Abstract:

Eighty underwater gravity measurements were made in northern Monterey Bay in water depths from 38 feet to 456 feet. In addition, seven shoreline stations were occupied just above the swash zone. A complete Bouguer anomaly map was drawn and tied in with the previous land surveys and with one covering the southern half of the bay. The isolines of the complete Bouguer anomaly indicate the relative vertical position of the basement complex Santa Lucia granite and the overlying sedimentary strata of the Purisma and Monterey Formations. Analysis gives evidence of a basement complex ridge in the north bay. A two-dimensional model of the depth to basement along a representative transect shows further evidence of the ridge. New evidence for an extended Monterey Canyon fault is presented. Modified author abstract
