Summary of measurements

-35 CTD stations at 1,000 m using rosette to take 12 samples per station to be analysed: salinity, chlorophyll, dissolved oxygen and nutrients.
-35 current profiles from 0 to 600 m.
-Surface samples taken (for analyses) every 3 hours and XBT casts (30) every 6 hours on return trip (between Kwajalein and 20°S).
-Recovery of current meter moorings (at 2°N: Surtropac 85-02 mooring and at the Equator: the University of Washington's mooring).
-Mooring of thermistor chains at 2°N and 2°S.
-35 vertical net hauls from 0 to 500 m for biomass estimation and mesozooplankton determination.
-35 net hauls from 0 to 200 m to study macrozooplankton.
-Routine measurements (every 3 hours).
