    "descript": "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.",

Distributions are records of currents, physical properties, or biogeochemical water properties, often based on shipboard surveys or coastal monitoring programs, and maps of currents or water property climatology, which indicate the expected locations of features under present conditions or apply a classification structure like that of CMECS. Assessments are data that provide information about the ecological or economic values, impacts, drivers, connections, or functions of water column features in their present distributions. Predictions are the results of models projecting future changes to currents or other persistent oceanographic features (for example, clines, stratification, connectivity, linkages, and zones of separation) due to climate change, ice-cap melt, and changing freshwater inputs; models predicting the ecological or economic impacts of these changes; and scenario-testing models comparing ecological or economic outcomes of different management actions."
