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. We propose to develop a computationally efficient way of coupling benthic and pelagic components of biogeochemical ocean and climate models. Neural network-based techniques are to be employed in order to provide the biogeochemical ocean model component with benthic boundary conditions that are consistent with its spatially and temporally varying simulated watercolumn properties. In this novel approach, the neural network associates actual bottom-water properties and sedimentation fluxes simulated by the water column model with consistent local steady-state fluxes of biogeochemical tracers across the sediment surface. This concept does not require long spin-up simulations of the coupled benthic-pelagic models over tens of thousands of years, and instead relies on previous training of the neural net s associative mapping capacity by a large number of long, computationally inexpensive, runs of a one-dimensional benthic model under varying bottom-water and sedimentation-flux conditions.
