Bottom current measurements were taken in the head of Monterey Submarine Canyon in a water depth of 130 meters (72 fathoms) utilizing an Ekman current meter placed 480 centimeters (15.7 feet) above the bottom. Currents were observed to follow the canyon axes, and flow was seaward (down-canyon) on the rising tide and coastward (up-canyon) on the falling tide. Current speed was sometimes fairly steady and other times variable. It ranged between 0 and 41 centimeters per second (0 to 0.8 knot) and had a median speed of 10 cm/sec (0.2 knot). The six hours centered around low tide generally had considerably stronger currents than the similar period of time centered around high tide. (Author).
