Preliminary Plots
Please note: these data are 1m-bin-average Seasoft-processed CTD data that have not gone through quality control checks or bottle corrections. Anomalies are based on 50-year harmonics (1949-1999).

CTD Processing Notes
CTD Sensor Corrections:
Derived by comparing sensor data (4 sec avg prior-to-bottle closure) to bottle samples.
Dual Salinity (Seabird SBE4) and Oxygen (Seabird SBE43) Sensors
| PRIMARY SENSOR | SECONDARY SENSOR | |
|---|---|---|
| Salinity offset (bottle - sensor; > 350 m) | -0.00235 | 0.00061 |
| Oxygen ml/L | y =1.0353x - 0.0064; R² = 0.9998 | y = 1.0632x - 0.026; R² = 0.999 |
| Oxygen umol/Kg | y = 1.0369x - 0.1339; R² = 0.9998 | y = 1.0648x - 0.9879; R² = 0.999 |
Single Nitrate (Satlantic ISUS v3 SN111) and Fluorescence (Wetlabs ECO AFL/FL) Sensors
| LINEAR | POLYNOMIAL | |
|---|---|---|
| Nitrate | y = 28.632x - 4.3398; R² = 0.9955 | Please note: the ISUS was rebuilt prior to this cruise so early data may display lamp "burn-in". Sta-corrected estimated nitrate should be good. |
| Fluorescence | y = 7.9809x - 0.2728; R² = 0.7837 | y = 26.251x² + 1.9787x - 0.0356; R² = 0.829 |
Regressions:
Please note: these regressions are generated from preliminary CTD vs bottle data and will be reprocessed once final bottle data are available. CTD temperatures and salinities do not usually change but oxygen, chlorophyll-a, and nitrate may change significantly after QAQC. Questionable or mistrip bottle data are removed from these comparisons but may be visible on the CTD.csv plots. For this cruise and future cruises, both primary & secondary sensor profiles vs bottle data will be generated and archived in the downloadable CTD+Bottle data files. These plots are under the “csv-plots\Primary” & “csv-plots\Secondary” subdirectories.
