AN INVESTIGATION OF NEAR-BOTTOM CURRENTS IN THE MONTEREY SUBMARINE CANYON.

Abstract

An investigation of near-bottom currents in the head of Monterey Submarine Canyon was conducted between March 1967 and May 1968. Continuous observations of water temperature, current speed and direction were obtained over periods ranging from 5 hours to 162 hours using an in situ Savonius rotor current measuring system. Basic statistical parameters and power spectra were calculated for each record. These revealed an average current speed of about 0.23 knot (standard deviation of 0.17 knot), and a current direction which indicates flow reversals predominantly along the canyon axis. Current and water temperature oscillations indicated a strong semidiurnal component. Water temperature changes also showed seasonal variation that agrees with the seasonal means of the region. Current speeds as high as 1 knot were measured. (Author)
