ORCA2 - Hoodsport: L3 Depth Gridded Data - 1.00 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.

西北环境锚泊项目在普吉特湾地区维持了一系列浮标，并定期使用固定锚泊上的绞车CTD进行剖面测量。这些剖面测量包括水压、水温及电导率。根据锚泊配置的不同，还会增加额外的仪器以进行进一步的测量，这些测量可能包括溶解氧、硝酸盐浓度、荧光（氯磷浓度的一种代理测量）以及浑浊度。该数据集将原始剖面数据转换成了网格化数据产品。下投数据（即从水面至最大深度）被提取出来，并用于将每个变量网格化至预定义的压力水平。质量控制标志被用于提升网格化数据的质量。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，相应的静压力深度被计算出来。基于这些静压力深度，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，并在进行任何额外投放后不久添加新的数据。数据质量延迟通常不超过6小时。
