CHROMOPHORIC DISSOLVED ORGANIC MATTER IN THE CHESAPEAKE BAY
 
Dissolved organic matter (DOM) has been shown to behave more or less conservatively in some estuarine systems, while in others distinct non-conservative behavior has been demonstrated. In order to examine the fate and transport of terrestrial DOM in coastal regions, dissolved organic carbon (DOC), DOM fluorescence and DOM absorbance were measured from 0 to 30 parts per thousand salinity in the Chesapeake Bay. In addition to discrete samples taken from an in-line pumping system, continuous flow-through measurements of absorbance at 337 nm and stopped flow fluorescence excitation-emission matrices every mile or so were taken. These high resolution surface measurements are compared with CTD rosette sampling as well as DOM fluorescence measurements made on a towed undulating vehicle. The results from the Chesapeake Bay will be compared with similar high resolution measurments performed in Boston Harbor.
