Description:

Abstract:

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 profiles capture the unsteady boundary layer that developed due to the tsunami-induced currents. They are useful for understanding the frictional interaction of the tsunami with the sea floor, as well as sediment transport produced by the tsunami.

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.

Process_Step:

Process_Description:

Data from pulse-coherent velocimeters must be corrected for ambiguity errors, which occur when velocities exceed the resolved range (Lacy and Sherwood, 2004). To assist with this correction, the Sontek PCADP measures velocities (called resolution velocities) at a single point at relatively short range, where greater velocities can be resolved, before collecting each profile. For these four bursts, we first corrected ambiguity errors in the resolution velocities, attributable to the high instantaneous speeds produced by the combination of surface waves and the tsunami. Then ambiguity errors in the velocity profiles were resolved as described in Lacy and Sherwood (2004), using the corrected rather than raw resolution velocities.
