Dataset Overview | National Centers for Environmental Information (NCEI)

CTD, and water and sediment chemistry data collected aboard R/V Endeavor cruise EN528 in the northern Gulf of Mexico from 2013-07-07 to 2013-07-23 (NCEI Accession 0217734)

Preview graphic

This dataset contains CTD, and water and sediment chemistry data collected aboard R/V Endeavor cruise EN528 in the northern Gulf of Mexico from 2013-07-07 to 2013-07-03. The CTD data were collected using a CTD-rosette system and includes binned profiles and bottle files along with the header files. The physical and chemical properties in the water column at the ECOGIG seep and other study sites were characterized. 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 (TPC), particulate organic carbon (POC), and particulate inorganic carbon data acquired from 40 CTD casts and 11 multiple corer drops.
