Water temperature and salinity from profiling float 67898

The salinity profiles have been checked for spurious points as well as sensor drift. The drift correction has not been applied to each profile so ther is still a use at your own risk warning on them. Some original files had data thrown away and so filled the data with null values. These profiles have been removed from the data included here. Also if a temperature or salinity was missing, the pressure level has been removed from the profiles here.
