What does this data set describe?

Title:
NOAA Point Shapefile - 100m2 Fish Density for Flower Gardens National Marine Sanctuary, United States, R/V Manta, 2010, WGS84
Abstract:
The design of this field mission is three fold: (1) to spatially characterize the distribution, abundance and size of both reef fishes and macro invertebrates within and around the waters of the Flower Gardens National Marine Sanctuary using, (2) to relate this information to in-situ data collected on associated habitat parameters and (3) to use hydroacoustics technologies for a comprehensive assessment of East and West Bank. This information collected will be used to evaluate the utility of an experimental fishing closure on one of the most pristine reefs under US jurisdiction in the tropical Western Atlantic. Data collected during this mission (pre-closure) will provide baseline information necessary to evaluate closure efficacy and assess whether the closure should become permanent.

Why was the data set created?

1. 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 and outside proposed management zones.2. To assess distribution of fish densities relative to management and ecological reserve boundaries and other differences that may be associated with management zones and habitat types, particularly as fish distributions relate to movements between habitat types.3. To assess the extent of fish density distributions in comparison with diver visual surveys and fish community assessments.


How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    Date: 2010 (process 1 of 4)
    Acoustic data was collected aboard the NOAA R/V Manta using ES120-7C splitbeam transducer. The Kongsberg ES120-7C tansducer was deployed using a moon pool. Kongsberg ES transceiver and Simard ES60 software was used in the data acquisition. Data was collected during all shifts of multibeam survey.

    Date: 2010 (process 2 of 4)
    Echoview 4 was used in this step of the data processing. The .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.

    Date: 2010 (process 3 of 4)
    Microsoft Office Excel 2007 was used to calculate the density and size of fish throughout the water column. Divided fish into 100 meter square area and created a new workbook with the calculated fish sizes and densities.

    Date: 2010 (process 4 of 4)
    Arc Catalog was used to convert the .xlsx file format to shapefiles. Set the geographic coordinate system to WGS 84. Then merged the all the .shp file into one .shp file with all the trip data.
