Ziel der Reise / Objectives of Cruise:

This cruise is part of the 6th Framework Programme of the European Commission, the HERMES Integrated Project (Contract GOCE-CT-2005-511234 and see www.eu-hermes.net for further information) and is associated to Workpackage 2 "Coral Reef and Carbonate Mound Systems" led by Andre Freiwald. This cruise was dedicated to re-visit some of the northernmost coral reef complexes. Of particular interest were build-ups in the Tr?nadjupet, the R?st Reef and in the Stjernsund. The first two locations were discovered through dedicated seabed mapping surveys under the auspice of the IMR and Norwegian Geological Survey, whereas the Stjernsund site belongs to one of the famous Carl Dons locations. In addition, sites on the Sveinsgrunnen, Fugl?ybanken Trough and Sotbakken were searched for benthic communities as well. The objectives were: ? to map the reef architecture and geometry using a multibeam system. ? to measure physical watermass properties with CTD and water sampler. ? to document the sedimentary facies and biological habitats within and adjacent to reef complexes. ? to identify the species composition and their abundancies and functional role within the coral ecosystem. ? to analyse the postglacial geological evolution of coral reefs by obtaining long sediment cores. All these scientific results will be compared with existing information about cold-water coral ecosystems along the entire European and Mediterranean ocean margin.
