North Pacific Ocean. Central Pacific Transition Zone, R/V Thomas G. Thompson: 25 March - 3 May 1968. STD Data Report

摘要

During March and April 1968, scientists aboard the R/V Thomas G. Thompson studied the thermohaline and density structures in the subarctic-subtropical transition zone of the central North Pacific. Additional hydrographic sections were made north of Kahuka Point, Oahu. Of the 130 STD stations planned for this area, 127 were completed and 3 were lost because of weather. The primary objectives of the field study were: 1) to investigate the mesoscale thermohaline and density structures in long meridional high resolution sections across the subarctic and subtropical boundaries. 2) to determine the mesoscale signatures of the subarctic and subtropical fronts at the boundaries of the transition zone. 3) to study the mesoscale dynamic height and baroclinic flow structures across the transition zone. 4) to access the submesoscale thermohaline and baroclinic flow variability in the vicinity of the Hawaiian Ridge.
