| CTD sensor corrections derived by comparing CTD sensor data, 4sec averages prior-to-bottle closure, to bottle samples | |||
| Dual T, S, & O2 | Primary Sensor | Secondary Sensor | |
| Salinity offset (bottle - CTD salinity; > 350m only; Seabird SBE4) | 0.0038 | 0.00554 | |
| Oxygen ml/L (dual Seabird SBE43) |
y = 0.7984x + 0.0473 R² = 0.9995 |
y = 1.0140x + 0.0410 R² = 0.9994 |
|
| Oxygen umol/Kg (dual Seabird SBE43) |
y =0.7972x + 1.9461 R² = 0.9994 |
y = 1.0130x + 1.6532 R² = 0.9994 |

| Single sensors | Linear | Polynomial | |
|
Nitrate - ISUS 4sec ave voltage vs Bottle NO3 (Satlantic ISUS v3 SN111) |
y = 27.7823x - 28.6637 R² = 0.9973 |

| Fluorometer - linear & polynomial regressions |
y= 8.4271x - 0.2757 |

Please note that the anomalies are based on 50-year harmonics (1949-1999) and these data are 1m binavg Seasoft-processed CTD data that have not gone through thorough quality control checks or bottle corrections. They are presented to give a general impression of current conditions. Final data plots will be published after all data are processed.
