Title:
Acropora Presence/Absence in Surveyed Waters of Florida 1996-2008
Abstract:
On May 9, 2006, NOAA's National Marine Fisheries Service (NOAA Fisheries Service) listed staghorn and elkhorn corals (Acropora cervicornis and A. palmata) as threatened under the Endangered Species Act (ESA). These two species qualified as ESA threatened species because there was evidence they have undergone substantial declines in abundance (from historic levels) throughout their ranges. NOAA Fisheries Service is now seeking to determine the extant spatial distribution of these two species throughout the Caribbean Sea and Atlantic Ocean to aid in the management and regulatory activities related to ESA listing. These data represent the potential locations of presence or absence for elkhorn coral (Acropora palmata) and staghorn coral (A. cervicornis).
Supplemental_Information:
Data submitted by investigators are converted into a series of flat files in dbf format with indices that show presence and true absence (where possible) of A. cervicornis and A. palmata for each U.S. State or Territory. True absence of an Acropora species means that an active search was made to locate the coral at the given GPS coordinates, but the species were not found there.

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000001. Longitudes are given to the nearest 0.000001. Latitude and longitude values are specified in Decimal Degrees.

      The horizontal datum used is D_WGS_1984.
      The ellipsoid used is WGS_1984.
      The semi-major axis of the ellipsoid used is 6378137.000000.

Why was the data set created?

The overarching goal is to provide NOAA Fisheries Service with information on the extant spatial distribution of acroporid corals throughout the Atlantic Ocean to aid in management and regulatory activities related to their Endangered Species Act (ESA) listing. The purpose of these data is to visually represent the potential locations of presence or absence of Acropora spp. for GIS analysis and display.


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: 30-Apr-2008 (process 1 of 1)
    digital GIS shapefiles were developed using ESRI ArcGIS software to show the distribution of A. cervicornis and A. palmata separately in each location where we have data. Data submitted by investigators are converted into a series of flat files in dbf format with indices that show presence and true absence (where possible) of A. cervicornis and A. palmata for each U.S. State or Territory.
