%X Hydrographic and current observations were gathered during a 1997 cruise in the southern Gulf of California, off La Paz Bay, to study coastal circulation and the influence of El Bajo de Esp¨ªritu Santo (EBES) seamount on the local flow. We detect an unusual presence of equatorial surface water related to the El Ni o event of 1997-1998. In Farall¨®n basin we describe a 120 km diameter near-surface cyclonic eddy from ADCP current measurements, geostrophic calculations and satellite imagery. Flow measurements show an intense (> 0.5 m s-1) and narrow (25 km) coastal jet flowing north towards the interior of the Gulf along the Baja California coast. A Lagrangian analysis of the flow field over the seamount shows the coastal jet and the convergence of the impinging flows where bathymetry is important.
