    • Bottle sampling depths. 

      CalCOFI (California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2017)
      The CalCOFI CTD-rosette is equipped with a Sea-Bird Electronic carousel water sampler (SBE 32), a computer-driven, electro-magnetically-released latch system. The 24 ten-liter plastic (PVC) bottles, equipped with epoxy-coated ...

    • CalCOFI CTD FAQ. 

      CalCOFI (California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2017)
      General practices & notes on CalCOFI's Seabird 911/911+ CTD-Rosette

    • CTD Data Algorithms. 

      CalCOFI (California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2017)
      CalCOFI CTD data, particularly the thermodynamic properties, are computed by Seasoft based on EOS-80. Temperatures, typically from the primary temperature sensor, are merged with bottle sample data into station files which ...

    • CTD Data Processing Protocol. 

      CalCOFI (California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2019)
      Please note, the processing methods described use SIO-CalCOFI-developed software (DECODR & BtlVsCTD) to merge and correct Seabird 911+ CTD data with bottle samples. The Seasoft portion of our data processing protocol follow ...

    • CTD General Practices: System Description, Deployment, Data Aquisition, & Maintenance. 

      CalCOFI (California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2017)
      Since 1993, the CalCOFI program has deployed a Seabird 911 CTD mounted on a 24-bottle rosette during seasonal, quarterly cruises off California. The CTD-rosette is lowered into the ocean to 515m, depth-permitting, on 75 ...

    • CTD Setup & Diagnostics: Seabird CTD-Carousel Setup & Deck Unit Diagnostics. 

      CalCOFI (California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2017)
      SIO-CalCOFI’s method of terminating the sea cable uses a custom 4-pin pigtail to terminate a multi-strand conductive wire that allows each individual conductor to be used in any combination. Terminating the sea cable using ...

    • CTD Standard Sensors. 

      CalCOFI (California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2017)
      CalCOFI's primary hydrographic instrument is a Seabird 911+ CTD equipped with dual temperature, conductivity and oxygen sensors mounted on a 24-10L bottle rosette. Additional CTD sensors mounted on the rosette frame include ...

    • CTD System. 

      CalCOFI (California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2017)
      A Sea-Bird Electronics 911plus V2 CTD collects vertical profile data at every CalCOFI station. In addition to being a dual TCO (temperature, conductivity, and oxygen) system, the CTD also interfaces with a transmissometer, ...

    • ISUS Nitrate sensor. 

      CalCOFI (California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2015)
      Since November 2004, a Satlantic ISUS nitrate sensor has been integrated with a Seabird 911+ CTD-Rosette system deployed on CalCOFI cruises. Cruises typically occupy 75 stations, collecting approximately 1400 discrete ...

    • Satlantic ISUS Operation. 

      CalCOFI (California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2017)
