Abstract
Sea level variations and currents on the Oregon continental shelf exhibit wavelike characteristics in a frequency band from approximately 0.15 to 0.45 cycle per day (cpd). Shelf wave dispersion curves and eigenfunctions for the Oregon continental shelf profile computed using a numerical technique are compared with a low-frequency (∼0.03–0.75 cpd) spectral analysis of the current, sea level, and atmospheric pressure records. In a narrow band around 0.22 cpd the current, sea level relationship is consistent with the predicted values for free barotropic continental shelf waves.
