DELIVERY OF DISSOLVED ORGANIC CARBON TO THE MID_ATLANTIC BIGHT FROM THE CHESAPEAKE AND DELAWARE ESTUARIES
 
The Chesapeake and Delaware estuaries deliver approximately 50 and 20 percent of the total freshwater inputs to the Mid-Atlantic Bight (MAB) respectively. These Freshwater inputs make a significant contribution to dissolved organic carbon (DOC) distributions on the shelf that may then be delivered to the open ocean. An instantaneous DOC flux was derived from high resolution DOC sampling and Acoustic Doppler Current Profiler (ADCP) measurements taken on a transect across the mouth of the Chesapeake on an August 1998 cruise. This flux will be compared with integrated fluxes determined from DOC/salinity relationships from our cruise and literature values in combination with freshwater flow measurements. Differences between the annual integrated flux and the instantaneous flux will demonstrate the complexity of riverine inputs to continental shelves. Near shore DOC inputs may be an important component in the global oceanic carbon budget.
