EK60 Water Column Sonar Data Collected During NF-10-03-USVI |
NF -10-03-USVI Characterization of Seafloor Habitats of the U.S. Caribbean (EK60).
The Center for Coastal Monitoring and Assessment (CCMA) will be conducting the eighth
year of an ongoing scientific research mission onboard NOAA Ship Nancy Foster funded
by NOAA?s Coral Reef Conservation Program. The purpose of the cruise will be to collect
swath bathymetry and acoustical backscatter, as well as fishery acoustics data in
high priority areas in the U.S. Caribbean. Scientists will collect high resolution
multibeam and acoustic fisheries data in midwater depths approximately 30 to 1000
meters so as to continue to characterize seafloor habitats within all U.S. States,
Territories, and Commonwealths. The objective of this project is to collect a multibeam
bathymetry dataset with 100% seafloor ensonification, along with multibeam backscatter
suitable for seafloor characterization. Fishery acoustics data will be collected to
characterize broad-scale fish abundance, biomass, and utilization patterns, as well
as to locate and document fish spawning aggregations. Multibeam data will be collected
to conform to IHO Order 1 (less than 100m) and Order 2 (>100m) accuracy standards.
The strategies developed for each survey area will take into account the minimum depths,
general bathymetry, and time allotment. The delineation and identification of seafloor
habitats will be assisted by the use of a moderatedepth Remotely Operated Vehicle
(ROV) and drop camera. The vehicle has video and frame camera capability to depths
of 300 meters and will be used to point sampling within areas mapped during this mission. |
