| Description | Dr. Jahnke first determined the correlation between seafloor oxygen flux (of which there are relatively few measurements) and extensive data on sedimentary organic carbon, CaCO3, and accumulation rate. He then used this empirical correlation to interpolate and extrapolate the benthic oxygen flux measurements to 61N to 61S in the Atlantic, Pacific and Indian Ocean basins. The data are limited to depths > 1000 m. Since benthic oxygen flux is driven by remineralization of particulate organic matter, it is a close approximation of the flux of particulate organic carbon from the overlying water column. |
