CADHYAK surveys : Field observations of hydrodynamics functioning of Koumac Lagoon (New Caledonia - North Province)
Koumac lagoon has been instrumented over a period of 6 months (from December 2019 to May 2020) in order to characterized its hydrodynamics functioning. This lagoon is surrounding by mining activities that may affect and damage its ecosystem. Nineteen sensors have been deployed on moorings to measure and quantify water circulation and exchanges between land, lagoon and ocean (current, temperature, salinity and pressure). CTD profiles have also been performed to observe spatial extent and stratification of water bodies. During the sampling period, two major meteorological events occurred, UESI cyclone (11th February 2020) and GRETEL tropical depression (15th march 2020), which have significantly impacted hydrodynamics. Sampling strategy available on Sextant.- Marine Geographic Information System. More informations on PRESENCE project.
