Summary of Activity and Data Gathered: 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 Surveys 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).
