This was the second leg of the final cruise for KESS, conducted aboard R/V Melville. The cruise entailed 35 working days at sea, June 1 – July 5, 2006, departing from and returning to Yokohama, Japan. The main objectives were as follows:

1. recover an array of moored CPIES that had been deployed in the Kuroshio Extension in Summer 2004, on a grid spanning from the southern recirculation region to the mixed water regime with site locations coordinated with Jason satellite altimeter groundtracks;
2. collect deep CTD profiles at each CPIES site for calibration purposes;
3. conduct a closely-resolved feature survey of a Kuroshio meander / ring using CTDs to 1500 m and the deep-reaching (700 – 900+ m) Doppler current profiling capabilities of R/V Revelle.
4. collect intensive atmospheric profiles of temperature, humidity, wind velocity versus pressure across the Kuroshio Extension using xx weather balloons with radiosondes
5. launch five NOAA surface drifters
