A simple and rapid device for measuring planktonic primary production by in situ sampling, and 14C injection and incubation IRD
Dandonneau, Yves; Le Bouteiller, Aubert.
A system (LET GO) is described that enables measurements of primary production at sea after #in situ$ incubation, with 14C being injected at depth immediately after enclosure of the sample. Each incubation cell, about 200 ml, is made of two transparent plexiglass cups facing each other. Mechanical energy to operate the system is provided by the tension of the nylon line between the drifting buoy, which holds the experimental equipment, and a weight at the bottom : when the line is strained, the two cups enclose the water sample, and the 14C is delivered by a syringe. Absence of metallic or rubber parts ensures that toxicity effects are minimized and that reliable results can be expected. Furthermore, #in situ$ incubations can start 1 or 2 min after arrival...

Abnormal bloom of phytoplankton around 10°N in the western Pacific during the 1982-83 ENSO IRD
Dandonneau, Yves.
The chlorophyll concentration at the surface of the tropical Pacific has been monitored through the 1982-83 ENSO, owing to the SURTROPAC ships of opportunity network. The event was characterized by a decrease in chlorophyll concentrations at the equator, where a belt of relatively rich water however persisted. The most striking anomaly was observed in the western Pacific between 5°N and 15°N. In this region, chlorophyll at the surface is generally less than O.O7 mg m-3, caused by a mixed layer exhausted in nutrients and by strong density gradient in the thermocline. From october 1982 to march 1983, higher concentrations up to 0.70 mg m-3 have been recorded by the network. This is consistent with the shallowing of the thermocline which characterizes all...

Displacements and transformations of nitrate-rich and nitrate-poor water masses in the tropical Pacific during the 1997 El Nino ArchiMer
Radenac, Marie-helene; Dandonneau, Yves; Blanke, Bruno.
A Lagrangian analysis was applied to the outputs of a coupled physical-biogeochemical model to describe the redistribution of nitrate-rich and nitrate-poor surface water masses in the tropical Pacific throughout the major 1997 El Nino. The same tool was used to analyze the causes of nitrate changes along trajectories and to investigate the consequences of the slow nitrate uptake in the high nutrient low chlorophyll (HNLC) region during the growth phase of the event. Three patterns were identified during the drift of water masses. The first mechanism is well known along the equator: oligotrophic waters from the western Pacific are advected eastward and retain their oligotrophic properties along their drift. The second concerns the persistent upwelling in...

La chlorophylle dans le Pacifique : un essai d'océanographie à partir de mesures à la surface de l'océan IRD
Dandonneau, Yves.
Des données de concentration en chlorophylle à la surface de l'Océan Pacifique, obtenues grâce à une technique spécialement mise au point, sur les lignes de navigation commerciale entre Nouméa et le Japon, l'Amérique du Nord et Panama, permettent de suivre l'évolution du Pacifique de 1979 à 1986. Les effets d'île, l'El Nino de 1982-83, les variations saisonnières autour de la Nouvelle Calédonie, et l'extension de la zone enrichie par l'upwelling dans le Pacifique font l'objet d'études particulières.
