| Dual T, S, & O2 | Primary Sensor | Secondary Sensor | |
| Salinity offset (bottle - CTD salinity; > 350m only; Seabird SBE4) | 0.00033 | 0.00170 | |
| Oxygen ml/L (dual Seabird SBE43) |
y = 1.04200x + 0.0002 R² = 0.9990 |
y = 2.3898x - 3.9207 R² = 0.9824 |

CalCOFI 2007SR General Cruise & Cast Notes: CalCOFI 2007SR sailed on Sally Ride at 0800 PDT 13 July 2020 from Marfac. All 75 science stations were completed. 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.
