Physical, nutrient, chlorophyll a and plankton abundance data collected from CTD and bottle casts aboard the R/Vs OCEANUS and ENDEAVOR in the Western Sargasso Sea and Northeast U.S. Shelf from 2004 to 2005 (NODC Accession 0053611)

Physical, chemical and biologic parameters were measured in the Western Sargasso Sea and Northeast U.S. shelf aboard the R/V Endeavor from 13 May to 31 May, 2004 and aboard the R/V Oceanus from 24 May to 11 June, 2005. Ocean properties surveyed include temperature, salinity, PAR, fluorescence from CTD; picoplankton abundance, chlorophyll-a and nutrients from bottle samples.
