1. Updates on PP Observational Programs Wenju Cai

3. An unprecedented opportunity South Pacific Circulation and Climate Experiment (SPICE) Northwest Pacific Ocean Circulation and Climate Experiment (NPOCE) Origin of the Kuroshio and Mindanao Current (OKMC) Tropical Western Pacific Climate Experiment (GAIA)

4. An overview of programme

7. GAIA Monitoring

8. Coordination is an issue An NPOCE implementation workshop is to be held in China, January 17-18 2010. Participants include: Arnold Gordon, Steve Riser, William Kessler, Jae-Hak Lee, Bo Qiu Yukio Masumoto, Dwi Susanto, Alex Ganachaud, Ed Harrison …

9. SPICE Progress

10. SPICE Experiments

11. Progress of SPICE Started in 2004, field experiments have reached their intensive phase, which is expected to continue until 2012 and beyond for specific monitoring. A field experiment was designed to monitor the entrance of the large, easterly South Equatorial Currents into the Coral Sea, along with its outflows toward the equator and to the Southern Ocean. Using repeated XBTs and Argo profiles, an experimental monitoring system is ongoing. Near the Australian shelf, the expanding IMOS mooring network measures the coastal boundary current flows. This is complemented with glider surveys across the boundary currents (currently starting). Surface drifters are released repeatedly across the East Australian Current to calibrate the ocean simulations and forecast from the Bluelink operational system (BMRC).

12. Continued In the Solomon Sea, intensive glider monitoring is ongoing. A major cruise has been funded (2010-2011). During this cruise, mooring deployments are planned in key places of the Solomon Sea to monitor the transports toward the equator.

13. SECARGO: SEC entrance monitoring

14. Glider missions in the Solomon Sea (SIO/PMEL/IRD) The striking feature shown in the right panel is that at the start of 2008, equatorward transport in the Solomon Sea nearly disappeared, then was restored by mid-2008. This was likely the result of the La Nina winds producing southward anomalies of the boundary currentThe striking feature shown in the right panel is that at the start of 2008, equatorward transport in the Solomon Sea nearly disappeared, then was restored by mid-2008.

15. SPICE Experiments

16. SPICE data Glider data are live on the net Other data are described in SPICE website

22. We hope to duplicate the practice in other projects
