Abstract
Turbidity currents are thought to be the main mechanism to move ~ 500,000m3 of sediments annually from the head of the Monterey Submarine Canyon, to the deep-sea fan. Indirect evidence has shown frequent occurrences of such turbidity currents in the canyon, but the dynamic properties of the turbidity currents such as maximum speed, duration and dimensions are still unknown. Here we present the first-ever in-situ measurements of velocity profiles of four turbidity currents whose maximum along-canyon velocity reached 190cm/s. Two turbidity currents coincided with storms that produced the higest swells and the biggest stream flows during the year-long deployment.
