CTDEDIT was used to remove some records around 5db; salinity was cleaned. The only bottles were from around 11db.The comparison with bottle data showed a lot of scatter; salinity is considered +/-0.005psu. The transmissivity channel was removed because the data was bad. !----1---- ---2---- ---3---- -4-- !Pressure Temperat Salinity Numb ! ure: :T0:C0 er_o !
