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 Biogeochemische Modellierung durchgeführt. By employing a new computational framework to efficiently simulate the transport of biogeochemical tracers in ocean circulation models, we propose to extend the applicability of the Kiel Climate Model (KCM) to time scales of several thousand years. This is orders of magnitude longer than the few-hundred year simulations currently possible, and it will enable us apply the state-of-the-art KCM, so far used to simulate the present and future ocean, also to paleo scenarios. To prepare the ground for future paleoceanographic applications, the work proposed here has two aims: 1. implement and test the computational method for the KCM, 2. use the new method to develop and identify a description of the sedimentation and remineralisation of particulate organic matter (POM) that, for our best estimate of the present ocean circulation, generates nutrient and oxygen distributions consistent with observations. By implication, this should be most appropriate for multimillennial simulations, including those required by paleo studies.
