La campagne FLUPAC du N.O. L'Atalante, qui s'est déroulée du 23 septembre au 29 octobre 1994, s'est placée dans le cadre du programme international JGOFS (JOINT GLOBAL OCEAN FLUX STUDY). Elle a comporté deux radiales et deux stations équatoriales de 6-7 jours. La première radiale, le long de 165°E, a parcouru la zone comprise entre 20°S et 6°N. La seconde s'est déroulée le long de l'équateur entre 167°E et 150°W. Les deux stations de longue durée ont eu lieu à O°-167°E et 0°-150°W. Elles ont été l'occasion d'études détaillées des flux impliqués dans le cycle du carbone de la couche superficielle (0-500 m). Le premier tome du recueil de données présente des résultats, sous forme de graphiques et de tableaux, des paramètres enregistrés en continu et de ceux...

Coupes verticales des structures océaniques physiques à 165°E observées au cours de dix campagnes SURTROPAC, 1984-1988 IRD
Eldin, Gérard.
In, 1984, the SURTROPAC group from the ORSTOM Center in Noumea has undertaken a series of trans-equatorial biannual cruises, along the 165°E meridian, from 20°S-10°N. These cruises are now part of the international TOGA program, and are scheduled until 1994. Half-way of this series, this report presents sections of temperature (T), salinity (S), potential density, zonal geostrophic currents (Ug), and zonal (u) and meridional (v) components of measured currents, for each of the 10 cruises already carried out. Some indications on data processing and contouring algorithms are given before. Two different types of hydrology probes and current profilers were used for measurements : for cruises § 1-5, a Bisset-Berman model 9040 STD probe, and a more accurate...

Des Açores à la Nouvelle-Calédonie : un demi-tour du monde de mesures avec un profileur acoustique à effet Doppler IRD
Eldin, Gérard.
Ce rapport présente les résultats des mesures au profileur de courant acoustique à effet Doppler (ADCP) effectuées au cours de la traversée Brest-Nouméa du navire océanographique LE NOROIT de décembre 1990 à mars 1991. Les données ont été recueillies durant le transit Atlantique des Açores à Panama, et pendant la campagne ALIZE 2 le long de l'équateur dans le Pacifique. Le principe de fonctionnement de l'ADCP est rappelé brièvement, et l'installation d'un modèle RDVM-150 fabriqué par RD Instruments sur LE NOROIT est décrite. Les méthodes d'acquisition et de traitement des données sont détaillés. Les résultats sont exposés sous forme de coupes verticales des composantes zonale et méridienne des courants, pour chaque partie de la traversée. (Résumé d'auteur)

Effects of westerly wind bursts upon the Western Equatorial Pacific ocean, february-april 1991 IRD
Delcroix, Thierry; Eldin, Gérard; McPhaden, M.J.; Morlière, Alain.
In February-April 1991, episodes of 2 to 8 m s-1 westerly winds of 3 to 11 days' duration occurred in the Western Pacific warm pool. Resulting modifications of the upper ocean in current and hydrology are quantified using data from an equatorial mooring at 165°E and from three cruises within 30 days of one another along 165°E. During westerly wind bursts (WWB) stronger tha m s-1, the upper 50 m becomes isothermal to within O.1°C and sea surface temperature (SST) drops by 0.3.-0.4°C between 5°S and 2.5°N. Conversely, STT starts warming and the upper 50 m restratifies in 4-5 days after the end of WWB. In contrasts to previous observations, salinity between 0 and 50 m appears almost unaffected by WWB; it freshens by 0.4 practical salinity unit in March within...

Equatorial Kelvin and Rossby waves evinced in the Pacific ocean through GEOSAT sea level and surface current anomalies IRD
Delcroix, Thierry; Picaut, Joël; Eldin, Gérard.
Equatorial Kelvin and Rossby waves are comprehensively demonstrated over most of the equatorial Pacific basin, through their signatures in sea level and zonal surface geostrophic current anomalies. This was made possible with altimeter data pertaining to the first year of the Geosat (Geodetic Satellite) 17-day exact repeat orbit (November 8, 1986, to November 8, 1987). To this end, along-track corrected Geosat sea level anomalies (SLAs), relative to the time period of interest, were first smoothed using nonlinear and linear filters. The original 17-day time step was then reduced by combining all ascending and descending tracks within 10° longitudinal bands. Finally, SLAs were gridded onto a regular grid, and low-pass filters were applied in latitude and...

Evolution of the Western Pacific ocean during the 1986-1987 El Nino IRD
Toole, J.; Delcroix, Thierry; Eldin, Gérard; Firing, E.; Francis, M.; Hénin, Christian; Jiang, S.; Mangum, L.; Millard, R.; Picaut, Joël; Pu, S.; Radenac, Marie-Hélène; Wang, Z.; Zou, E..
A series of 12 meridional transect along longitude 165°E in the Western Equatorial Pacific ocean were made between mid-1986 and mi-1988 : a time interval spanning an El Nino/Southern Oscillation (ENSO) event. Data collected on these cruises provide a detailed (albeit temporally sparse) view of the oceanic changes which occur in the Western Pacific during an ENSO event. The present work focuses on the evolution of the upper ocean thermohaline and zona velocity fields as revealed by high resolution hydrographic casts and direct near surface velocity measurements.

GEOSAT sea level anomalies in the Western equatorial Pacific during the 1986-87 El Nino, elucidated as equatorial Kelvin and Rossby waves IRD
Delcroix, Thierry; Eldin, Gérard; Picaut, Joël.
Thanks to the GEOSAT altimeter data set, information on sea level changes during the 1986-87 El Nino is presented. Special emphasis is placed on the warm pool area, with an evaluation, a detailed description and tentative explanation of the observed Sea Level Anomaly (SLA) changes. Near the 165°E longitude,the onset of the 1986-87 El Nino is characterized by a rapid development of a positive (> 14 cm) equatorial SLA in november-december 1986. This feature occurs in response to an eastward wind anomaly appearing between 140°E-170°W along the equator. The wind induces a downwelling equatorial Kelvin wave with phase speed of about 2.3 m.s.-1. Thereafter, equatorial SLA remains quite constant from january to april/may 1987. In june 1987, equatorial SLA...

Large-scale current and thermohaline structures along 156°E during the COARE intensive observation period IRD
Eldin, Gérard; Delcroix, Thierry; Hénin, Christian; Richards, K.; Penhoat, Yves du; Picaut, Joël; Rual, Pierre.
From December 1992 to February 1993, 18 meridional sections of temperature, salinity, and current were collected along 156°E, from 5°S to 5°N, during the Intensive Observation Period of the Coupled Ocean-Atmosphere Response Experiment. The average conditions were characteristic of the ongoing El Nino event, with a relatively shallow thermocline and fresh surface waters. Alternating westerly and easterly wind forcing was observed, and the warm surface layer (the "Warm forcing was observed, and the warm surface layer (The "Warm Pool") responded in a time scale of a few days by corresponding alternating flows; the Equatorial current system was less affected at depht. The upper-layer oceanic temperature variability involved several mechanisms, including...
