The pH:SBE data were removed from casts 1-30 because the cap was left on the sensor. Pressure and depth were corrected by subtracting 0.2db/0.2m based on a deck test and post-cruise calibration. Primary salinity was corrected by subtracting 0.002psu based on the post-cruise calibration. This is slightly less than the bottle comparison suggests, but that was based on very few samples. Dissolved oxygen was corrected by multiplying all values by 1.087 based on the bottle comparison. This is higher than suggested by the post-cruise calibration, but it was based on many bottle samples and may reflect other sources of error such as response time errors. 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. To get an estimate of the accuracy of the SBE DO data during downcasts a rough comparison was made between downcast recalibrated SBE DO and upcast titrated samples. Some of the difference will be due to sample collection and analysis errors, and incomplete flushing of Niskin bottles and small mismatches in depth in the comparison, so the following statement likely underestimates SBE DO accuracy. The low vertical dissolved oxygen gradients should limit the errors. Downcast (CTD files) Oxygen:Dissolved:SBE data for this cruise are considered, very roughly, to be: ±0.25 mL/L from 10 - 100db ±0.10 mL/L below 100db For details on the processing see the report: 2024-034_Processing_Report.doc. ------------------------------------------------------------------------- !--1--- --2--- ---3---- --4-- ---5--- --6--- --7--- ---8--- ---9---- --10-- --11- ----12--- -13- !Pressu Depth Temperat Trans Fluores PAR PAR: pH:SBE: Salinity Oxygen Oxyge Conductiv Numb !re ure: missi cence: Refere Nominal :T0:C0 : n: ity: er_o !
