Objective	Studying the physical and biogeochemical conditions of the eastern edge of the warm waters in the west equatorial Pacific Ocean and continuing studies on long term variability on the leg along 165°E. Comments on the cruise's progression: Difficulties encountered with the L-ADCPs' connection cable, with pCO2 loggings and with one of the beams of the S-ADCP (post-processing modified).

Summary of measurements

-90 stations made.
-Work at stations included:
-CTD-02 and L-ADCP profiles and samples taken with a 12 bottle rosette to measure chemical parameters. -Parameters measured: - salinity, temperature, dissolved oxygen, ammonium, nitrate, phosphate and chlorophyll A.
Continuous recordings during trip:
-S-ADCP current (0-250m).
-Temperature and salinity on TSG.
-Partial CO2 pressure at surface and surface meteorological conditions.
Others:
-Maintenance of TAO network buoy at 2°N-165°E, deployment of drifting surface floats for SVP network, 20 PROVOR float of the ARGO network and 2 SURFACTS buoys (PI: Jacqueline Boutin from LODYC/LOCEAN).
