Abstract : During September and October 1975 scientists aboard the R/V Thomas G. Thompson studied the thermohaline and density structures in the subarctic frontal area to the central North Pacific. In addition, high resolution hydrographic sections were made from Cape Flattery to the working area and from the working area to Kahuku Point, Oahu. Of the 287 CTD stations planned, 286 were completed, one was lost due to weather. The primary objectives of the field study were: 1) to investigate the three-dimensional thermohaline and density structure in the subarctic frontal zone by means of high resolution sections. 2) to determine the mesoscale baroclinic flow field in the subarctic frontal zone. 3) to study the mesoscale dynamic height perturbations and the mesoscale thermohaline structure along a 2700 km long section north of Oahu. 4) to assess the mesoscale thermohaline and baroclinic flow variability in the vicinity of the Hawaiian Ridge. Keywords: Oceanographic fronts; Sea Water; Electrical conductivity; Autumn; Salinity temperature depth; Oceanographic data.
