Note for Phase 2:
On February 29, 2008, IORGC/JAMSTEC deployed the second surface buoy JKEO2 at JKEO site (38-04.82' N, 146-25.21' E) during MR07-06 Leg 3 cruise. JKEO2 buoy is a newly designed one named as K-TRITON which is based on m-TRITON buoy developed by MARITEC/JAMSTEC. JKEO2 buoy was recovered on September 5, 2008. The daily average and hourly meteorological and oceanic data retrieved from recovered JKEO2 buoy system are publicly available in this web page. Spot values of high resolution buoy location fixed opportunistically by ARGOS are also available in this web page.

1) From March 6, real-time long wave radiation data had been wrong value.

2) From April 15, real-time oceanic data at 20 m and 200 m depths were unstable due to damages at wire cable caused by the long-line fishing gears.

3) From May 12, real time wind sensor data were unstable.

4) From May 28, JKEO2 has stopped transmitting all observation data due to loss of ARGOS Antenna.

5) JKEO2 was recovered on September 5, 2008 on board of R/V Kaiyo during her cruise KY08-09.

Acknowledgement:

We appreciate very much the R/V Wakataka-Maru and Chief Scientist Dr. Shinichi Ito, at Tohoku National Fisheries Research Institute, Fisheries Research Agency, for their help in examine the state of the buoy on June 3, only 5 days after the quit of data transmission from JKEO2.
