资源简介:

Characteristics, elevations and ages of 72 in situ Porites microatolls collected from five islands in French Polynesia. Delta 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 are not corrected for uplift or subsidence. Error values for ages and elevations are 2-sigma. Uncertainties for measured elevations related to NGPF are ± 14 cm for microatolls from Bora Bora, Maupiti and Tikehau; ± 22 cm for samples from Rangiroa and Tahaa. Uncertainties for estimated elevations are ± 10 cm for Delta modern-fossil and ± 22 cm for NGPF elevations. Samples BOB-52/-224 and TIK-86/-87 are from the same microatoll, respectively.

本数据集包含采自法属波利尼西亚5座岛屿的72个原位(in situ)滨珊瑚(Porites)微型环礁的特征、高程与年代数据。现代-化石差值(Delta modern-fossil)指同一研究区域、相似环境下现代微型环礁与全新世(Holocene)微型环礁的高程差,其最大垂直误差为±2厘米。NGPF即法属波利尼西亚高程基准面(altimetric reference)。本数据集的高程数据未针对隆升或沉降进行校正。年代与高程的误差值均为2σ(2-sigma)置信区间。基于NGPF基准的实测高程不确定度:波拉波拉岛、莫皮蒂岛与蒂克豪环礁的微型环礁样品为±14厘米,朗伊罗阿环礁与塔哈岛的样品为±22厘米。估算高程的不确定度:现代-化石差值为±10厘米,NGPF基准高程为±22厘米。样品BOB-52/-224与TIK-86/-87分别取自同一微型环礁。
