MCR LTER: Coral Reef: Water Column: Nearshore Water Profiles, CTD, Primary Production, and Chemistry ongoing since 2005

This data package contains water chemistry measurements taken 2 to 4 times per year at 6 stations on the north shore of Moorea, French Polynesia: Forereef, Lagoon, Fringing Reef, Cooks Bay, Cooks Bay Stream Mouth, and Offshore (5 km due north). Measurements include standard CTD parameters, nutrients, chlorophyll, phaeopigments, particulate organic carbon and nitrogen, dissolved organic carbon, dissolved inorganic carbon, total alkalinity, water column primary production, and abundance of bacteria. Sampling began in August, 2005. All water samples were collected with Niskin Bottles. CTD data were collected with a SBE19-Plus Seacat Profiler outfitted with WetLabs FLNTURT-221 Flurometer/turbidity sensors. CTD and bottle samples were taken on separate casts at each station. Two additional stations on the Moorea east shore were sampled in August 2005 only: LTER 3 Forereef Water Column, LTER 3 Backreef Water Column. This material is based upon work supported by the U.S. National Science Foundation under
Grant No. OCE 16-37396 (and earlier awards) as well as a generous gift from the Gordon and
Betty Moore Foundation. Research was completed under permits issued by the French Polynesian
Government (Délégation à la Recherche) and the Haut-commissariat de la République en
Polynésie Francaise (DTRT) (Protocole d'Accueil 2005-2018). This work represents a
contribution of the Moorea Coral Reef (MCR) LTER Site.

本数据包包含法属波利尼西亚莫雷阿岛北岸6个站位每年2至4次采样获取的水体化学测量数据，站位分别为：岸礁前区（Forereef）、潟湖（Lagoon）、岸礁边缘区（Fringing Reef）、库克湾（Cooks Bay）、库克湾河口（Cooks Bay Stream Mouth）以及远海海域（正北方向5公里处，Offshore）。测量指标涵盖标准CTD（Conductivity-Temperature-Depth，电导率-温度-深度仪）参数、营养盐、叶绿素、脱镁叶绿素、颗粒有机碳与氮、溶解有机碳、溶解无机碳、总碱度、水柱初级生产力以及细菌丰度。采样工作始于2005年8月，所有水样均采用尼斯金采水器（Niskin Bottles）采集。CTD数据由搭载WetLabs FLNTURT-221荧光计/浊度传感器的SBE19-Plus Seacat剖面仪获取，每个站位的CTD测量与水样采集分别通过独立的下放作业完成。仅在2005年8月对莫雷阿岛东岸的2个额外站位开展了采样，站位分别为LTER 3岸礁前水柱（LTER 3 Forereef Water Column）与LTER 3背礁水柱（LTER 3 Backreef Water Column）。本研究工作依托美国国家科学基金会（U.S. National Science Foundation）编号为OCE 16-37396的项目资助（及此前相关资助）以及戈登与贝蒂·摩尔基金会（Gordon and Betty Moore Foundation）的慷慨捐赠完成。研究实施获得了法属波利尼西亚政府（Délégation à la Recherche）与法兰西共和国驻法属波利尼西亚高级专员公署（Haut-commissariat de la République en Polynésie Francaise, DTRT）签发的许可（2005-2018年接待协议，Protocole d'Accueil 2005-2018）。本数据集为莫雷阿珊瑚礁（Moorea Coral Reef, MCR）长期生态研究（Long-Term Ecological Research, LTER）站点的研究贡献成果之一。
