The Kuroshio off Southern Japan: Analysis of Data from the ASUKA Study
(ASUKA: The Affiliated Surveys of the Kuroshio off Ashizuri-Misaki)
Field Program:   1993-1995
Principal Investigator:   Mark Wimbush, University of Rhode Island
Goal:   Determining and understanding Kuroshio and Kuroshio Countercurrent transports
of volume, heat, and salt and their fluctuations on time scales of days to years.
Funding for this project was supplied by the Office of Naval Research
Geographic locations of principal ASUKA measurements.
Solid circles (large or small) mark sites where hydrographic
profiles were usually taken. The larger solid circles also indicate
the sites of IES's. Bull's eyes are current-meter-mooring sites.
Current-meter moorings with asterisks (CM2 and CM4) were
topped by upward-looking ADCP's.
Solid line indicates the main ASUKA line. The T/P track is parallel to
this line and lies approximately 8 km to the west-southwest.
Lower panel shows a sketch of the mean Kuroshio path and
recirculation in this region.
