“…Overall, both linear and nonlinear simulations include the mean near‐coastal poleward currents, which are basically the ocean response to the local nearshore positive wind stress curl (Figure 3), extending from northwest of the Acapulco region to the mouth of the Gulf of California (Figures 4 and 5). Badan‐Dangon et al [1989] and Badan‐Dangon [1998] invoked on the existence of poleward coastal currents in the region, which the authors named the Mexican Current. However, to the best of our knowledge, the only two pieces of evidence for the existence of these mean poleward coastal currents, reported in the literature, are (1) model results from NLOM (see Figure 1b from Zamudio et al [2001]), which were recently validated by (2) the direct observations of Lavin et al [2006].…”

“…The boundaries for the water masses were adapted from Durazo & Baumgartner (2002). Our change in the upper salinity limit for SAW (33.6 rather than 34 psu as in Durazo & Baumgartner (2002)) reflects the conditions found near the Mexico-U.S.A. border (Badan-Dangon et al (1989), also see Fig. 8 in Lynn & Simpson (1987)).…”

“…Congruous with this, various authors suggest the Inshore Current is a surfaced California Undercurrent (e.g. Lynn & Simpson, 1987;Badan-Dangon et al, 1989;Pares-Sierra & O'Brien, 1989).…”

The effects of the 1997-98 and 2002-04 El Niño on the upper waters in the continental shelf and slope regions off northwestern Baja California are explored with data from eight cruises taken in late spring from 1998 to 2004 and the summers of 1997 and 1998. Geostrophic velocities were calculated referenced to a specific volume anomaly surface separating the southward flowing California Current waters from the waters advected to the north by the California Undercurrent. The resulting fields show equatorward flow near the surface except in the summer of 1997, when a poleward jet was found in the upper 40 dbars. This shallow jet advected anomalously warm and salty waters characteristic of the 1997-98 El Niño, with its core found within 20-30 kms from the coast. By spring of 1998, the waters brought into the region by the jet had mixed across the pycnoline with the salty California Undercurrent waters below, resulting in high salinity levels on the density surfaces corresponding to the otherwise fresh California Current waters (25-26σ t ).

“…There is a compensatory slow inward flow in the central and eastern parts (Mascarenhas, Castro, Collins, & Durazo, ; Roden, ). The warm period, dominated by a slope current along the continental coasts (the Mexican Current) (Badan‐Dangon, Robles, & Garcia, ), has a compensatory flow on the west peninsular side. This current is responsible for the oligotrophic water intrusion from the PO into the GC and during its peak intensity it reaches the northern part of the GC and generates a cyclonic circulation in this zone (Lavín, Beier, Gómez‐Valdés, Godínez, & García, ; Zamudio et al., ).…”

Influence of environmental variability on distribution and relative abundance of baleen whales (suborder Mysticeti) in the Gulf of California

The Gulf of California (GC) is one of the most productive seas in the Pacific Ocean because of several oceanographic phenomena that support many marine mammal species, particularly of the cetacean order. The environmental variability of the GC was analysed during the cold and warm periods of 2005 and 2006 and its effects on the distribution and relative abundance of baleen whales using sea surface temperature (SST) and chlorophyll a (Chl a) concentration. Satellite image analysis allowed us to detect important differences in both Chl a concentration and SST including cold to warm periods, even between the two cold periods and between the two warm periods. The cold periods had the highest number of whales: 99 individuals in 2005 and 183 in 2006, which were distributed along the entire gulf. Fewer animals were recorded in the warm period: 46 individuals in 2005 and 30 in 2006, which were mainly distributed in the northern part of the gulf. We concluded that SST influenced the relative abundance of baleen whales while Chl a concentration influenced their distribution.
