qAmong the changes in the
distribution of ocean carbon that could reduce glacial levels of atmospheric CO2 are:
q (1) fast downward organic carbon pumping in areas of costal
or tropical upwelling,
q (2) similar processes in Antarctic,
q (3) changes in the chemistry of Antarctic surface water
toward higher CO3-2 content,
q (4) changes in the chemistry of shallow subsurface water
originating from southern latitudes.
