Seafloor Rocks and Sediments of the Continental Shelf From Monterey Bay to Point Sur, California

By Stephen L. Eittreim, Roberto J. Anima, Andrew J. Stevenson, and Florence L. Wong

2000

Image of the geologic map
This map of the Central California seafloor shows the extensive outcrops of Santa Cruz Mudstone (brown color), Purisima Formation (red), and Monterey Formation (green) plus other rock units exposed on the continental shelf.

Introduction

Acoustic swath mapping of the greater Monterey Bay area continental shelf from Point Año Nuevo to Point Sur reveals complex patterns of rock outcrops on the shelf, and coarse sand bodies that occur in distinct depressions on the inner and mid-shelves. This publication portrays the seafloor components in a 36- by 48-inch map sheet at 1:100,000 scale. The digital database for the interpreted geology and other digital files are listed below and available for download. The explanatory text appears on the map sheet and a copy (mf2345.txt) is included below.
