The "pfloatProfiles" collection contains ocean temperature and
salinity data measured by profiling floats. The data have been
contributed by a number of researchers. The data have undergone
whatever data quality checks are carried out by the originator
only. None of the data have passed through standardized
procedures. Users are cautioned to keep this in mind when using the
data.

For more information see the "pfloat" directory of the WOCE Global
Data, Version 3.0 disks.
