NOTE: While the SBE fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples, particularly for casts far from shore. It is recommended that users check extracted chlorophyll values where available. Calibration sampling for this cruise, and others that have used this CTD since the sensors were last serviced, have been limited in quantity and comparisons have not been consistent. Rough estimates of drift were made based on post-cruise calibrations in early 2024. The comparison of salinity samples with CTD salinity were in line with the post-cruise calibration and the comparison from one other cruise, so they were used for recalibration. The comparison of dissolved oxygen from the CTD and samples was confusing with results at depth consistent with the post-cruise calibration, but near-surface values appearing to be low by up to 0.1mL/L. Surface saturation also suggests that surface values may be low by about 1%. The SBE DO sensor has a fairly long response time so data accuracy is not as high when it is in motion as it is during stops for bottles. This will be especially true when vertical DO gradients are large. There was insufficient dissolved oxygen sampling to make a detailed estimate of errors in channel SBE Dissolved Oxygen.
