CTDEDIT was used to remove surface records to 3.3db and to clean salinity. There was no salinity calibration sampling. Salinity for this cruise has been edited but large errors likely remain. SeaCat salinity is prone to error due to mismatch of conductivity and temperature response times, especially when the descent rate is non-uniform. These errors are likely to be much larger than calibration errors. SeaCat salinity errors are expected to be as high as 0.05units in areas of high gradients. !--1--- ---2---- ---3---- -4-- !Pressu Temperat Salinity Numb !re ure: :T0:C0 er_o !
