| EK60 Water Column Sonar Data Collected During NF-12-01-USVI |
| NF-12-01-USVI Characterization of Seafloor Habitats of the U.S. Caribbean (EK60).
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 moderate-depth 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. |
