Area of Operations: Madison Swanson Marine Reserve, Steamboat Lumps Marine Reserve, West Florida Shelf, Florida, United States, Gulf of Mexico, North America, North Atlantic

Dates: November 20, 2003 to November 24, 2003

Objectives: To complete collection of sea floor video data begun on REEFS1 cruise FA 03036 in September 2003. Video data were collected using Sony mini-DV camera on a towed camera sled. These data will be used in conjunction with existing sidescan sonar, multibeam, sedimentologic, and biologic data to create habitat maps.

Type of Activity: videography

Information to be derived: Habitat maps

Summary: This cruise was a continuation of FA 03036 which was aborted because of bad weather and ship engine problems. Although we had the FSU ROV onboard we did not use it. All data on this leg were collected using the towed camera sled Rose Bud carrying a Sony mini-DV camera with lasers spaced 20 cm apart and the Helios underwater video lighting system. As on Leg 1, the sled was towed at about 1 kt for 45 minutes. Sites were numbered consecutively with Leg 1, beginning with Site 14 and ending on Site 28. Sites 14-25 were in Steamboat Lumps Reserve; Sites 26-28 were in Madison Swanson Reserve. Data quality was very good to excellent except at Site 15 which was very poorly focused.
