Description:
Characteristics, elevations and ages of 165 samples from various mid-late Holocene features, such as in situ Porites microatolls, in situ reef flats, conglomerates and reworked reef blocks, collected from twelve islands in French Polynesia. This table complements the database on which the mid-late Holocene sea-level curve has been initially reconstructed (Hallmann et al., 2018). Δ modern-fossil represents the difference in elevation between modern and Holocene microatolls at the same study site and in a similar environment (maximum vertical error is of ± 2 cm). NGPF = altimetric reference of French Polynesia. The elevations have been corrected for subsidence based on rates of 0.14 mm/yr for Moorea, 0.05 mm/yr for Bora Bora and Tahaa as well as 0.03 mm/yr for Maupiti, the Gambier Islands and Raivavae. Error values for ages and elevations are 2-sigma. Uncertainties for measured elevations related to NGPF are ± 14 cm for samples from Bora Bora, Maupiti, Raivavae, Tikehau and the Gambier Islands; ± 22 cm for samples from Fakarava, Hao, Makemo, Manihi, Moorea, Rangiroa and Tahaa. Uncertainties for estimated elevations are ± 10 cm for Δ modern-fossil and ± 22 cm for NGPF elevations.
