Legacy Aligned and Depth Binned profile data for sensors that are collecting profile data are described here. 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 with automatically with manual oversight, contact us for further details. The measurements from the various sensors attached to and within the instrument are processed by aligning all sensors for various response lags and then averaging the data into depth bins. The descending portion of the cast is then extracted. This aligned and depth binned process is announced by having "-CORRECTED" appended to the start time in the file name. This data product retrieves consists of one file per cast per device. For example, if three devices perform two casts at the same time this will result in six separate files. These files have a header that defines what each column of data is representing. Each sample of data is preceded by a timestamp. The timestamp is followed by the first column of data. All other columns of data are comma-delimited as can be seen below. This data product is very similar to data product 152 Aligned and Depth-Binned Profile Data (On-Demand), however, each cast and device is a separate file.
Please note that these files are generated beforehand offline and are available through data search Data Search for applicable instruments. Production of these files was superseded by Aligned and Depth-Binned Profile Data (On-Demand).
Please consult individual instruments' documentation for more information.
