Circulation patterns in a channel reef-lagoon system, Ouano lagoon, New Caledonia Sous, D. /Chevalier, Cristèle Devenon, J. L. /Blanchot, Jean /Pagano, Marc This paper reports on two three-months field experiments carried out in the Ouano lagoon, New Caledonia. This channel-type lagoon, exposed to meso-tides, south pacific swells and trade winds, has been monitored thanks to a network of currents profilers to understand the dynamics of the lagoon waters. Four typical circulation patterns have been identified, covering all together more than 90% of the survey period. These patterns are mainly driven by the waves and wind features. In particular, obliquely incident waves or strong winds blowing over a sufficient period are able to reverse the typical circulation pattern. The analysis of the vertical structure of the currents through passages shows the regular presence of a nearly linear vertical shear within the water column. 2017 text https://www.documentation.ird.fr/hor/fdi:010071045 fdi:010071045 Sous D., Chevalier Cristèle, Devenon J.
