National Coral Reef Monitoring Program: Water Temperature Data from Subsurface Temperature Recorders (STRs) deployed at coral reef sites in the Pacific Remote Island Areas from 2012-03-04 to 2015-11-12 (NCEI Accession 0162217)

Water temperature data are collected using subsurface temperature recorders (STRs) that aid in the monitoring of seawater temperature variability at permanent coral reef sites in the Hawaiian and Mariana Archipelagos, American Samoa, and the Pacific Remote Island Areas as part of the NOAA National Coral Reef Monitoring Program (NCRMP). High-accuracy temperature loggers made by SeaBird Electronics (SBE) are deployed on the reef for a period of 3 years at depths ranging from 0 to 30 meters along depth transects at Ocean and Climate Change monitoring survey sites. When a STR is recovered, typically another STR is deployed in the same location. Raw data with an original sample interval ranging from 1 to 20 minutes are averaged hourly, and gaps of longer than one hour in the time-series, due to instrument failure or battery death, are padded with null values. Temperate data are archived by region and year recovered. For analysis purposes, temperature sensor deployments are grouped by site, and temperature data from successive deployments at each site are concatenated.

The temperature data provided in this data set were collected from STRs deployed at existing, long-term monitoring sites during NOAA Pacific Islands Fisheries Science Center (PIFSC), Coral Reef Ecosystem Program (CREP) led NCRMP missions.

本数据集的水温数据由水下温度记录仪（subsurface temperature recorders, STRs）采集，作为美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）国家珊瑚礁监测计划（National Coral Reef Monitoring Program, NCRMP）的组成部分，用于监测夏威夷群岛、马里亚纳群岛、美属萨摩亚及太平洋偏远岛礁区域的永久性珊瑚礁站点的海水温度变化。由SeaBird Electronics（SBE）制造的高精度温度记录仪被部署于海洋与气候变化监测调查站点的深度断面上，部署深度范围为0至30米，单次部署时长为3年。当一台水下温度记录仪被回收后，通常会在同一位置部署新的同类设备。原始采样间隔为1至20分钟的原始数据会被按小时进行平均处理；因仪器故障或电池耗尽导致的时间序列中超过1小时的数据间隙，将以空值填充。水温数据会按区域及回收年份进行归档。为开展分析工作，会按站点对温度传感器的部署任务进行分组，并将每个站点历次部署所采集的温度数据进行拼接。本数据集所提供的水温数据，采集自美国国家海洋和大气管理局太平洋岛屿渔业科学中心（Pacific Islands Fisheries Science Center, PIFSC）珊瑚礁生态系统项目（Coral Reef Ecosystem Program, CREP）主导的国家珊瑚礁监测计划任务期间，部署于现有长期监测站点的水下温度记录仪。
