Annual cycle of the Atlantic North Equatorial countercurrent IRD
Richardson, P.L.; Arnault, Sabine; Garzoli, S.; Bruce, J.G..
An analysis of numerous meridional XBT sections near 28°W reveals that the geostrophic North Equatorial Countercurrent (NECC) continues to flow eastward throughout the year, fatest in fall and slowest in spring. Drifting buoys and historical ship drifts show that the near-surface Countercurrent reverses each spring even when systematic errors due to windage are taken into account. The seasonally fluctuating winds drive an Ekman surface current that is eastward in fall, adding to the geostrophic current, and westward in spring, countering and overwheling the geostrophic current. The reversal of the countercurrent in spring occurs in the near-surface layer and is driven by the Northeast trades. Thus the near-surface velocity in the countercurrent is...

Atlas des températures et des courants géostrophiques de 1979 à 1985 déduits des mesures XBT le long des rails de navigation du Pacifique tropical IRD
Picaut, Joël; Tournier, R.; Fabre, V..
Dans le Pacifique tropical, la concentration de données du réseau XBT (expendable bathythermograph) ORSTOM-SIO (Scripps Institutio of Oceanography) autour de trois rails de navigation a permis de construire des champs de températures et de courants géostrophiques. Afin d'obtenir des champs de températures les plus précis possible, le fichier original ORSTOM-SIO a été tout d'abord triplé par la récupération d'un maximum de données XBT et de quelques données hydrologiques et de sondes CTD (conductivité, température, profondeur) auprès de différents services océanographiques. Les champs de températures à trois dimensions (latitude, profondeur, temps) ont été obtenu en regroupant, indépendamment de la longitude, les données de profils thermiques autour de...

Comparaisons des systèmes productifs de l'Atlantique tropical est : dômes thermiques, upwellings côtiers et upwelling équatorial IRD
Voituriez, B.; Herbland, Alain.
All the high-productive systems of the Eastern tropical Atlantic between 20°N and 15°S - coastal upwelling, equatorial upwelling, and thermal domes-are partly controlled by the subsuperficial equatorial countercurrent system, which feeds all of them with Southern Atlantic Central Water. However, the enrichment processes in the systems are quite different, and thus the structures differ from one another. Two types have to be considered : 1) the quasi geostrophic ones which are two-layered systems belonging to the "typical tropical situations", where the primary production is controlled by the depth of the nitraciline; 2) the systems including coastal upwelling and equatorial divergence in summer, where the warm nitrate-depleted mixed layer is absent....

Geosat-derived sea level and surface current anomalies in the Equatorial Pacific during the 1986-1989 El Nino and La Nina IRD
Delcroix, Thierry; Boulanger, Jean-Philippe; Masia, François; Menkès, Christophe.
Equatorial wave dynamics are essential in most oceanic models for reproducing aspects of the El Nino-Southern Oscillation (ENSO) phenomenon. In this paper, observational evidence of first baroclinic equatorial Kelvin and first symetric meridional Rossby waves is found in Geosat-derived sea level anomalies (SLA) and surface zonal current anomalies (ZCA) in the Equatorial Pacific ocean during the 1986-1987 El Nino and the ensuing 1988-1989 La Nina. This was made possible after extensive quality control and specific processing of the recently improved Geosat geophysical data records pertaining to the 17-day Exact Repeat Mission. In particular, the processing was made so that the Geosat-derived ZCA best fit near-surface zonal currents from three Equatorial...
