Values were only updating about once per second. Other variables updated normally. Pressure was recalibrated by adding 2.3db based on observations of "in water" conductivity values during upcasts when pressure was <0db. Conductivity, Fluorescence and Transmissivity data are nominal and unedited except that some records were removed in editing temperature and salinity. There was no calibration sampling for the SBE25 casts, but there was a test cast run to compare with a cast using an SBE911+. Salinity, temperature and fluorescence from the 2 CTDs were reasonably close; the comparison was not extensive enough to justify recalibration or a statement of accuracy. Channel Oxygen:Dissolved:SBE was recalibrated because values were consistently lower than the SBE911 sensor by about 6%.
