Abstract:
A better understanding of the oceans' carbon cycle and a reduction in existing uncertainties in estimates of CO 2 fluxes between the atmosphere and the oceans have become central to several contemporary programs. Oceanic CO 2 fluxes are largely regulated by the “solubility pump” and the "biological pump." The solubility pump is governed by physical processes that include near‐surface conditions at the air‐sea interface, the partial pressure of CO 2 between the sea surface and the atmosphere, and the solubility of CO 2 in seawater. The biological pump, in turn, is regulated by phytoplankton photosynthesis, which converts CO 2 to organic matter. The fraction of newly photosynthesized carbon exported to depth in the oceans is referred to as “export production” or “new production,” and is largely dependent on exogenous nitrogeneous nutrient inputs, primarily nitrate into the euphotic zone [ Eppley and Peterson , 1979].
