Velocity and backscatter during two through-canyon flow events. a Map shows mooring locations with repeat mapping areas outlined in white. b ADCP-measured velocities capture the arrival of the 15 January 2016 and 1 September 2016 flows as they reach successive moorings within the canyon. Unresolved velocity readings are in white. Maximum ADCP-measured velocities (white numbers) and transit velocities (black numbers) are shown for comparison. c ADCP-measured backscatter, beginning 5 min before the arrival of the event, shows the evolution of the flow at each mooring. Echo Intensity Counts (EIC) are proportional to decibels. The ADCPs captured a 65 to 70 m range above the seafloor when the moorings were stable and upright. Ranges to seafloor decreased when the moorings were pulled downwards during events
