Summary
|
|
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).
