Discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), salinity, oxygen, nutrients, and water temperature during the CCGS John P. Tully Line P cruise (EXPOCODE 18DD20210824) off the west coast of Vancouver Island from 2021-08-24 to 2021-09-07 (NCEI Accession 0300980)

These data were collected from the west coast of Vancouver Island, between August 24th and September 7th 2021, as part of the Line P Water Properties Survey led by Marie Robert. Discrete dissolved inorganic carbon (DIC), total alkalinity (TA), salinity, and nutrient samples were taken from rosette casts with 10L Niskin bottles and analyzed at the Institute of Ocean Sciences. Discrete samples of dissolved oxygen were also collected and analyzed onboard the vessel. CTD profiles were recorded with each rosette cast. DIC/TA samples were placed in cool storage after collection and returned to the shore-based lab for analysis. Oxygen units were converted to µmol/kg when reported in ml/L. Nutrient concentrations were converted to µmol/kg from µmol/L. The raw data and other supporting documents can be obtained from https://www.waterproperties.ca/.
