These factors are partly controlled by the wave conditions that impact the lagoon circulation. To characterize the wave conditions around 83 SCP atolls including those hosting pearl farming activities, we used 18 years of WaveWatchlll simulation with a grid refined from 50 to 5 km resolution. Three regional wave regimes are statistically identified: two associated with long distant swells originating from mid-latitude storms, and one with local trade winds. All regimes occur with a relatively high frequency (22-44%), but with a marked seasonality. Wave conditions are also strongly modified locally during their propagation between the archipelagoes. Western and southern isolated atolls generally have a single regime all around their rims. In contrast, central Tuamotu atolls experience different regimes depending on their levels of protection. These results help understanding atoll hydrodynamics, which has implications for their management. specialized Wave regimes Atoll hydrodynamics Atoll rim Tuamotu Cook Islands WaveWatchlll POLYNESIE FRANCAISE GAMBIER COOK 032 020 036 162 111751 [11 ] 2021 0025-326X https://www.documentation.ird.fr/hor/fdi:010081040 10.1016/j.marpolbul.2020.111751 0025-326X [F B010081040] https://www.documentation.ird.fr/hor/fdi:010081040 https://www.documentation.ird.fr/intranet/publi/2021/03/010081040.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2021-04-01 2025-02-24 fdi:010081040 fre
