They also have a wide range of closed to open morphologies and several have been suitable to develop from black-lipped pearl oysters a substantial pearl farming activity in the past 30 years, representing nowadays the 2nd source of income for French Polynesia. Considering here only the component of lagoon renewal that is driven by waves, we investigate for 74 atolls different lagoon renewal metrics using 20 years of wave model data at 0.05 degrees spatial resolution. Wavelet spectral analyses highlight that atolls, even in close vicinity, can be exposed to different and characteristic periodicities in wave-driven flows and water renewal. These characteristics are discussed in relation to pearl farming atolls, including atolls known to be efficient oyster spat producers, a critical activity for pearl farming sustainability. specialized Tuamotu Pearl farming WaveWatch III Hoa Residence time Wavelet transform PACIFIQUE POLYNESIE FRANCAISE TUAMOTOU GAMBIER SOCIETE ILES 040 064 032 179 113748 [17 p.] 2022 0025-326X https://www.documentation.ird.fr/hor/fdi:010085265 10.1016/j.marpolbul.2022.113748 0025-326X [F B010085265] https://www.documentation.ird.fr/hor/fdi:010085265 https://www.documentation.ird.fr/intranet/publi/2022-09/010085265.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2022-09-02 2025-02-24 fdi:010085265 fre
