Colored and Chromophoric Dissolved Organic Matter in Natural Waters
Ocean color remote sensing could be applied to estimate DOC transport in
river-ocean transects, depending on the robust empirical relationships between
DOC and CDOM, CDOM and salinity, and salinity and river flow (del Castillo
and Miller 2008). A flow chart is depicting the method and rationale for the estimate of DOC transport (Fig. 11). The success of this approach depends on four
conditions (del Castillo and Miller 2008): (1) DOC and CDOM must behave conservatively at the study site; (2) The relationship between CDOM and DOC in the
river end member must remain constant; (3) One should be able to derive CDOM
from satellite ocean color measurements; (4) Salinity in the study area should
