Ziel der Reise / Objectives of Cruise:

HE577: The cruise HE 577 serves two purposes: The focus is on training master students from the Universitat Hamburg to conduct marine research on a research vessel. This training cruise has been part of the curriculum in Geology at Universitat Hamburg as a practical exercise for students at the M.Sc. level (lecture number 63-345) since 2006. The goals of this master course are (1) to learn ship-based operations at sea, (2) to apply and to use techniques to collect surface sediment and suspended matter samples, (3) to obtain water samples for biogeochemical measurements, (4) to obtain profiles of water column structure and water properties by CTD profiling, and (5) to get a first insight to acoustic techniques for the investigation of sediment layering and structure. During each evening of the cruise, students give seminars on topics related to geology and environment in the North Sea or on measurement and sampling techniques. The course also introduces to the software OceanDataView for data evaluation and visualisation. In addition to the purpose of student training, a second objective was to obtain samples of surface sediment for granulometric measurements and biogeochemical properties. This included the analyses of organic carbon, nitrogen, and for mapping the distribution of stable isotope ratios of nitrogen (15N/14N) in water-column particulate matter and surface sediments in the Danish and Norwegian Exclusive Economic Zone, respectively. This work is performed under research project "North Sea – Assessment of Habitats" (NOAH). The present set of samples will be analysed in the near future in the frame of B.Sc and M.Sc. theses.
