dc.description.abstractThe Monsoonal impact on the deep ocean fluxes, organic carbon export into the ocean's interior, and the difference between the deep-sea organic carbon fluxes and sedimentary organic carbon burial rates in the Arabian Sea were assessed. The variations of the depth of the mixed layer and the euphotic zone control the organic carbon export in the Arabian Sea except in regions influenced by upwelling during the SW Monsoon. The strength of the upwelling and the height of the subsequent export of organic matter are mainly determined by the intensity of the Findlater Jet. Moreover, the strength of the physical forcing mechanism, also influences the plankton composition whereby stronger forcing favours diatom blooms and lowers the carbonate/ biogenic opal ratios. Such changes are assumed to have lowered the atmospheric CO sub(2) concentration significantly during glacial times. The differences between estimated deep ocean fluxes derived from satellite data and measured deep fluxes are lower than by a factor two in Arabian Sea. The organic carbon burial rates in Arabian Sea related to primary production and carbonate accumulation reveal an acceptable agreement on a global scale except at sea floor spreading zones and continental margins.
