29. Our in situ measurements of spectral downwelling irradiance in the APFZ indicated that the 0.1% level of surface irradiance at 490 nm is, on average, 94 m. To a first approximation, we assume the 100 m depth delimits the upper layer where most organic carbon production by photosynthesis occurs. From vertical profiles of POC concentration, we established the relation between the water column POC integrated from the surface to 100 m depth (in milligrams per square meter) and the surface concentration of POC (in milligrams per cubic meter), which is: POC (water column-integrated) = 53.36 (±3.83) · POC (surface concentration) + 2341.41 (±361.56). The standard errors of the regression coefficients are given in parentheses, the squared correlation coefficient is 0.894, and the number of observations is 25.

The apparent optical properties (AOPs) are those properties that depend both on the medium (the IOPs) and on the geometric structure of the ambient light field, and that display enough regular features and stability to be useful descriptors of the medium [R. W. Preisendorfer, Union Geod. Geophys. Inst. Monogr. 10, 11 (1961); (3)].
