Book Description
A study was made of the thermal structure of the upper 800 feet of the sea by towing the NEL thermistor chain in deep water between San Diego, California, and Honolulu, Hawaii. The median vertical (slope) in temperature sections proved to be 0 degress 16 min. and the 70-percentile (slope), 0 degrees 30 min., and the significant high frequency peaks in the power spectrum of isotherm depths are more numerous in the central part of the section between Hawaii and California. (Author).

Book Description
Time-dependent horizontal-temperature gradients were computed from vertical-temperature cross sections taken with the towed thermistor chain in 17 areas of the eastern North Pacific. The horizontal gradients were found to be generally smaller than the vertical gradients by two orders of magnitude. The horizontal-gradient field alternated regularly in sign, implying a dominant frequency of internal waves or convection cells (with a corresponding wavelength of 0.72 nautical mile). The horizontal gradient in the thermocline can be predicted from the measured vertical gradient by means of the equation: dT/dx = 0.0047(dT/dz) to the 0.71 power. On the basis of these results, plus a single bathythermograph lowering, a simplified predictive model of the horizontal-temperature gradients was constructed. (Author).

Book Description
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.

Book Description
The sea temperature structure of the upper layers was investigated by the use of a thermistor chain towed off the southern extremity of Baja California, Mexico, which revealed vertical and horizontal motion, large scale turbulence, and possible Doppler effects. The thermoclines were categorized in four types, smooth, normal, rough, and irregular. The power spectrum of vertical oscillation in the thermocline showed small peaks at wavelengths of 0.3 and 0.7 mile. The slopes of isotherms were determined from a study of over 65,000 data samplings. (Author).
