MEASURED VARIABLES:
Column 1: Select variables to include in the extracted file if available in a cast. If no variables are marked
in Column 1, the extracted data file will contain all available variables (default).

Column 2: Select variables that must all be present in a cast. Any variable marked in Column 2 will be
in the extracted file even if not marked in Column 1.

FLAG(S) EXCLUSION:
Note: casts excluded based on quality control flags will still appear in the inventory count/data distribution map. These casts are only removed during the creation of the user requested data files. Exclusion does not work for netCDF output files.
Depth flag affects all measured variables:
Density flag affects temperature and salinity:
