Hydrographic and velocity data during Leg 1 of the R/V Hespérides MOC2 cruise, 7-18 April 2010, western equatorial Atlantic

Résumé fourni par la source

This dataset consists of 47 CTD and LADCPs casts from the sea surface down to 5000 m. These hydrographic casts were done during the first leg of the MOC2-Equatorial oceanographic cruise, which took place in the western equatorial Atlantic (5°S-5°N; 46°W-30°W] between 7 and 18 April 2010, onboard the R/V Hespérides. Temperature and conductivity were obtained with a SeaBird 911-Plus multi-probe system mounted on a 24 Niskin-bottle rosette that collected water samples at standard depths, which were used to calibrate the conductivity data. Duplicate temperature and conductivity sensors were used as a quality control measure. The LADCPs were RDI 300 kHz Workhorse Monitor instruments used in synchronized master-slave mode. The system was set to a ping-rate of 1 ping/s and a bin length of 10 m, and the data was processed using the IFM-GEOMAR LADCP software, Version 10.8. The LADCPs velocity data were de-tided using the TPXO.3 global model of ocean tides. The netcdf file MOC2_leg1.nc contains data interpolated linearly every 1 m from surface to 1500 m depth.
