Aligned and Depth Binned profile data that are collecting profile data are described here. This data product is generated on-demand / on-the-fly and with several improvements over Aligned and Depth-Binned Profile Data (Legacy). A profile is a series of measurements made throughout the water column grouped by each pass through the water, known as a 'cast', as opposed to continuous time series data. Profiles of the water column can be created by performing casts with instruments. Casts involve lowering an instrument down into the water and back up again while it is making measurements. Cast detection or delineation is performed automatically with manual oversight, contact us for further details. The measurements from the various sensors attached to and within the instrument are processed to filter, smooth, align, and average data into depth bins. Information about the data processing is included in the header of the data product. Specifically, the default processing steps are:

Behaviour when no data is retrieved

If the requested search range does not contain any data a file is created with "Missing Data Detected" for each sensor column in the file. These "Missing Data Detected" files are generated for each deployment in the search range. An example of this type of missing data file can be seen below.
