Title: NOAA Point Shapefile - 100m2 Fish Density for Virgin Passage, United States Virgin Islands, Project NF-10-03-USVI, 2010, WGS84
Short Name: VP_2010
Status: Completed
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 Virgin Passage, 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.

Lineage

Process Steps

Process Step 1

CC ID: 461228
Description:

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

Process Date/Time: 2010-01-01 00:00:00

Process Step 2

CC ID: 461229
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/Time: 2010-01-01 00:00:00

Process Step 3

CC ID: 461230
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/Time: 2010-01-01 00:00:00

Process Step 4

CC ID: 461231
Description:

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