Abstract:

Hydrographic data were collected during cruise AT2613 using a CTD-rosette system aboard the R/V Atlantis. We characterized the physical and chemical properties in the water column at brine pools and the ECOGIG seep study sites. The ship departed Gulfport, MS, on 2014-03-29 and collected samples at a variety of brine pools and ECOGIG sites before returning to Gulfport on 2014-04-22. Samples were collected 2014-03-31 - 2014-04-20.
