Summary

On February 27, 2010, a tsunami originating near Chile arrived in Monterey Bay, California. This data release comprises two hours of pressure and near-bed velocity data spanning the largest tsunami waves. At the time, the U.S. Geological Survey Pacific Coastal and Marine Science Center had a remotely-controlled instrumented platform deployed adjacent to the Santa Cruz Municipal Wharf (mean depth 9 m) for collecting hydrodynamic and sediment transport data. In anticipation of the arrival of the tsunami, sampling was changed to better capture the event. Pressure and near-bed velocity profiles were measured at 1 Hz for 25 minutes every half hour. The velocities are influenced by surface waves, tsunami waves, and tidal currents. The velocity [...]

Purpose

These data were collected to measure conditions near the sea floor on the inner shelf during the arrival of a remote tsunami in Monterey Bay. Purposes for the data collection included determining sediment transport generated by the tsunami, and for producing a data set to test numerical models of tsunami flows and their interaction with the sea floor. These data are intended for science researchers, students, policy makers, and the general public.
