Objective	Observation of hydrological and currentometric structures along the 156E meridian on legs repeated 18 times between 5N and 5S in the Coral Sea between 20S-New Caledonia and 6S-Bougainville strait, and study of these structures' spatial-temporal variability, in relation to atmospheric forcing and the ENSO (El Nino and Southern Oscillation) phenomenon.
