Field Activity 2001-010-FA

Identifier 2001-010-FA
Alternate names IB S-1-01-GM
Purpose Use sidescan sonar, multibeam bathymetry, and high-resolution seismic data to map the geologic framework and distribution of deep water reefs west of the Florida Keys. An ROV was used to video the deep-water reef to determine extent and composition of benthic biota.
Location Pulley Ridge, southeastern Gulf of Mexico, Florida, United States, North America, North Atlantic;
Summary Cruise ended early due to World Trade Center terrorism and tropical depression forming in the study area.
Comments Original Center People field contained: Chuck Worley - technician to maintain sidescan and navigation gear; Erika Hammar-Klose - processor for sidescan mapping; Ken Parolski - cruise mobilization. Project = Deep-water reefs, Deep-water reefs
