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) | 0.00033 | 0.00170 | |
Oxygen ml/L (dual Seabird SBE43) |
y = 1.04200x + 0.0002 R² = 0.9990 |
y = 2.3898x - 3.9207 R² = 0.9824 |
|
Oxygen umol/Kg (dual Seabird SBE43) |
y =1.0431x + 0.1487 R² = 0.9990 |
y = 2.3906x - 170.4218 R² = 0.9824 |
|
Single sensors | Linear | Polynomial | |
Nitrate - ISUS 4sec ave voltage vs Bottle NO3 (Satlantic ISUS v3 SN111) |
y = 29.3821x - 11.0190 R² = 0.9865 |
