Transmissivity: The data are nominal and unedited. The pressure sensor is considered ±1db. The salinity calibration is considered ±0.005psu except in areas of rapid temperature change where the salinity has been edited heavily and should be considered ±0.02psu. The dissolved oxygen data was removed because the data look bad and there was no calibration sampling. *************************************************************** !--1--- ---2---- --3-- ---4--- ---5---- -6-- !Pressu Temperat Trans Fluores Salinity Numb !re ure: missi cence: :T0:C0 er_o !
