Summary of measurements

-38 STD hauls from 0 to 1,000 m using rosette to take 12 samples per station to be analysed: salinity, chlorophyll, nitrates and nitrites, phosphates.
-38 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.
-Mooring of PMEL thermistor chains at 2°S and 2°N.
-38 net hauls from 0 to 500 m and 38 net hauls from 0 to 200 m to estimate the biomasses of mesozooplankton and macrozooplankton.
-Routine measurements (every 3 hours).
