Figure 1. KESS Observational Plan Next May 2004, this array is going to be deployed. Currently there are no air-sea flux measurements in this plan.

Figure 2. KESS science objectives KESS (Kuroshio Extension System Study) goals are to understand the dynamics and thermodynamics between the Kuroshio Extension and the Recirculation Gyre.

This is where the ACTION is. The need for air-sea flux measurements goes far beyond the needs of this experiment. However, the KESS experiment can be used as a way to begin long-term monitoring of the air-sea interaction in the Kuroshio Extension Region, a region that impacts the entire Pacific basin and beyond. To piggy back the longterm monitoring onto the KESS experiment, air-sea flux buoys would need to be deployed SOON -- on Nelson Hogg's mooring cruise in May 2004.
Figure 5. Simple EPIC-type moorings... The strategy would be to make the moorings simple. They must have extremely low drag (slack-line) and heavy anchor. If the load becomes intolerable, the mooring would either break away from its anchor, or sink. In any case, we will have learned much about the climate system, and about moorings in high current regimes. Refurbished EPIC inventory can be used to make these moorings very economical.
