Cross-slope variations of dissolved organic carbon in the Gulf of Cadiz, NE Atlantic Ocean (February 1998)
International audience Our observations at a traverse of Cadiz in February 1998 indicated dissolved organic carbon (DOC)con- centrations ranging from 61 to 89 uM C within the Spanish Shelf Water, from 48 to 64 uM C within the North Atlantic Surface Water, and from 49 to 55 uM C within the North Atla...
