| Dual T, S, & O2 | Primary Sensor | Secondary Sensor | |
| Salinity offset (bottle - CTD salinity; > 350m only; Seabird SBE4) | -0.0036 | -0.0037 | |
| Oxygen ml/L (dual Seabird SBE43) |
y = 1.0140x + 0.0542 R² = 0.9975 |
y = 1.0515x + 0.0110 R² = 0.9976 |

CalCOFI 2010SR General Cruise & Cast Notes: CalCOFI 2010SR sailed on Sally Ride at 0800 PDT 11 October 2020 from Marfac. 71 of 75 stations were completed. 4 stations were skipped due to weather. CTD General Notes and Problems:
CalCOFI used their 24-10L CTD-rosette with a two-pin termination, cable grip, deck unit, monitor, mouse &. SIO-CalCOFI used Sally Ride's computer and non-uplink deck unit, surface PAR; and wired/wireless data network.
