    As part of the PACS/EPIC program, the TAO 95W line has been enhanced with additional sensors and moorings to monitor heat, moisture, and momentum fluxes and upper ocean temperature, salinity, and velocity, from the stratus deck region at 8S, 95W through the cold tongue to 12N, 95W, north of the ITCZ.

    Enhancements began in Fall 1999 and are scheduled to span a total of 3-4 years.

    These measurements show complex meridional structure and temporal variability.

    TAO flux moorings can act as flux reference sites. Cross-reference studies with other flux moorings (TAO, IMET, TRITON) are currently underway.
