  Description: 
    Abstract: BPI Zones are derived from a focal mean analysis on bathymetry and slope.
      The grid is derived from gridded (5 m cell size) bathymetry and
      was created using the Benthic Terrain Modeler 3.0 (Beta 3).
      The bathymetry grid includes multibeam bathymetry from the
      Reson 8101 multibeam sonar aboar the NOAA Ship Oscar E. Sette collected as of
      May 2010 by the NOAA Coral Reef Ecosystem Division in depths between 10 and 300
      meters. These data complement multibeam data collected by the U.S. Naval Oceanographic
      Office at FDM during several test cruises, which are available from NOAA's National
      Geophysical Data Center.
    Purpose: The data were derived in support of NOAA Coral Reef Conservation
      Program goals. Goal 1 is to map all U.S. Coral Reef Ecosystems.
      This data set specifically addresses Objective 1 and 4: to develop
      high-resolution benthic maps and to characterize priority deep
      water reefs and associated habitats.  This derivative of bathymetry
      provides a GIS layer that may be used for benthic and essential fish
      habitat characterization, and for the study of geologic features.
      By combining the dataset with bathymetry, backscatter, other
      derivatives, and in situ data, they collectively compose benthic
      habitat maps which are designed to be used to understand and predict
      moderate depth (~20m to 150m) benthic habitats for different
      organisms that inhabit coral reef ecosystems.
    Supplemental_Information: Multibeam data were collected aboard the NOAA Ship Oscar Elton Sette, a 224’ (68 m) United States
      National Oceanographic and Atmospheric Administration research ship. The NOAA Ship
      Sette's survey sensors included a 240-kHz pole-mounted Reson 8101ER sonar, which provides
      bathymetry and imagery data, a TSS/Applanix POS/MV Model 320, which measures position,velocity, attitude and
      heading, and a Seabird SBE19 CTD used to measure sound velocity profiles.

      Process_Description: Bathymetric Position Index Zones were derived from the gridded
        multibeam bathymetry (clipped at 400 m) for Farallon de Medinilla, using the Benthic Terrain Modeler
        (BTM) Version 3.0 (beta) for ArcGIS10.1 Desktop (https://coast.noaa.gov/digitalcoast//tools/btm/).
        BPI Zones are derived from a broad-scale focal mean analysis of bathymetry and slope. After testing 3 different
        scalefactors, a scalefactor of 200 was chosen as best identifying broad scale
        zones, while minimizing noise and optimizing possible reef features
        Two ranges of slope define flat and slope: X < 5 degrees, and x > 5 degrees.
        There may be edge effects at the outer extent of the data.
