AB: Physical and biological data were gathered in Bay of La Paz, Southern Gulf of California, in summer, 2004. These include hydrographical data, ADP currents, backscattering signals, in vivo natural fluorescence, as well as, zooplankton samples. The topography of the 15°C shows a dome in the central part of the bay that becomes deeper towards the periphery suggesting the existence of a cyclonic eddy. The 35 salinity topography shows an uplift of 35 m. The eddy has a north-south diameter of approximately 35 km and cover almost all the bay. The zooplankton samples reveal the existence of 23 groups the most abundant were cladocera, copepods, siphonophores, chaetognaths and larvae of crustaceans. The zooplankton biomass presents higher values in the periphery of the eddy indicating an influence of the cyclonic circulation in their distribution.
