Abstract:

Colored dissolved organic matter CDOM absorption and salinity relationships were assessed and used in conjunction with the salinity and current outputs of a numerical model Navy Coastal Ocean Model NCOM to study CDOM dynamics in the northern Gulf of Mexico. In situ CDOM absorption and salinity obtained from multiple field campaigns were inversely correlated seasonally winter spring and summer and latitudinally inner- and outer-shelf zones, suggesting conservative behavior of CDOM distribution. A weaker correlation, during summer in the outer-shelf zone, however, indicated stronger effects of photooxidation and lower masking effects from riverine CDOM. Applying these relationships to simulated salinity resulted in hourly maps of CDOM that revealed similarities to CDOM patterns derived from SeaWiFS satellite imagery.
