Lagoon hydrodynamics of pearl farming atolls in French Polynesia : the case of Raroia Atoll (Tuamotu Archipelago)

Raroia Atoll has been instrumented over a period of 10 months (from May 2018 to late March 2019) separated into 3 Legs and 1 extra leg (namely "shortleg"). Physical process such as water level, wave climate, currents ciruclation, exchanges between ocean and lagoon by passes and "hoa" and water column stratification have been measured to characterized the hydrodynamic functioning of this semi-open pearl farming atoll. Numerous moorings have been deployed into lagoon, hoa, passes and external reef slope stations with common autonomous oceanographic instruments measuring at high sampling frequency. 

Sampling strategy available on Sextant - Marine Geographic Information System.
