26 Years of Mooring Data from Olympic Coast National Marine Sanctuary

Olympic Coast National Marine Sanctuary (OCNMS) on the northwestern edge of Washington has maintained oceanographic moorings measuring surface and subsurface water properties at five cross-shelf lines from 2000 to present. Temperature, salinity, dissolved oxygen, water velocity, and pressure are measured offshore of Cape Elizabeth, Kalaloch, Teahwhit Heat, Cape Alava, and Makah Bay, with varying availability depending on location and year. The moorings collect data from late spring to late fall on the 15-meter and 27- or 42-meter isobaths (the Kalaloch mid-depth mooring is at 27 meters depth). Moorings have also been deployed at 50 meters at Kalaloch; 65 meters at Cape Alava, Teahwhit Head, and Cape Elizabeth; and 100 meters at Cape Alava during some years. Temperature measurements occur at 5-10 meter intervals throughout the water column at all locations, while the other variables are measured near the surface and/or bottom. This dataset includes multiple NetCDF files with data and quality flags for each OCNMS mooring site. The quality flags are defined by the U.S. Integrated Ocean Observing System (IOOS) Quality-Assurance/Quality Control of Real-Time Oceanographic Data (QARTOD). The site name convention is the geographic location abbreviation followed by the water depth, in meters, at the mooring (Makah Bay: MB015 and MB042; Cape Alava: CA015, CA042, CA065, and CA100; Teahwhit Head: TH015, TH042, and TH065; Kalaloch: KL015, KL027, and KL050; Cape Elizabeth: CE015, CE042, and CE065). The data are organized in directories as follows: "Hourly_Processed_Files" contains hourly-averaged temperature, salinity, dissolved oxygen, eastward velocity, northward velocity, and pressure and the corresponding quality flags for each variable at all available depths from 2000–2025; "Record_Means" contains record means computed using all available years of data; "Raw_Files" contains the data before computing averages and applying quality flags; and "CSV_Files" contains plain-text ASCII comma-separated value files for each variable at each mooring containing all hourly values with “pass” or “suspect” flags.奥林匹克海岸国家海洋保护区（Olympic Coast National Marine Sanctuary, OCNMS）坐落于华盛顿州西北沿海区域，自2000年起至今，持续在5条跨陆架断面上部署海洋学锚系设备，于春末至秋末期间对表层及次表层海水属性开展监测。该系统在伊丽莎白角（Cape Elizabeth）、卡拉洛奇（Kalaloch）、特威特黑德角（Teahwhit Head）、阿瓦洛普角（Cape Alava）与马卡湾（Makah Bay）近岸海域布设观测站点，各站点的数据可用性因地理位置与观测年份存在差异。 锚系设备的布放水深涵盖15米、27米及42米等深线（其中卡拉洛奇的中层锚系水深为27米）；此外卡拉洛奇站点还增设了50米水深的锚系；阿瓦洛普角、特威特黑德角及伊丽莎白角站点设有65米水深的锚系；部分年份还在阿瓦洛普角部署了100米水深的锚系。所有观测站点的水温数据在水柱中以5-10米的间隔分层采集，其余观测变量（盐度、溶解氧、海流流速、压强）则仅在近表层和/或近底层进行监测。 本数据集包含多份NetCDF文件，涵盖各OCNMS锚系站点的观测数据与质量控制标记。质量控制标记依据美国综合海洋观测系统（U.S. Integrated Ocean Observing System, IOOS）制定的《实时海洋学数据质量保证/质量控制规程》（Quality-Assurance/Quality Control of Real-Time Oceanographic Data, QARTOD）完成定义。 站点命名规则为：地理位置缩写后接锚系所在水深（单位：米）。具体示例如下：马卡湾为MB015、MB042；阿瓦洛普角为CA015、CA042、CA065、CA100；特威特黑德角为TH015、TH042、TH065；卡拉洛奇为KL015、KL027、KL050；伊丽莎白角为CE015、CE042、CE065。 数据按目录分类存储： 1. "Hourly_Processed_Files"：收录2000–2025年所有可用水深下各变量的逐小时平均数据（水温、盐度、溶解氧、东向流速、北向流速、压强）及对应变量的质量控制标记； 2. "Record_Means"：收录基于所有可用年份数据计算得到的序列平均值； 3. "Raw_Files"：收录未进行平均处理、未应用质量控制标记的原始观测数据； 4. "CSV_Files"：收录各锚系站点各变量的纯文本ASCII逗号分隔值文件，包含所有逐小时观测值及对应的"通过（pass）"或"可疑（suspect）"标记。
