Abstract : During January and February 1974 scientists aboard the R/V Thomas G. Thompson studied the thermohaline and density structures in the subtropical frontal zone of the central North Pacific. Additional hydrographic sections were made from the mouth of the Columbia River to the working are area and from the working area to the Hawaiian Islands. Of the 261 CTD stations planned, 257 were completed and 4 were lost due to weather. The primary objectives of the field study in the central North Pacific were: 1) to investigate the three dimensional thermohaline and density structure in the subtropical frontal zone by means of high resolution sections. 2) to determine the mesoscale baroclinic flow field in the subtropical frontal zone. 3) to study the mesoscale dynamic height perturbations and the mesoscale thermohaline structure along 1400 km long sections north and east of Hawaii. 4) to assess the mesoscale thermohaline and baroclinic flow variability in the vicinity of the Hawaiian ridge. Keywords: Oceanographic data; Sea water; Electrical conductivity; Temperature; Depth; Salinity; Oceanographic fronts; Winter.
