CTD sensor corrections derived by comparing 4 secs of CTD sensor data (prior to bottle closure) to bottle samples | |||
Dual T, S, & O2 | Primary Sensor | Secondary Sensor | |
Salinity offset (bottle - CTD salinity; > 350m only; Seabird SBE4) | -0.0011 | -0.0004 | |
Oxygen ml/L (dual Seabird SBE43) | y = 1.053x - 0.0121 R² = 0.9998 |
y = 1.0161x + 0.0053 R² = 0.9999 |
|
Oxygen umol/Kg (dual Seabird SBE43) | y = 1.0545x - 0.3454 R² = 0.9998 |
y = 1.0176x + 0.4011 R² = 0.9999 |

Single sensors | |||
Nitrate - ISUS 4sec ave voltage vs Bottle Nitrate (Satlantic MBARI-ISUS v2) | y = 27.413x - 3.6183 R² = 0.9934 |
||
Fluorometer - polynomial & linear regressions | y = 6.7287x - 0.2248 R² = 0.6925 |
y = 5.4518x2 +5.5523x - 0.1786 R² = 0.6940 |

General notes: | |||
NOAA RV Bell M. Shimada had severe engine problems that required the ship return to San Diego for repairs after completing 36 stations. Unfortunately, the length of repairs put the remainder of the cruise out of the winter cruise target date window. No other ships were available - SIO RV New Horizon was in dry dock. These are from the final bottle data comparisons. Cast Notes: Cast 000 - Sound velocity acoustics calibration cast in San Diego Bay, 10m; pr sensor offset applied post-cast -0.150 Cast 002 - no ISUS data, no battery? Shallow SCCOOS station Cast 003 - ISUS data looks bad, battery? Shallow SCCOOS station Cast 005 - Bottle #17 mistrip, no closure Cast 007 - artificial (caused by winch wire jerk) chl spike at 20m Cast 008 - Eventlog lost gps at depth, CTDatDepth event position may be bad; gps data in CTD data files should be fine Cast 013 - lots of ship roll Cast 015 - bottle #11 tripped early; extra marker at 11, skipped marker at 12, corrected post-cast Cast 016 - CTD yo-yo'd on upcast between 125 & 140, 125m bottle tripped then CTD was lower to get forgotten 140m bottle Cast 019 - bottle #23 no closure, winch communications issues slowed the cast Cast 020 - extra surface bottle tripped for test case Cast 023 - (Superbowl Sunday!) Cast 024 - raining, fairly calm Cast 026 - file named incorrectly, corrected post-cast Cast 027 - no nav file created Cast 034 - two markers/one bottle at terminal depth; missed tripping 5m bottle (cast depth <75m) Cast 035 - Santa Monica Basin, bottle tripped first before CTDatDepth event logged because of close proximity to the bottom. Cast 036 - last cast, ship engine problem required return to San Diego.
