Abstract:

Hydrographic and water column data were collected during R/V Endeavor cruise EN528 from 2013-07-08 to 2013-07-23 using a CTD-rosette system. We characterized the physical and chemical properties in the water column at the ECOGIG seep and other study sites. The ship departed Gulfport, Mississippi, on 2013-07-07 and collected samples at ECOGIG sites before returning to Gulfport on 2013-07-24. Binned profiles and bottle files are available through this link, and raw CTD data are available on request.
