MCR LTER: Coral Reef: Ocean Currents and Biogeochemistry: salinity, temperature and current at CTD and ADCP mooring FOR05 from 2005 ongoing

Moored and bottom mounted instrumentation (ADCP, CTD, thermistors, wave-tide meters) sampled year-round
on the reef of Moorea Island, French Polynesia at site FOR05. Sampling began in 2005. All data have been
interpolated onto a 20 min grid. ADCP data are orgainized into 1-meter bins, measured as height from the
bottom, to a maximum of 20 bins. All bins may not be filled, and although post processing attempted to exclude
data from bins 'above the surface', users need to exercise caution with the near surface bins. CTD parameters
include Pressure, Temperature, Conductivity, Salinity and Density. The two moored CTD packages are located
approximately 5 and 14 meters above the bottom, and there are up to 5 additional temperature thermistors
spaced vertically along the mooring line. Note that the upper CTD was terminated in July 2020, bottom CTD was
terminated in October 2021, and temperature thermistor data was terminated in January 2020.
There are 2 bottom mounted thermistors in the vicinity of the mooring at 10 and 20 meter depth.
A bottom mounted wave-tide meter provides a measure of significant wave height
and dominant wave period at a 2 hour sampling interval. Tide related data may be calculated from bottom-mounted
pressure sensor data. 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 2005-2022). This work represents a
contribution of the Moorea Coral Reef (MCR) LTER Site.

本数据集涵盖布设于法属波利尼西亚莫雷阿岛（Moorea Island）FOR05站位珊瑚礁海域的系泊式与海底安装观测仪器的全年连续采样数据，观测仪器包括声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，简称ADCP）、温盐深剖面仪（Conductivity, Temperature, Depth，简称CTD）、热敏电阻及波潮仪。采样工作始于2005年，所有数据均已插值至20分钟的时间网格。ADCP数据按距底高度以1米为间隔分层，最大分层数为20层；并非所有分层均包含有效数据，尽管后期处理尝试剔除"海面以上"分层的数据，但使用者仍需对近海面分层的数据保持谨慎。CTD测量参数包括压力、温度、电导率、盐度与密度，两套系泊式CTD分别布设于距底约5米和14米处，另有最多5支温度热敏电阻沿系泊缆垂直布设。需注意：上层CTD于2020年7月停止运行，底层CTD于2021年10月停止运行，温度热敏电阻的数据采集则于2020年1月终止。站位附近的海底还布设有2支热敏电阻，布设深度分别为10米和20米。海底安装的波潮仪以2小时的采样间隔记录有效波高与主波周期，潮汐相关数据可通过海底压力传感器数据计算得到。本数据集基于美国国家科学基金会（U.S. National Science Foundation）编号为OCE 16-37396（及此前资助项目）的资助项目，以及戈登和贝蒂·摩尔基金会（Gordon and Betty Moore Foundation）的慷慨捐赠完成。本研究依据法属波利尼西亚政府（Délégation à la Recherche）及法国驻法属波利尼西亚高级专员公署（Haut-commissariat de la République en Polynésie Francaise，简称DTRT）签发的许可开展（接待协议2005-2022）。本数据集为莫雷阿珊瑚礁长期生态研究站（Moorea Coral Reef LTER Site，简称MCR LTER）的研究成果。
