OCEANOGRAPHIC DATA REPORT, SAN CLEMENTE ISLAND AREA, JULY AND AUGUST 1967

Abstract

The report presents oceanographic data collected during July and August 1967 aboard the USNS Davis (T-AGOR 5) in the San Clemente Island Deep Submergence Rescue Vehicle Test Range and Sea Lab III areas. The Deep-Towed Profiler records show two small valleys in the Sea Lab III area. The bottom's surface was predominately sand at the sites sampled. Nansen cast data show that the water column temperature decreases almost linearly below the thermocline. Although current speeds of 0.5 knots were recorded at the 100 to 260 fathom sites, the predominant current speeds varied from 0.0 to 0.2 knots. The near- bottom current at the 42 fathom site reached 0.7 knots with a mean speed of 0.5 knots. The current direction at the sites sampled reverses along an axis parallel to San Clemente Island. Bottom photographs show that the bottom is alternately smooth and flat, steep, and boulder strewn.
