Aligned and Depth-Binned Profile Data (On-Demand)

Aligned and Depth Binned profile data that is formed into a text file at the time of request for sensors that are collecting profile data are described here. A profile is a series of measurements made throughout the water column. 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. The measurements from the various sensors attached to and within the instrument are processed by aligning all sensors and averaging the data into depth bins. The descending portion of the cast is then extracted. This data product is only used with aligned and depth binned data and therefore there is no identifier of processing appended to the start time in the file name. This also helps to differentiate between this data product and data product 87. This data product includes data from connected sensors when applicable. If connected sensors have been included this is denoted by having "-ALLCONNECTEDSENSORS" appended to the start time in the file name. This data product retrieves all aligned and depth binned casts within the search range and produces one output file with one or more casts within it. Each cast is prefaced by a header which contains additional information associated with the cast. An example of this header can be seen below. The columns of data are labelled with numbers counting from left to right. Each number is labelled with the type of data contained within it and the associated units. The columns of data are comma-delimited with one space on either side of the comma. This data product is very similar to data product 87, however, each cast and instrument in the search range is included in one file. 

Please note that these files are created on-demand with existing data when they are requested through data search for applicable instruments.

Please consult individual instruments' documentation for more information.

Data Product Options

There are two data product options for this data product for specific devices with other devices having one option. These options are shown to represent the processing that is always applied to this dataproduct and is therefore always selected. Instruments with connected sensors will have both data product options as shown below. While instruments without connected sensors will have one selected data product option which is again shown below.
