Benthic Grab Sample

NOAA Coastal Services Center

Details

  • Developed in close cooperation with state and local partners to ensure high degree of accuracy and applicability
  • Organized according to the Florida System for Classification of Habitats in Estuarine and Marine Environments (SCHEME) and classified using the Wentworth system
  • Analyzed by grain-size distribution and chemical constituents as determined through laboratory analysis
  • Evaluated by individual species counts and taxonomic analysis
  • Contain a record of all observed organisms to a lowest practical identification level (LPIL)  

Notes and Limitations: Benthic and sediment grab point data are normally intended to identify specific sediment and biological characteristics and are collected to complement other sampling or mapping efforts. The data are collected in a systematic pattern distributed through the project area and require some interpolation to generate a comprehensive data set. Interpolations of these data should be used with caution due to potentially large non-sampled areas that are present within the output data. Users are encouraged to develop or obtain higher detail data for non-sampled areas within an interpolated output.
