Overview | Sections | Photos

This was the second leg of the mid-experiment cruise for KESS, conducted aboard R/V Revelle. The cruise entailed 29 working days at sea, June 17 - July 17, 2005, departing from and returning to Yokohama, Japan. The main objectives were as follows:

1. service an array of 46 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. collect by acoustic telemetry (simultaneous with most CTDs) the previous year's records of daily-processed (τ, P, (u, v)) data;
4. 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.
5. launch eight Apex-ARGO profiling floats
6. launch ten NOAA surface drifters
7. collect intensive atmospheric profiles of temperature, humidity, wind velocity versus pressure across the Kuroshio Extension using 120 weather balloons with radiosondes
8. replaced one radiometer sensor on the NOAA KEO meteorological buoy
