ORCA4 - Dabob Bay: L3 Depth Gridded Data - 0.25 meter

The Northwest Environmental Moorings program maintains
a number of buoys thoughout the Puget Sound region, taking regular profiling
casts with a winched CTD attached to a fixed mooring. These profiles measure
water pressure, water temperature, and conductivity. Depending on the mooring
configuration, additional instruments are added to take further measurements,
which can include dissolved oxygen, nitrate concentrations, fluoroescence
(a proxy measurement for chlorophyll concentrations), and turbidity.

This data has converted raw profiles into a gridded data product. Data from the downcast (i.e., from surface to maximum depth) is extracted, and used to grid each variable to pre-defined pressure levels. Quality control flags are used to improve gridded data quality. Bad data is removed during gridding, while suspect data is flagged. Using the pressure-gridded data, corresponding hydrostatic depths are calculated. From these hydrostatic depths, the data is then interpolated onto fixed depth levels.

This dataset has historical data, and adds new data shortly after any additional casts
have been performed. Data quality delay is usually less than 6 hrs.

西北环境锚系项目在普吉特湾地区维护着一系列浮标，通过固定锚系连接的绞车式CTD（海水温度、盐度、深度测量仪）进行定期的剖面测量。这些剖面数据测量了水压、水温、电导率。根据锚系配置，可能还会添加额外的仪器进行进一步测量，包括溶解氧、硝酸盐浓度、荧光（作为叶绿素浓度替代指标的测量）和浑浊度。该数据集将原始剖面数据转换为网格化数据产品。向下投掷（即从表面到最大深度）的数据被提取出来，并用于将每个变量网格化到预定义的压力水平。质量控制标志用于提高网格化数据质量。在网格化过程中，不良数据被移除，而可疑数据则被标记。利用压力网格化数据，计算相应的静水深度。从这些静水深度出发，数据随后被插值到固定的深度水平。该数据集包含历史数据，并在任何额外测量进行后不久添加新的数据。数据质量延迟通常少于6小时。数据属性：版本=2，netcdf=4.9.0，hdf5=1.12.2。作者：Seth Travis。浮标标识：ORCA4。浮标纬度：47.80341666度北纬。浮标经度：-122.80291666度东经。浮标名称：Dabob湾。浮标参考编号：4。数据类型：时间序列剖面。剖面变量：测量次数。时间序列变量：浮标名称、纬度、经度。引用：华盛顿大学西北环境锚系数据，2005-2024；https://nwem.apl.washington.edu/，由西北网络海洋观测系统协会（NANOOS，https://www.nanoos.org）和华盛顿州海洋酸化中心（WOAC，https://oceanacidification.uw.edu/）提供支持。联系人：[e-mail]。贡献者电子邮件：[e-mail], [e-mail], [e-mail]。贡献者姓名：Seth Travis, John Mickett, Dana Manalang。贡献者角色：作者、主要研究员、主要研究员。贡献者角色词汇表：https://vocab.nerc.ac.uk/collection/G04/current/。贡献者网址：https://nwem.apl.washington.edu/，https//www.nanoos.org/，https://nwem.apl.washington.edu/。约定：IOOS参数词汇表v2.0（https://mmisw.org/ont/ioos/parameter）。创建状态：华盛顿州。默认数据查询：海水温度[过去30天][0到过去]，海水实际盐度[过去30天][0到过去]，海水sigma_θ[过去30天][0到过去]，海水氧质量浓度[过去30天][0到过去]。默认图形查询：海水温度[过去30天][0到过去]&.draw=surface&.vars=cast_start_time|depth|sea_water_temperature&.yRange=0|105|false。描述：Dabob湾ORCA浮标L3深度网格化数据。特征类型：时间序列剖面。地理空间垂直方向：向下。gts_ingest：false。历史记录：2024年8月24日15:04:41：生成深度网格化数据等。机构：华盛顿大学应用物理实验室的西北环境锚系组。关键词词汇：GCMD科学关键词。修改日期：2024年8月24日15:04:41。参考：联合国教科文组织1983年——海水基本性质计算算法；https://unesdoc.unesco.org/ark:/48223/pf0000059832_eng。源URL：（本地文件）。标准名称词汇：CF标准名称表v70。水深：105米。世界气象组织平台代码：46122。
