Arrival: Dec 3, 2010

Gulfport MS

Operations Area

Gulf of Mexico
Lat/Lon: 27° 43.4′ N / 90° 16.8′ W
Depth Range: 650 / 2600
Will the vessel be operating within 200 NM of a foreign country? no
Are visas or special travel documents required? no

Science Objectives

The primary objectives of this cruise are to collect depth stratified samples of brine fluids from brine pools, brine basins, mud volcanoes, and the surrounding sediments at sites in the Northern Gulf of Mexico. Secondary objectives are to map the sites, collect water column profiles above the brine habitats (via night time CTD casts), and make air-sea flux measurements of methane and carbon dioxide. 
Please note that I have requested 3 additional dives/days from the NSF to collect sediment and water columns samples in the vicinity (2.5 miles and further out) of the Deepwater Horizon wellhead.  Our objectives at these sites would be to collect water column (CTD) and sediment (ALVIN) samples at three sites and to map the seafloor around the area. 

Science Activities

Science activities include 1) Alvin dives, 2) CTD casts, 3) mapping surveys, and 4) air-sea gas exchange measurements.  
During Alvin dives, we will collect brine samples with a custom built sampling device; collect sediment push cores; photo and video the study sites; and deploy monitoring sensors and camera systems.  
Night operations will include multibeam surveys and CTD casts.  
Gas exchange measurements will be made continuously with an underway system.
