Following an invitation of Laurence Mee, Director of The Scottish Association for Marine Science (SAMS) - a partner institute of HYPOX, Jana Friedrich (AWI) and Felix Janssen (MPI) are spending a week at SAMS, Oban (UK). The purpose of the visit is the test of a new benthic chamber system, which will be used in field studies during the HYPOX project. The benthic chamber system has been developed during a Royal Society International Joint Projects grant in a collaboration of AWI, MPI, University of Plymouth and SAMS. The deployment of the system will be carried out from RV “Calanus”, the SAMS ship, at the proposed hypox project sites in Loch Etive. The chamber design is optimized to penetrate hard, consolidated sediments at minimum perturbation of the sediment surface. Total benthic oxygen uptake data will be derived from recordings of an oxygen macro optode in the chamber. In addition, nutrient fluxes will be calculated from time series of chamber water samples. Once operational, the chamber will mainly be used for investigations of benthic fluxes at the Romanian Shelf (northwestern Black Sea).
