Data for: Long-term shoreline monitoring on a coral reef island (Moorea, French Polynesia)

Quantitative evolution of coastline categorization of Moorea Island from 1977 to 2018. At Moorea, the coastline is characterized by seven main habitat categories (Aubanel et al. 1999): 1/ Rocks and broken stones in their original positions (the rocks, either basaltic or carbonate, are over 50 cm in diameter and broken stones are 5-50 cm in size), 2/ White sand beach (at least 95% of which comprises coral sediments under 1 cm in size and the intertidal zone is not encumbered with vegetation), 3/ Black sand beach (same as white sand but with sediments of basaltic nature), 4/ Muddy areas or herbaceous zones, possibly with mangroves, 5/ Coarse mud-and-sand and detrital substrate with high vegetation area where Cocos nucifera, Hibiscus tiliaceus, Casuarina equisetifolia and Guettarda speciosa grow, 6/ Conglomerate and beach-rock and 7/ Anthropogenic changes (through walls, rocks and/or embankments).本数据集记录了1977年至2018年莫雷阿岛海岸线分类的定量演化情况。莫雷阿岛的海岸线可划分为7类主要生境（Aubanel等，1999）：1. 原位岩块与碎石（其中玄武岩或碳酸盐岩质岩块直径大于50cm，碎石粒径介于5~50cm之间）；2. 白沙滩（沉积物中95%以上为粒径小于1cm的珊瑚碎屑，且潮间带无植被覆盖）；3. 黑沙滩（与白沙滩特征一致，但沉积物为玄武岩质）；4. 泥质区域或草本植被带，可伴生红树林；5. 粗泥砂与碎屑基质生境，植被覆盖率较高，生长有椰子树（Cocos nucifera）、黄槿（Hibiscus tiliaceus）、木麻黄（Casuarina equisetifolia）及阔瓣茜草（Guettarda speciosa）；6. 砾岩与海滩岩；7. 人工改造区域（包括护墙、堆砌岩块及堤岸工程）。
