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 ...
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 ...
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 ...
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 ...
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.
NCOG Sampling Method.
(California Cooperative Oceanic Fisheries Investigation, La Jolla, CA, 2015)
NCOG Sampling For DNA and RNA Samples for NCOG Project
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, ...
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 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 ...
SeasaveV7 Setup & Data Acquisition.
