on board microprofiler measurements as well as short- and long-term measurements with 1D Aanderaa optodes and 2D planar optodes. The compiled data will be transferred to the PANGAEA repository and thus be available via the HYPOX data portal. Workshop participants plan to use the data to assess fluxes and remineralization of organic matter and its influence on sediment oxygenation as well as for the analysis of long term trends in bottom water oxygen concentration.

All in all eight scientists from three institutions join the workshop at AWI: Cécile Cathalot & Christophe Rabouille (CEA-CNRS), Eberhard Sauter, Frank Wenzhöfer, Ingo Schewe & Thomas Soltwedel (AWI), and Janine Felden (MPI-MM). Colleagues from UGOT are not attending the workshop but provide their oxygen data collected at HAUSGARTEN in summer 2007.
