Science objectives

This cruise objectives are to:
1) characterize the local geology of brine seeps using ALVIN multibeam and ATLANTIS multibeam surveys;
2) collect sediment and brine samples from brine seeps using ALVIN;
3) collect water samples from above brine seeps using the CTD rossette;
4) collect sediment samples from around brine seeps using the multiple corer;
5) collect zooplankton samples using the MOCNESS;
6) collect water from brine basins using the  CTD rossette and "brine depth profiler" operated from ALVIN;
7) conduct sediment and water column sampling at three sites in the vicinity of the Macondo wellhead.

Science Activities

This cruise will collect fluids from the water column (using the CTD rosette) and from brine basins and seafloor brine pools using the CTD rossette and a cumstimized brine fluid sampler (for profiling over depth in stratified brines). We will also collect sediment push cores using ALVIN and a multiple corer (during night ops). We plan to visit between 10 and 12 different brine-impacted cold seeps along the Northern Gulf shelf and slope. We will also spend three days working around the Macondo Wellhead. We will also conduct multi-beam mapping from ALVIN and from the ship (during night ops).

Pre-cruise planning meeting: Teleconference

Media personnel on board: Video, Writer
Antonia Juhasz is an investigative journalist and popular science writer. She will be doing EPO blogs and writing several stories related to the cruise. National Geographic will have crew (out on a sister ship) filming our activities around the Macondo wellhead. Bill Evelyn, a UGA employee in Broadcast Video/Science journalism will be on board for part of the cruise capturing video for a documentary film that UGA will produce. We will also have a media event in port before the cruise sails.
