MAUPITI HOE - wave friction

maupiti ("the stuck twins'') is a diamond-shaped island located in the western part of the society archipelago in french polynesia. the present study focuses on the data recovered over a single cross-barrier transect located in the south-west barrier during the maupiti hoe field campaign, from 5 to 18 july 2018. the studied area is representative of the reef structure observed along the 4km-long southwestern barrier reef, showing an alongshore-uniform structure exposed to swell approaching with weak incident angles, a healthy reef colony. in the cross-barrier direction, the reef displays a clear partitioning of bottom roughness that ranges from low-crested compact structures at the reef crest to higher and sparser coral bommies on the backreef. the experimental setup was specifically designed to analyse and differentiate the dynamics over three roughness-contrasting sections found over the barrier reef.

莫阿皮蒂岛（俗称‘被困的双胞胎’）位于法属波利尼西亚社会群岛的西部，呈钻石形状。本研究聚焦于在莫阿皮蒂岛 Hoe 野外考察期间，于西南部屏障岛上的单一横断面所恢复的数据，考察时间自2018年7月5日至7月18日。研究区域代表了沿4公里长的西南部屏障礁观察到的珊瑚礁结构，该区域呈现沿岸均匀结构，暴露于以弱入射角接近的涌浪，并呈现出健康的珊瑚礁群落。在横跨屏障的方向上，珊瑚礁展现出底部粗糙度的明显分区，从礁顶的矮丘状紧密结构到背礁上更高且分布稀疏的珊瑚礁石。实验装置被特别设计，以分析和区分在屏障礁上发现的三个粗糙度对比显著的区域所表现出的动态变化。
