  1. Report of theTropical Moored Buoy Implementation Panel to the 22nd Session of the Data Buoy Cooperation Panel October 16-20, 2006San Diego, United States

  2. Current ConditionsSST is warmer than normal across the equatorial PacificThermocline is deeper than normal in eastern Pacific.

  3. EL NIÑO/SOUTHERN OSCILLATION (ENSO) DIAGNOSTIC DISCUSSION (CLIMATE PREDICTION CENTER/NCEP October 5, 2006) SST departures in the Niño regions all greater than +0.5 Oceanic and atmospheric anomalies are consistent with the early stages of El Niño

  4. ENSODIAGNOSTIC DISCUSSIONCLIMATE PREDICTION CENTER/NCEP October 6, 2005  Statistical and coupled model predictions indicate El Niño conditions for the remainder of 2006 and into the NH spring (SH fall) 2007.

  5. Tropical Moored Array GTS • All moorings on multi-sat • Increased duty cycle (8 16 hours/day)

  6. TAO STATUS

  7. Vandalism Buoys move and sensors fail. Fishing boats often found near buoys and fishing gear in moorings.

  8. TAO Enhancements • SSS on all TAO moorings in 2007 • Heat, fresh water and momentum flux at 4 equatorial TAO sites (165ºE, 170ºW, 140ºW, 110ºW) • Support OceanSITES program

  9. TAO Transition • TAO Data Processing and Distribution at NDBC since Oct 2005 • Parallel Testing completed in Sep 2006 • NDBC assumes responsibility for field operations in Jan 2007 • Prototype “refreshed” moorings deployed in spring 2007 • PMEL responsible for preparation and maintenance of ATLAS instrumentation

  10. PIRATA STATUS

  11. PIRATA Enhancements • SW Extension – Brazil/US. 2005 • Heat, momentum and fresh water flux measurements on 3 moorings - 2006 • NE Extension - AOML/PMEL added 2 moorings in 2006. Additional 2 moorings in 2007. • SE Extension – 2006. 1 year only. South Africa (U. Capetown). France and US.

  12. 2006 PIRATA Enhancements • NE Extension to improve understanding and prediction of tropical Atlantic variability • Region of Atlantic cyclone development 11.5ºN 23ºW HELENE

  13. 2006 PIRATA Enhancements 15ºN 38ºW HELENE

  14. PIRATA Issues • PIRATA Review: • Should PIRATA continue? • Restructure responsibilities? • Ship requirements • Vandalism Ron Brown, May-June 2006 • K. Armah and colleagues. • University of Ghana

  15. Indian Ocean Moored Buoy Array

  16. Indian Ocean Status • 2000/2001 JAMSTEC deployed 2 TRITON and 1 subsurface ADCP and has maintained sites. • 2004 PMEL/NIO/NCAOR deployed 4 ATLAS and 1 subsurface ADCP from Sagar Kanya • 2006 PMEL/NIO/NCAOR deployed 5 ATLAS and 1 subsurface ADCP from Sagar Kanya • 2006 PMEL/BPPT to deploy 2 ATLAS from Baruna Jaya I • 2006 JAMSTEC MISMO Experiment • 2007 PMEL/IRD/IFREMER to deploy 1 ATLAS (Flux) and 1 subsurface ADCP from Suroit for CIRENE • 2007 PMEL/? (BPPT?, FIO?) proposed subsurface ADCP

  17. Indian Ocean Data Oct 2004 – Oct 2005 22 month long ADCP raw data record reveals seasonal and intraseasonal near surface current variability Oct 2005 – Sep 2006

  18. Indian Ocean Issues • Vandalism is a serious problem • 3 of surface moorings not recovered • New/modified mooring design? • 22 month deployments are well beyond mooring design lifetime and contribute to lower data quality and quantity • Adequate and regular ship time is necessary to build and maintain the array
