Other instrumental errors, including variations in alignment due to descent rate variations, are expected to cause errors in salinity of up to 0.01psu in high gradient areas and much smaller errors at depth. The dissolved oxygen channel was removed from the file because there was no recalibration sampling during this cruise. !--1--- ---2---- ---3---- -4-- !Pressu Temperat Salinity Numb !re ure: :T0:C0 er_o !
