Abstract : USS SAN PABLO cruise data of July 1963 (a repeated grid of 30 stations within a 100-mile square centered at 36 deg 30 min N, 66 deg 30 min W) are analyzed to determine horizontal conductivity effects on thermal structure. Temperature changes occurred in layers from the surface to a depth of nearly 1,750 meters. Separation of data into space and time variability was simple. Space variability remained large after compensation for diurnal effects; after removal of diurnal effects, space variation was represented by four characteristic vertical temperature and salinity structures. All of the characteristic structures were present on the initial survey, and three were present during the second survey. These microstructures were all within the classification of North Atlantic Central Water. Estimates of horizontal eddy conductivity effects indicated that eddy conduction could have caused all of the temperature change observed in the vertical structure between surveys. The eddy coefficient, however, appeared to be unreasonably large for depths greater than about 15 meters. (Author)
