There were 2 WetLabs CStar transmissometers in use during this cruise: Channel Transmissometer refers to sensor #1185DR (650nm - red) Channel Transmissometer:Green refers to sensor #1883DG (530nm - green) For comparison with other Institute of Ocean Sciences cruises, note that the transmissometer wavelength is 650nm unless otherwise stated. This was the first use of the conductivity sensors on this CTD since they were last serviced at the factory. The primary salinity compared well with samples and the comparison of dissolved oxygen with samples compared well with its previous use during 2025-001. 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. To get an estimate of the accuracy of the SBE DO data during downcasts (after recalibration), a rough comparison was made between downcast SBE DO and upcast titrated samples. Some of the difference will be due to problems with flushing of Niskin bottles and/or analysis and sampling errors, so the following statement likely underestimates SBE DO accuracy. Downcast (CTD files) Oxygen:Dissolved:SBE data for both CTDs for this cruise are considered, very roughly, to be: ±0.50 mL/L from 10-50db (generally too high in mixed layer) ±0.30 mL/L from 50db to 100db ±0.10 mL/L from 100db to 200db ±0.05 mL/L below 200db.
