Abstract:
These are depth lines (isobaths) derived from NOAA bathymetry data at 20 fathoms (36 meters, 120 feet), 50 fathoms (91 meters, 300 feet), and 100 fathoms (183 meters, 600 feet).
Purpose: Created for general reference.

Attribute_Accuracy:
Attribute_Accuracy_Report: n/a
Logical_Consistency_Report: No checks for logical consistency have been done.
Completeness_Report:
This only contains the single longest contour at these depths. Numerous smaller contours were omitted. Also, because the units of the source bathymetry data were in meters the selected depth was rounded to the nearest meter. 100 fathoms (182.9 meters) is represented by a 183 meter isobath; 50 fathoms (91.44 meters) is represented by a 91 meter isobath; 20 fathoms (36.5 meters) is represented by a 36 meter isobath.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
This line was derived from 83 meter resolution raster bathymetry data. Horizontal accuracy varies depending on the number of soundings used to derive the bathymetry data in any given area.
