Sea Levels and Metered Currents off Central California.
Abstract
Sea levels from two locations, the alongshore sea level gradient and direct measurement of currents by moored current meters are examined and discussed. The observations were made off the central California coast during the Davidson Current period 1978-9. Analysis for spectral variance of hourly and low pass filtered sea levels, alongshore sea level gradient and alongshore and cross shelf currents was performed. Comparison of spectral estimates of low pass filtered data indicate that current and sea level gradient energy distributions are in close agreement. This is interpreted to suggest that a relationship may exist between the observed currents and the longshore sea level gradient. In contrast, the low pass filtered sea level spectrum indicates energy concentrated at lower frequencies than was observed for currents. (Author)
