Apataki Atoll has been instrumented over a period of 3 months (from April 2022 to late July 2022) separated into 2 Legs. Physical process such as water level, currents ciruclation, water exchanges into passes and "hoa" and water column stratification have been measured to characterized the hydrodynamic functioning of this semi-opened pearl farming atoll. Numerous moorings have been deployed into lagoon, passes, hoa and external reef slope stations with common autonomous oceanographic instruments measuring at high sampling frequency. During the sampling period, one major meteorological event occurred, a distant mega swell hit the South-West Islands of French Polynesia including Apataki on 14th July and has significantly impacted its hydrodynamic.

The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.

Takaroa Atoll has been instrumented for a short period of 3 months (from July 2022 to October 2022) in order to get additionnal data into Takaroa passage (Teauoae Pass). One ADCP has been deployed to measure current direction and speed over the water column to evaluate the water exchanges between the lagoon and the ocean of this semi-open pearl farming atoll.

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.)-[https://sextant.ifremer.fr/Donnees/Catalogue#/metadata/b88e3214-17fe-45d1-9b21-2215564ce092] More informations on (ANR MANA project)-[https://www.coreus.ird.fr/index.php/home-en/home/research/portfolio/ongoing-projects/projet-mana].   Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI.
