The data in the dataset include dissolved inorganic carbon (DIC), total alkalinity (TA), water temperature, salinity, dissolved oxygen concentration and nutrients. The majority of the cruises from 1990 to 2015 have been reported elsewhere as individual files (e.g., GLODAP and PACIFICA databases). This dataset is a combination of the available cruises into a single database, and extended the time series to June 2019. A secondary quality control was performed and the quality flags revised. Additionally, the suggested PACIFICA corrections for salinity, oxygen, dissolved inorganic carbon and nutrients were applied. Oxygen units were converted to µmol/kg when reported in ml/L. Nutrient concentrations were converted to µmol/kg from µmol/L.

Hydrographic Office Publication No. 607 (1955). Depth estimates have an approximate accuracy of +-5 m for depths less than 1000 m, and +-0.5% of depth for depths greater than 1000 m. In the paper related to this database, which concerns the top 600 m of the water column, we assumed that 1m = 1dbar and did not transform from depth into pressure.; Uncertainty: plus minus 5 m for depths less than 1000 m, and +-0.5% of depth for depths greater than 1000 m; Researcher institution: Institute of Ocean Sciences Parameter or Variable: Dissolved Oxygen; Abbreviation: OXYGEN_UMOL_KG; Unit: µmol/kg; Observation type: Profile; Sampling instrument: Rosette; Niskin bottle 10L.; Analyzing instrument: The dissolved oxygen analyses were done in the shipboard laboratory by a micro-Winkler procedure of Carpenter (1965) with a starch end-point tritration.; Detailed sampling and analyzing information: Oxygen samples were analyzed at sea using an automated Winkler titration system with modifications based on Carpenter (1965) and adhering to WOCE protocols.

NOAA National Centers for Environmental Information custodian carbon dioxide (CO2) gas analyzer carbon dioxide (CO2) gas analyzer measures gaseous carbon dioxide Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.

Name : PARIZEAU Flag : CANADA - CA (ISO Country Code) Call Sign : CGBS Title : CCGS Platform Class : 31 Research vessel IMO : 6711728 Commissioned Date : 1967 Decommissioned Date : 2001 Current Length : 57.8 Built : 1967 Notes : Named 2001-04 in 2003 and Destiny Empress in 2005 Additional Information Sources: - http://en.wikipedia.org/wiki/CCGS_Parizeau - http://www.shipspotting.com/gallery/photo.php?lid=2241 General Comments: From Miramar: 2001-04 in 2003 and Destiny Empress in 2005 Parizeau served with DFO's Pacific Region from 1966 until 1992 at the Institute of Ocean Sciences, Sidney, BC when she was transferred to DFO's Maritime Region where she was attached to the Bedford Institute of Oceanography, Dartmouth. Parizeau served in the DFO's Maritime Region as a replacement vessel for her soon to be decommissioned sister CSS Dawson. Following the transfer of the Canadian Coast Guard to DFO in 1995 and the merger of the DFO science and enforcement vessels into CCG, the Parizeau's prefix was changed from CSS to CCGS (Canadian Coast Guard Ship), the superstructure colour scheme was changed from science vessel white, with a buff coloured funnel to the Canadian Coast Guard red hull and white superstructure colour scheme. Parizeau crew members became employees of the Canadian Coast Guard, a Special Operating Agency of the Department of Fisheries and Oceans Canada. Parizeau ceased government science programs in June, 2000.
