Available in PDF, EPUB and Kindle. Book excerpt: The California Front, the boundary region between the Eastern North Pacific Central Water and the Transition Water, is approximately 170 mi wide, and is centered approximately 530 mi off the California Coast. (This region contains large anomalies in water structure that influence sound transmission.) The location of the maximum horizontal change in water properties was established from serial oceanographic stations, and the detail of thermal and current structures was obtained with a towed thermistor chain and attached current meters. The boundary is characterized by stronger than normal horizontal temperature (and salinity) gradients; large vertical changes in isotherm depths; temperature inversions; a large surface temperature gradient; and a thermocline separation. Temperature inversions produce sound channels above the level of increased temperature. Measured current shear shows relative current in the upper layers to be in a southerly direction on the eastern side of the boundary and in a westerly direction on the western side; however, current shear inside the boundary regions was in diverse directions.

Available in PDF, EPUB and Kindle. Book excerpt: Oceanic fronts have received relatively little attention in recent literature. The best overall summaries and oceanwide mapping of fronts are found in German works of the 1930's. The location and relative intensity of oceanic fronts at the surface are computed twice daily at Fleet Numerical Weather Central from sea-surface temperature analyses. The seasonal mean positions of the oceanic fronts in 1968 and their variations are presented in this paper. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This Topics volume is devoted to a study of sound propagation in the ocean. The effect of the interior of the ocean on underwater sound is analogous to the effect of a lens on light. The oceanic lens is related, as in light propagation, to the index of refraction of the medium. The latter is giv~n by the ratio of the sound frequency to the speed of sound in water, typi ca lly about 1500 m s -1. It is the vari ation of the sound speed due to changing temperature, density, salinity, and pres sure in the complex ocean environment which creates the lens effect. Many oceanic processes such as currents, tides, eddies (circulating, translating regions of wa ter), and internal waves (the wave-like structure of the oceanic density variabil ity) contri bute in turn to the changes in sound speed'. The net effect of the ocean lens is to trap and guide sound waves in a channel created by the lens. The trapped sound can then propagate thousands of miles in this oceanic waveguide. In addition to the propagation in the interior of the ocean, sound can propagate into and back out of the ocean bottom as well as scatter from the ocean surface. Just as the sound produced by a loudspeaker in a room is affected by the walls of the room, so the ocean boundaries and the material properties below the ocean bottom are essential ingredients in the problem.
