Hydrographic variability in Bahia Vizcaino, Baja California, Mexico

Abstract

The outstanding hydrographic variations in Bahia Vizcaino were analyzed from temperature, salinity and dissolved oxygen data collected during the ECONER-0391 oceanographic cruise (March 18-22 1991) and from similar data obtained from a data bank (1960-1968). The main processes affecting the hydrographic variability in the bay were: the annual upwelling event, the seasonal warming and cooling, the water advection from the upwelling period (September), the convergence of waters to the south of the bay and the intrusions of the Subarctic Pacific Water Mass and Equatorial Transformed Water Mass. -from Authors
