Title: NPBY1 - Point Wells: L3 Depth Gridded Data - 0.25 meter

Summary:
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.
