What does this data set describe?

Title:
NOAA-NMFS, Galveston Laboratory Essential Fish Habitat Project data
Abstract:
"The Magnuson-Stevens Fishery Conservation and Management Act of 1996 requires the regional Fishery Management Councils and the Secretary of Commerce to describe and identify Essential Fish Habitat (EFH) for species under federal Fishery Management Plans. Essential Fish Habitat is defined in the Magnuson-Stevens Act as "those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity." The word "fish" in the previous sentence includes finfish, crabs, shrimp, and lobsters in the Gulf of Mexico. By identifying EFH, we can protect these habitats and restore them if they become damaged. The Fishery Ecology Branch developed a web site to support EFH efforts of the Gulf of Mexico Fishery Management Council. Maps and information are presented for use in identifying EFH in the Gulf of Mexico using relative abundance estimates for managed fish species. These data were obtained from the Estuarine Living Marine Resources (ELMR) database developed by the National Ocean Service (NOS). The ELMR database was substantially upgraded by NOS to support of this EFH effort."

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):

      • Entity point (173)

    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 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1927.
      The ellipsoid used is Clarke 1866.
      The semi-major axis of the ellipsoid used is 6378206.400000.
      The flattening of the ellipsoid used is 1/294.978698.
