  1. Tropical Indian Ocean Moored Buoy Arrays M. J. McPhaden, NOAA/PMEL Chairman CLIVAR/JCOMM Tropical Moored Buoy Implementation Panel Objectives-- Review of existing efforts (moorings and broader observing system). Continue planning for sustained array based on science needs and potential applications First Session of the Indian Ocean Panel 18-20 February 2004 Pune, India

  2. Indian Ocean IOGOOS, Mauritius, 4-8 November 2002 (co-sponsored by CLIVAR) Oceans and Climate Workshop Goal: “…to identify actions required to develop an Implementation Plan for the Indian Ocean Global Ocean Observing System (IOGOOS), building on the SOCIO Workshop, meetings of the Climate Variability (CLIVAR) Asian/Australian Monsoon Panel, and the Global Ocean Data Acquisition Experiment (GODAE) Science Team…”

  3. Indian Ocean Science Drivers • Seasonal monsoon variability • Intraseasonal oscillations • Indian Ocean dipole mode • Decadal warming trends • Indonesian throughflow • Subtropical/tropical overturning cells • Deep meridional overturning

  4. Indian Ocean Observational Status: • Satellite observations of sea level, SST, wind and ocean color are key elements of the Indian Ocean Observing System. • Skeletal existing networks in place for many years; substantial recent progress in implementation of in situ observations (Argo, moorings, drifters, XBTs, etc).

  5. Indian Ocean XBTs Dec ‘02 Drifters, Jan ‘03 Argo Floats, Feb ‘03

  6. Indian Ocean Not shown: • US interests in equatorial and BoB moorings • Plans for 40 deep ocean moorings north of 5°N (NIOT) • Madagascar Channel moorings (Dutch) Masumoto et al, 2002

  7. Indian Ocean JAMSTEC ADCP mooring 0°, 90°E Masumoto et al, 2002

  8. Indian Ocean Science & Implementation Challenges • Array design(s) • Funding • Ship time • Fishing vandalism • Measurement standards • Data management • International coordination
