Data Processing Notes: ---------------------- Dissolved Oxygen data are nominal and unedited, except that some records were removed in editing temperature and salinity. There was no calibration information available; little drift is expected for the May casts since the sensors had been very recently recalibrated at the factory. For the July and September casts there may have been some drift. The soak at the surface was sometimes shorter than recommended for good dissolved oxygen equilibration, so the near-surface data may be of lower quality than usual.
