Figure 4. Zonal (top) and meridional (middle) geostrophic velocities as well as geostrophic current magnitudes (bottom) estimated from AVISO (black lines) and AVISO+TG (red lines) fields at 44.625°N, 124.375°W.
Also shown are zonal (top) and meridional (middle) current velocities as well as current magnitudes (bottom) as measured by the NH-10 ADCP (44.64°N, 124.3°W) at 16.5 m depth (blue lines). The mean value for each zonal and meridional time series, for the period presented here, was removed.
