CTD Data Algorithms.
(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.
(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 Standard Sensors.
(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.
(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, ... -
Dissolved oxygen.
(California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2014)The amount of dissolved oxygen in seawater is measured using the Carpenter modification of the Winkler method. Carpenters modification (1965) was designed to increase the accuracy of the original method devised by Winkler ... -
Distance From Shore.
(California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2013)Distance = Distance from shore in nautical miles. The CalCOFI database includes a calculated distance-from-shore value used primarily for vertical section plots published in the hydrographic data reports. CalCOFI line ... -
ISUS Nitrate history.
(California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2017)The original methods description was written Feb 2010 by J. Wilkinson. Changes to the method or instrument are listed below. -
ISUS Nitrate sensor.
(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 ... -
Line.Sta Algorithms.
(California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2014)Converting between geographic coordinates in latitude and longitude and the line and station sampling pattern of the California Cooperative Fisheries Investigations (CalCOFI) program is a commonly required task for conducting ... -
NCOG Sampling Method.
(California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2015)NCOG Sampling For DNA and RNA Samples for NCOG Project -
SeasaveV7 Setup & Data Acquisition.
(California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2017)SeasaveV7 on Windows 7 CTD Operator's Cookbook -
Underway Data Processing.

Updating CalCOFI Hydrographic Database.
(California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2019)How to update the CCDB Hydrographic Database in MySQL In addition to ERDDAP, SIO-CalCOFI has a smaller, queryable, online, hydrographic database. This query form includes bottle-related data only and resides at ...
