  1. Review of present TRITON project, and The plan of Indian Ocean mooring array 1. TRITON data web 2. TRITON operation status 3. Japan EOS Promotion Program, and development of mini TRITON Yoshifumi Kuroda, Kentaro Ando, Yukio Masumoto and Keisuke Mizuno Japan Agency for Marine-Earth Science and Technology Center (JAMSTEC)

  2. TRITON web page http://www.jamstec.go.jp/jamstec/TRITON/real_time/ ・ New TRITON Data Management System and new TRITON web page has started in 2005 ・ hourly data (real time) are available now ・Example of TRITON data display ８N,156E (longest TRITON record)

  3. What TRITON accomplished ・ Continually monitors ENSO in the Pacific as the TAO/TRITON array since January 2000. ・ Started the two Indian Ocean TRITON buoy deployment since October 2001 as a pilot study. TRITON array enables to investigate air-sea interaction and water mass change in the Indo-Pacific warm pool with salinity sensors. ・Developed the data management and data distribution system. ・Built a marine technician team for mooring work, data calibration and data processing. ・Built partnership with BPPT, Indonesia which enabled the buoy recovery operation by Indonesian Research Vessel in 2003.

  4. Development of TRITON buoy array from 1998 to 2002 March, 1998 March, 1999 March, 2000 August, 2002 March, 2001 March, 2002 Purposes; 1. Monitoring ENSO as TAO/TRITON array 2. Air-sea interaction over the Pacific and Indian Ocean warm pool 3. Variability of temperature and salinity in the warm pool - Improvement of the predictability of El Nino

  5. Seventeen (17) TRITON buoys have been maintained since November 2002

  6. New JAMSTEC Budget Initiative Funded ・JAMSTEC received a new 5-year budget starting in JFY2005 for promoting the Indian Ocean mooring array as a part of "JEPP: Japan EOS (Earth Observation System) Promotion Program" related GEOSS. ・This fund will enable the development of new small size TRITON buoy (JEPP buoy) and the continuation of the present TRITON sites in the Indian Ocean. Current array up to 2007 Grand design

  11. Relation with OceanSites mini-TRITON Present TRITON Easy operation ①　Cut cost below half of present construction and maintenance ②　Make small and light to enable maintenance by ships in coastal countries ③　Improve data processor reliability and future extension ①　Indian Ocean mooring array by JEPP ②　Replace present TRITON array in future Next generation mooring array Super site TRITON ①Contribute to GEOSS Earth Observing System. ② Monitor and study tEl Nino, and Dipole Mode Phenomena. High precision, interdisciplinary sensors Problems ①　Require large vessel for maintenance, ②　High costs for construction and maintenance, ③　Parts getting old, ④ Old fashioned data transmission system. ①High precision heat and fresh water flux measurements ②CO2 measurement　 ③Utilize present TRITON platform Super site TRITON
