Abstract

Shore-based high-frequency Doppler radar observations collected in Monterey Bay between 1999 and 2001 are utilized for the reconstruction of high-resolution surface currents: mesoscale and submesoscale ageostrophic spiral eddies, eddy dipoles, eddy tripoles and multi-eddy systems with lifetimes about 4-12 hours (sub-inertial periods). Our analysis demonstrates topography nature of all these eddies because of rectification of tides in the submarine canyon system. Spiral mesoscale eddies generated in the head of Monterey and Soquel Canyons have induced strong alongshore water transport qualified as Stokes drift
