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. There was no recalibration sampling during this cruise. The dissolved oxygen data in the CTD files was recalibrated using the results of cruise 2005-30. During that cruise bottle comparisons showed that DO was: • ±0.4ml/l from 2 - 125m • ±0.3ml/l from 125 – 200m • ±0.1ml/l below 200m *CALIBRATION $TABLE: CORRECTED CHANNELS !
