Gravity range, gravity range contour maps, gravity range bathymetry
313 bottom gravity measurements were made over a 200 square nautical
mile area on the Continental Shelf approximately 20 miles due west of Cape
Flattery, WA. Observations were made at one nautical mile intervals to establish
a test range for evaluating the accuracy and performance of underway sea-surface
gravimeters. In addition, 499 bottom gravity measurements were made on the
Continental Shelf between the 5 and 100 fathom isobaths from Cape Flattery, WA,
to Monterey Bay, ca. Measurements were made at 5 mile intervals as part of the
National Ocean Survey's marine gravity program. 32 sea-fix shore stations were
established. The shore station pairing for the gravity test range included EPI
Mukkaw (north station) and Quill RMS (south station).
