REMMOA-I Aerial surveys for marine megafauna in French Polynesia, 2012

The aim of the REMMOA surveys is to establish an inventory of the spatial distribution and monitor the relative abundance of marine mammals, seabirds and other marine megafauna (such as sea turtles and large fish) in the French overseas territories and adjacent waters. Surveys are typically conducted over large marine areas, including offshore and coastal regions, using a standardised protocol (Doremus et al. 2020* This dataset represents the first implementation of REMMOA in French Polynesia in 2011. The transects were flown using twin-engine, high-wing aircraft at an average speed of 90 knots and an altitude of 600 feet. The on-board team consisted of three or four people who took turns manning the stations: two trained observers who looked with the naked eye through bubble windows (allowing the observer to look under the aircraft), and a navigator responsible for collecting the data using VOR software. The data were then validated and entered into the Pelagis Observatory's Observation at Sea database, from which they were extracted for this repository. * https://www.observatoire-pelagis.cnrs.fr/wp-content/uploads/2021/08/GuideMethodoAerien2020.pdf

REMMOA调查的核心目标为，建立法国海外领地及其邻近海域内海洋哺乳动物、海鸟及其他海洋巨型生物（marine megafauna，涵盖海龟与大型鱼类）的空间分布清单，并监测其相对种群丰度。调查通常采用标准化作业规程，在包括远海与近岸区域的大片海域开展（Doremus等，2020）*。本数据集为2011年REMMOA调查在法属波利尼西亚的首次实施成果。本次调查使用双发高翼飞机执行样线飞行，平均航速为90节，飞行高度为600英尺。机载作业团队由3至4名人员组成，轮流值守各岗位：2名经专业培训的观察员通过气泡舷窗以裸眼开展观测，该舷窗可使观察员视角覆盖机腹下方区域；另有1名导航员负责使用VOR软件收集观测数据。后续所有数据均经过校验验证，并录入佩拉吉斯天文台（Pelagis Observatory）的海上观测数据库，本数据集即从该数据库中提取所得。* https://www.observatoire-pelagis.cnrs.fr/wp-content/uploads/2021/08/GuideMethodoAerien2020.pdf
