For consistency, the upcast data was selected for archiving for all casts. The salinity calibration is within 0.001psu, but there are other errors due to many stops for bottles. Away from the stop depths the errrors are expected to be on the order of 0.01psu in high gradient areas and much smaller at depth. The dissolved oxygen data in the CTD files should be considered • not reliable in top 2m • ±0.4ml/l from 2 - 125m • ±0.3ml/l from 125 – 200m • ±0.1ml/l below 200m *CALIBRATION $TABLE: CORRECTED CHANNELS !
