Determining net dissolved organic carbon production in the hydrographically complex western Arctic Ocean

Each spring and summer, the Chukchi Sea in the western Arctic Ocean experiences a short but intense phytoplankton bloom that is controlled by sea ice cover, nutrient availability, and river runoff. During the bloom, dissolved inorganic carbon (DIC) concentrations are drawn down in the mixed layer (shelf, similar to Delta 100 mu mol kg(-1); shelf-break, similar to Delta 50 mu mol kg(-1); basin,
