39215 Tech_Dive2012 Data Set Published / External 37133 FGBNMS Project Completed 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, (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. 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 ROV surveys and fish community assessments. 227 Theme ISO 19115 Topic Category environment Theme ISO 19115 Topic Category oceans Spatial Global Change Master Directory (GCMD) Location Keywords OCEAN > ATLANTIC OCEAN > NORTH ATLANTIC OCEAN > GULF OF AMERICA Theme CoRIS Discovery Thesaurus Geographic Information > Biology Theme CoRIS Theme Thesaurus EARTH SCIENCE > Biosphere > Aquatic Habitat > Water Column Habitat Theme CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Marine Biology > Fish Theme CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Ocean Acoustics > Acoustic Attenuation/Transmission > Bioacoustics > Fishes Theme NOS Data Explorer Topic Category Environmental Monitoring Theme 38kHz Theme Coral Theme ES60 Theme Fish Survey Theme Fisheries Acoustics Theme Hydrographic Acoustics Theme NOAA Theme Reef Theme Simard Theme Splitbeam Sonar Spatial CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > Texas > East Flower Garden Banks (27N093W0001) Spatial CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > Texas > West Flower Garden Banks (27N093W0002) Spatial CoRIS Place Thesaurus OCEAN BASIN > Atlantic Ocean > Gulf of Mexico > Flower Garden Banks > East Flower Garden Banks (27N093W0001) Spatial CoRIS Place Thesaurus OCEAN BASIN > Atlantic Ocean > Gulf of Mexico > Flower Garden Banks > West Flower Garden Banks (27N093W0002) Spatial East Flower Garden Banks Spatial Flower Garden Banks Spatial Flower Garden National Marine Sanctuary Spatial Gulf of Mexico Spatial West Flower Garden Banks National Centers for Coastal Ocean Science Silver Spring MD Data Set As Needed These data were prepared by an agency of the United States Government.

Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; Esri ArcGIS 10.1.0.3035 The fish acoustic data is for the East and West Banks for the Flower Garden National Marine Sanctuary. Surveyed predefined areas of the sanctuary in a variety of habitats. The scientific echosounder was calibrated using standard calibrations techniques(FOOTE et. al. 1981). All data was scrutinized and edited for bad data returns. Applied a tracking algorithmic to detect fish in the water column. All data analyses were conducted using Echoview 5.1 software. Not applicable 1 Acoustic data was collected aboard the R/V Manta using ES120-7C splitbeam transducer. The Kongsberg ES120-7C transducer was pole mounted aboard the R/V Manta. Kongsberg ES transceivers and Simard ES60 software was used in the data acquisition. 2012-01-01T00:00:00 2 Echoview 5.2 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. 2012-01-01T00:00:00 3 An acoustic processing script(V6.4) was used to calculate the density and size of fish through out the water column. Then projected(WGS84) in 100 square meter resolution ESRI shapefile. 2012-01-01T00:00:00 4 Arc Catalog was used to merge the daily shapefiles into one cruise shapefile. Metadata was added using arc catalog. 2012-01-01T00:00:00 41212 Entity gov.noaa.nmfs.inport:39215 Tyler Christensen 2017-04-05T12:51:15 SysAdmin InPortAdmin 2025-05-15T19:16:11 2017-09-13 National Centers for Coastal Ocean Science NCCOS 1002 Public No No 2017-09-13 1 Year 2018-09-13
