North Pacific Ocean. Northwest Pacific Transition Zone, R/V Thomas G. Thompson: 19 March - 1 May 1971. STD Data Report

摘要

During March and April 1971 scientists aboard the R/V Thomas G. Thompson studied the thermohaline and density structures in the subarctic-subtropical transition zone of the northwestern Pacific. A total of 270 STD stations were taken. Heavy weather prevented taking stations north of latitude 43 N. The primary objectives of the field study in the northwestern Pacific were: 1) to investigate the mesoscale thermohaline and density structures in 2700 km long high resolution sections across the subarctic and subtropical boundaries. 2) to determine the mesoscale signatures of the subarctic and subtropical fronts at the end of the winter season. 3) to study the mesoscale dynamic height and baroclinic flow structures across the subarctic-subtropical transition zone. 4) to assess the thermohaline variability in the Oyashio region off northeastern Japan.
