Abstract:

Hydrographic data were collected during cruise EN527 using a CTD-rosette system aboard the R/V Endeavor. We characterized the physical and chemical properties in the water column at ECOGIG seep and other study sites. The ship departed Gulfport MS on 06/19/2013 and collected samples at ECOGIG sites before returning to Gulfport on 07/03/2013. Binned profiles and bottle files are available through this link, and raw CTD data are available on request.
