Abstract	With collaborated research efforts in the regional coastal ocean observing systems (SCCOOS, CeNCOOS, and NANOOS) off the U.S. West Coast (USWC), the nearly completed high-frequency radar (HFR) network provides an unprecedented capability to monitor and understand coastal ocean dynamics and phenomenology through hourly surface current measurements at up to 1 km resolution. The dynamics of the surface currents off the USWC are governed by tides, winds, Coriolis force, low-frequency pressure gradients (less than 0.4 cycles per day (cpd)), and nonlinear interactions of those forces. The HFR surface currents resolve coastal surface ocean variability continuously across scales from sub-mesoscale to mesoscale (O(1) km to O(1000) km). Their spectra decay with k-2 at high wave number (less than 100 km) in agreement with theoretical sub-mesoscale spectra below the observational limits of present-day satellite altimeters.
