Oceanographic data collected from Lower Sand Island light (USCG day mark green 5) by Center for Coastal Margin Observation and Prediction (CMOP) and assembled by Northwest Association of Networked Ocean Observation Systems (NANOOS) in the Columbia River Estuary and North East Pacific Ocean from 199

NCEI Accession 0162181 contains navigational and physical data collected at Lower Sand Island light (USCG day mark green 5), a fixed station in the Columbia River estuary - Washington/Oregon. These sensors measure CONDUCTIVITY, DEPTH - OBSERVATION, HYDROSTATIC PRESSURE, LATITUDE, LONGITUDE, SALINITY and WATER TEMPERATURE at frequent intervals in the nearshore coastal ocean. The Center for Coastal Margin Observation & Prediction collected the data and provided the data to NANOOS, which assembles data from The Center for Coastal Margin Observation & Prediction and other sub-regional coastal and ocean observing systems of the Northwest Coastal United States, submitted the data to NCEI as part of the Integrated Ocean Observing System Data Assembly Centers (IOOS DACs) Data Stewardship Program. The data are made available in netCDF formatted files, which follow the Climate and Forecast metadata convention (CF) and the Attribute Convention for Data Discovery (ACDD). Each month, NCEI adds to the Accession the data collected during the previous month.

NCEI存档编号0162181（NCEI Accession 0162181）包含采集自下桑德岛灯塔——美国海岸警卫队（United States Coast Guard，简称USCG）绿色5号日间助航标志——的导航与物理观测数据，该站点为哥伦比亚河河口（华盛顿州/俄勒冈州境内）的固定观测站。本站点的传感器以高频采样间隔对近岸海域的电导率（CONDUCTIVITY）、观测深度（DEPTH - OBSERVATION）、静水压力（HYDROSTATIC PRESSURE）、纬度（LATITUDE）、经度（LONGITUDE）、盐度（SALINITY）及水温（WATER TEMPERATURE）进行观测。海岸带监测与预测中心（Center for Coastal Margin Observation & Prediction）完成了该批数据的采集工作，并将数据提交至NANOOS。NANOOS整合了来自海岸带监测与预测中心及美国西北沿海其他次区域海岸与海洋观测系统的数据，并作为综合海洋观测系统数据组装中心（Integrated Ocean Observing System Data Assembly Centers，简称IOOS DACs）数据管理计划的一部分，将该数据提交至NCEI。该数据集以遵循气候与预报元数据公约（Climate and Forecast，简称CF）及数据发现属性公约（Attribute Convention for Data Discovery，简称ACDD）的netCDF格式文件对外发布。美国国家环境信息中心（National Centers for Environmental Information，简称NCEI）每月会将上月采集的新增数据补充至该存档编号对应的数据集内。
