      Title: 10-meter Bathymetry Polygons off Oregon for Essential Fish Habitat (EFH)
      Geospatial_Data_Presentation_Form: vector digital data
  Description:
    Abstract: These data depict 10-meter depth zone polygons in the marine areas off Oregon State. 
    Purpose: These data were developed for Pacific States Marine Fisheries Commission in cooperation with the National Marine Fisheries Service Northwest Region and the Pacific Fishery Management Council in support of an Environmental Impact Statement (EIS) to consider the designation and conservation of Essential Fish Habitat (EFH) for Pacific Coast Groundfish. These data were consolidated and integrated in a GIS format to support spatially explicit groundfish habitat modelling and impacts assessment on a coastwide scale.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: All depth zone polygons were queried to ensure that the difference between the maximum and minimum depth values was exactly 10 meters.  Depth values were visually assessed by comparing to source contour data and shaded according to depth ranges.  One polygon was found to have an erroneous minimum value, and corrected.
  Logical_Consistency_Report: Source contour data were developed from multiple instruments and data sources with a large range of sounding point densities.  The 100-meter resolution grid used to create source contours, was created by combining and resampling sounding data using a natural-neighbor gridding scheme. 
  Completeness_Report: Data are comprehensive for the spatial extent
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: Horizontal accuracy was not assessed, so the positional accuracy is unknown.  Source contour data were created from a 100-meter resolution grid.
    Vertical_Positional_Accuracy:
      Vertical_Positional_Accuracy_Report: Vertical accuracy was not assessed, so the vertical accuracy is unknown.

    Process_Step:
      Process_Description:
        (1) Because depth polygons need to be continuous for West Coast EFH study area, it was necessary to manually extend the arcs at the north end of the Oregon contour data to meet the southern boundary of the Washington State contour data.  The gap between the two data sets was approximately 150 meters.  Approximately 450 arcs were extended with ArcInfo EXTEND command or manually in ArcEdit.  Oregon data was chosen to be extended because it was assumed to be more accurated than the Washington data.
        (2) Contour lines were clipped and merged with a box used to create an outer boundary for depth zone polygons.  In addition, there were some artifacts along the deeper edge of the contour data, assumed to be caused by values of zero (instead of null) outside the contour area of interest.  The clipping box removed these edge areas.
        (3) A series of AML programs were used to assign the depth values of the adjacent contour lines to the minimum and maximum depth attributes of each polygon.  If the polygon had only one adjacent contour line, the adjacent/surrounding polygon was used to determine whether the inner polygon was a high or low point in the relief and the maximum or minimum depth zone value was assigned accordingly.
        (4) Projected Oregon depth zone polygon data from UTM Zone 10, WGS-84 to West Coast Albers projection
