Exzellenzcluster 80 (EXC): Ozean der Zukunft

Description: Das Projekt "Exzellenzcluster 80 (EXC): Ozean der Zukunft" wird vom Umweltbundesamt gefördert und von Helmholtz-Zentrum für Ozeanforschung Kiel (GEOMAR), Forschungsbereich 2: Marine Biogeochemie, Forschungseinheit Marine Geosysteme durchgeführt. The aim of this project is to test the hypothesis that nitrogen fixation is stimulated in organic-rich surface sediments of marine oxygen minimum zones (OMZ s) and represents an important link between nitrogen and sulfur cycling via N2-fixing sulfate-reducing bacteria. A multidisciplinary set of methods (microbial rate measurements, nifH-gene analyzes, 15N-labelling, HISH-SIMS, CARD-FISH, porewater geochemistry) will be applied to sediments from different OMZ s (off Peru, off Mauretania, Koljø Fjord).
