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. The sensors had been calibrated at the factory fairly recently, so drift is likely small. 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.
