Water and sediment chemistry, and elemental (C/N ratios) and isotopic (delta 13C, delta 15N) data collected aboard R/V Endeavor cruise EN510 in the Gulf of Mexico from 2012-06-27 to 2012-07-04 (NCEI Accession 0205623)

This dataset contains water and sediment chemistry, and elemental (total C and N, C/N ratio) and isotopic (delta 13C, delta 15N) data collected during R/V Endeavor cruise EN510 in the northern Gulf of Mexico from 2012-06-27 to 2012-07-04. The water column and sediment chemistry data includes water column salinity, pH, concentration of dissolved nutrients, dissolved gases, total particulate nitrogen (TPN), total particulate carbon (TPN), particulate organic carbon (POC), and particulate inorganic carbon data acquired from CTD casts and multiple corer drops. The elemental and isotopic data includes the delta 13C and 15N, total Nitrogen and Carbon, and the C/N ratio. The particle samples were collected using a CTD-rosette and a MOCNESS. The objectives were to characterize the physical and chemical properties in the water column at/near cold seeps in the northern Gulf of Mexico. All the data records also include sampling information (time, date, location, collection type, and depth).
