FS FRIEDRICH HEINCKE

Dr. Alshuth participated in several oceanographic and ichthyological research expeditions on research vessels of the Marine Biological Research Station Helgoland in the German North Sea onboard the RV UTHÖRN - as Chief Scientist and on RV FRIEDRICH HEINCKE in 1987. Her oceanographic research associated with: Reproduction and Recruitment of the sprat, Sprattus sprattus, in the North Sea Project. Funded by the DFG (Deutsche Forschungs Gemeinschaft) as part of the IREP (International Recruitment Project), as part of the Ocean Science and Living Resources Program of IOC (Intergovernmental Oceanographic Commission) and FAO. Research focused on various trends of global change (i.e. accumulation of atmospheric greenhouse gases and other anthropogenic effects such as pollution, harmful algae blooms, overfishing, coastal development) may have major effects on marine ecosystems and the living resources that they contain. Publication related to these expeditions include:
