Area of Operations: Pulley Ridge, west Florida platform, Florida, southeastern Gulf of Mexico, United States, North America, North Atlantic
Dates: April 24, 2003 to May 01, 2003
Chief scientist: Dave Twichell
Robert Halley, USGS, St. Pete; Al Hine - USF
Objectives: Map and image deep water reef communities in the Pulley Ridge area of the eastern Gulf of Mexico. Multibeam mapping and Chirp high-resolution seismic profiling will be conducted using USF equipment. The USGS SEABOSS system will be used to obtain high-resolution images of these reef communities.
Type of Activity: Sampling; Seismic profiling; Photography;
Information to be derived: Time series data; Samples and chemical analysis; Habitat maps; Sea floor map; Bathymetric maps;
Summary: Video transects: 14 (18 hrs tape); Still photos: 1161; Seismic lines: 9; Multibeam regions: 3; Coral (Leptoceris cuculata) samples: 18; SEABOSS grabs: 9; Dredge sample: 1. Coral samples and grabs in St. Petersburg with Kate Ciembronowicz. Video and still photos in St. Petersburg with Kate Ciembronowicz and in Woods Hole with Dann Blackwood. Seismic, multibeam data and dredge data at USF with Brett Jarret. Digital logs in St. Petersburg with Kate Ciembronowicz.
