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) | -0.00189 | -0.00327 | |
Oxygen ml/L (dual Seabird SBE43) |
y = 1.0982x+0.0264 R² = 0.9993 |
y = 1.0421x + 0.0058 R² = 0.9996 |
|
Oxygen umol/Kg (dual Seabird SBE43; 2° O2 Calib Off) |
y =1.099x+1.2798 R² = 0.9993 |
y = 1.0429x + 0.3795 R² = 0.9996 |
|
Single sensors | Linear | Polynomial | |
Nitrate - ISUS 4sec ave voltage vs Bottle NO3 (Satlantic ISUS v3 SN111) Cast 001 - 036 |
y = 32.427x-2.435 R² = 0.9142 |
Please note that the MBARI-ISUS light tube lost its reflective sensor surface (mirror). Although the ISUS light emitter was working, the reflected signal was not detected properly. A replacement optical tube was installed post-cruise once the problem was discovered. | |
Fluorometer - linear & polynomial regressions |
y= 10.817x-0.4933 R² = 0.8052 |
y = 12.364x2 + 4.9555x - 0.1677 R² = 0.867 |

Project: | CalCOFI 1708SR (UNOLS SR1712) on SIO RV Sally Ride |
Summary: |
CalCOFI 1708SR sailed on SIO RV Sally Ride at 1000PDT 01Aug2017 from Nimitz Marine Facilities (MarFac) San Diego. Returning to San Diego 0930PDT 16Aug2017, RV Sally Ride was offloaded upon arrival to MarFac. All 73 scheduled stations - 65 standard stations & 8 SCCOOS 20m stations were occupied (see station map). As planned, two stations were dropped - 93.3 120 & 91.7 26.4 - to complete the scheduled stations plus mooring deployment. To maximize ship transit efficiency, saving 10+hrs, RV Sally Ride sailed north after sta 83.3 51.0 to sta 80.0 60.0. With the mooring deployment scheduled for sta 80.0 55.0, this station was scheduled after sta 76.7 49.0 & the pickup of Uwe Send's mooring team at Avila Beach. Eight in-shore stations off Santa Barbara & Ventura were occupied after sta 80.55, as we transited south - see map below for actual cruise track. Please refer to the preliminary data plots web page and data links below for preliminary data. In addition to DIC, pH, NCOG sampling, 1708SR included oxygen stable isotope seawater samples collected on 18 stations (see map for station sampled). |

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.
