  Description:
    Abstract:
      A multi-sensor survey was conducted in 1991 along the
      Endeauvour Segment. These data contain point files that
      include information related to navigation, vehicle
      attitude, the environment, and vehicle status. The
      processed point data was converted into ArcInfo format and
      cleaned of fliers. Line coverages were constructed from the
      point files.
    Purpose:
      These data were created to aid in the desription and
      discovery of the workings of the hydrothermal vent system
      found on the Endeavour Segment of the Juan de Fuca Ridge.

    The positional accuracy of the data contained in this
    coverage depends primarily on the accuracy of the
    navigation employed during data collection. These data were
    originally collected using an accoustic transponder network
    registered to GPS with Selective Availability (SA) on, and therefore
    may be variable.

DATA_QUALITY_INFORMATION

  Attribute_Accuracy:
    Attribute_Accuracy_Report:
      Chain-node topology.
  Logical_Consistency_Report:
    The locational information for these data are related to
    positional accuracy.
  Completeness_Report:
    Navigational data were analyzed for erroneous fixes, i.e.
    points that were obvious outliers were removed.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report:
        These data were logged by the DSRV Alvin using an in-hull
        navigation system. This system uses the travel time of
        accoustic energy from the submersible to the transponders
        and back to the submersible (rather than
        submersible-transponder-ship). The accuracy is
        +/- 1.0 meters.
    Vertical_Positional_Accuracy:
      Vertical_Positional_Accuracy_Report:
        Vertical control was provided by the pressure sensor and
        altimeter readings on the submersible. The vertical
        accuracy is +/- 0.5 meters.

    Process_Step:
      Process_Description:
        1. The submersible was navigated with a long-baseline
        transponder net. The sub's position was monitored by
        surface controllers and by the pilot and scientists in the
        sphere with the in-sub program.
        2. Positions were reported in ALVIN X/Y (meters)
        coordinates based on a grid which has its origin at 47.8939
        degrees latitude and -129.16451667 degrees longitude (to
        the south and west of the transponders and dive region for each
        transponder net).
        3. ALVIN positions were then converted into Lat/Long
        measurements with the program
        "xy2ll.kf"(\\bromide.ocean.washington.edu\usr\local\bin).
        4. Data were then entered into GIS.
