Biogeochemical OGCM HAMOCC including particle dynamics

The HAMOCC5 model in its basic version includes the three reservoirs atmosphere, water column, and bioturbated sediment. The full carbon, nitrogen and silicon cycles are simulated. The sediment part includes the dissolved and solid components for organic carbon (dissolved form TCO2), silicon, inorganic carbon (CaCO3) and clay. The particle aggregation mechanism according Kriest and Evans (1999, 2000) was implemented. As water column processes and sediment accumulation occur on different time scales, an acceleration method was developed which allows the build-up of the model sediment within the normal spin-up times of the model (within a few months turnaround time on the computer corresponding to 1000-1500 model years).
