Summary Information for Field Activity 2004-021-FA

Area of Operations: Atwater Valley, Mississippi Canyon, Gulf of Mexico, North America, North Atlantic

Dates: June 20, 2004 to June 23, 2004

Chief scientist: Deborah Hutchinson

Rob Evans - WHOI

Objectives: Collect bottom camera and electrical resistivity data across two possible gas hydrate mounds in the Mississippi Canyon, northern Gulf of Mexico, as part of a site survey for the JIP/DOE Gas Hydrates Drilling Program.

Type of Activity: Bottom photography; Bottom resistivity profiling (WHOI);Bottom Photography
Bottom resistivity profiling (WHOI)

Information to be derived: bottom imagery to investigate benthic distribution and gas hydrate
electrical resistivity profiles across mounds and at drilling transects

Summary: This was a successful cruise with 5973 bottom images collected on four tows; the EM data fulfilled the objective of showing proof of concept for the system (17 km on 9 lines).
