The purpose of this report is to present and briefly describe ship-board and laboratory data for a U.S. Geological Survey (USGS) research cruise aboard the RV Farnella that took place December 3–21, 1987 (cruise F7-87-SC). The purpose of the cruise was to survey seamounts and ferromanganese crusts within and near the U.S. Exclusive Economic Zone (EEZ) off California. Eight seamounts were studied—Rodriguez, San Marcos, Adam, Hoss, Little Joe, Ben, Flint, and Jasper. A geophysical survey of Jasper Seamount took place, but that seamount was not sampled; whereas Adam and Hoss Seamounts were sampled, but not surveyed with geophysics lines.
