The descent rate of the CTD was extremely noisy with very high deceleration rates which appear to affect the alignment of temperature and conductivity channels. SeaCat salinity is always prone to error due to a mismatch of conductivity and temperature response times, especially when the descent rate is non-uniform. Such errors are likely to be larger than calibration errors. There was no salinity calibration sampling during this cruise. SeaCat salinity errors are expected to be as high as 0.05 units in areas of high gradients. For these data temperature and salinity gradients were not extreme, so the error due to mismatch in T and C is estimated to be up to 0.02 in the top 100m and 0.005 below that, though editing and metre-averaging should reduce the errors somewhat. The dissolved oxygen parameters in the configuration file were updated by using the values for SOC and Voffset that were determined by calibration sampling during cruise 2011-08 in April 2011. There was no calibration sampling during this cruise. Values are apt to be a little low due to drift in sensors. Oxygen:Dissolved:SBE data are unedited except that some records were removed in editing temperature and salinity, and a few large spikes were removed. ******************************************************************************* !--1--- ---2---- ---3--- --4--- --5-- -6-- !Pressu Temperat Salinit Oxygen Oxyge Numb !re ure: y:T0:C0 : n: er_o !
