Three days of simulaneous near-surface current measurements made by Coastal Ocean Dynamics Applications Radar (CODAR) and surface-moored Vector-Averaging Current Meters (VACM) in the Strait of Juan de Fuca are compared. The study focuses on the mean flow and tidal components that contained approximately 79% of the kinetic energy. The mean speed and direction difference were less than 7 cm/s and 10/sup 0/, respectively. The K/sub 1/ and M/sub 2/ tidal constituents agreed to within 14 cm/s with a mean difference of 5.2 cm/s. This study demonstrates that CODAR yields estimates of the near-surface currents that are comparable with conventional VACM arrays to 10-15 cm/s.
