The summer hydrography of the Gulf of Mexico is examined on the basis of R/V Alaminos Cruise 69-A-10 during July 1969, and 127 stations occupied by the USNS Kane during that same summer. The T-S relationships observed indicate three water masses: (1) a single uniform deep-water system; (2) inflowing warmer water of Caribbean type with a high salinity maximum at the Subtropical Underwater core; and (3) Gulf water with a reduced salinity maximum. The waters of the surface mixed layer showed spatial differences reflecting local conditions of inflow and runoff. The horizontal current pattern has been inferred from the depth distribution of the 22°C isothermal surface, from the lateral distribution of salinity at the Subtropical Underwater core, and from the dynamic topography of the sea surface relative to the 750-db surface. During July, two detached rings, a young ring in the north central gulf and the remnant of an older ring in the far western gulf, were present.
