Such errors are likely to be larger than calibration errors. SeaCat salinity errors are expected to be as high as 0.05 units in areas of high gradients. For these data the descent rate was quite steady and temperature and salinity gradients were not extreme, so the error is likely much smaller than that. No calibration sampling was available for this cruise or any other cruise since the last factory calibration. 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. ************************************************************************* !--1--- ---2---- ---3---- --4--- -5-- !Pressu Temperat Salinity Oxygen Numb !re ure :T0:C0 : er_o !
