Results of seven hydrographic cruises into the Gulf of California during 1956 and 1957 show that the water mass there is characteristic of Equatorial Pacific water though modified by intensive evaporation in surface layers. The combination of wind regime and complicated topographical features plays a predominant role in circulation, upwelling, distribution of temperature, and other hydrographic factors. Seasonal changes are large....
