Description:

Abstract:

        This data contains densities of fishes detected using mobile fisheries sonar on board the NOAA Ship Nancy Foster.  The data were acquired in concert with a multibeam bathymetry survey of St. John Shelf, off the coast of United States Virgin Islands in 2010.  Fish densities are presented by size classes, corresponding to individual lengths inferred from the intensity of acoustic target return, in units of fish per 100 square meters.

Purpose:

        To design and implement a mobile fisheries sonar survey in concert with multibeam echosounder hydrographic surveys to assess and map fish densities and biomass within management priority areas.2. To assess distribution of fish densities relative to management areas and habitat types. 3. To assess location and size of purported reef fish spawning aggregations.

Completeness_Report:

These data consist of fish densities in St. Johns Shelf, United States Virgin Islands. The data was collected during corresponding multibeam operations.

Lineage:

Process_Step:

Process_Description:

Acoustic data was collected aboard the NOAA Ship Nancy Foster using ES120-7C splitbeam transducer. The Kongsberg ES120-7C and ES38-B transducer was deployed via a hull mounting bracket aboard the R/V Nancy Foster. Kongsberg ES transceivers and Simard ES60 software was used in the data acquisition. Data was collected during all shifts of multibeam survey.

Process_Date: 2010

Process_Step:

Process_Description:

Echoview 4 was used in this step of the data processing. The EK60 .raw file format was edited for erroneous ping returns and acoustic noise. Fish were track using a tracking algorithm and the fish tracks were export in a .csv format.

Process_Date: 2010

Process_Step:

Process_Description:

A R script was used to calculate the density and size of fish through out the water column. Then projected in 100 square meter resolution ArcGIS shapefile.

Process_Date: 2010

Process_Step:

Process_Description:

Arc Catalog was used to merge the daily shapefiles into one cruise shapefile.
