Discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), salinity, oxygen, nutrients, and temperature during the CCGS John P. Tully cruise 2019.23 (EXPOCODE 18DD20190829) in the Salish Sea and off the west coast of Vancouver Island of the North American Pacific coast from 2019-08-29 to 2019-09-06 (NCEI Accession 0252614)

Metadata Updated: November 1, 2023

This dataset consists of data collected during the CCGS John P. Tully cruise 2019.23 (EXPOCODE 18DD20190829) in the Salish Sea and off the west coast of Vancouver Island of the North American Pacific coast from 2019-08-29 to 2019-09-06 as part of the La Perouse Water Properties Survey. Discrete dissolved inorganic carbon (DIC), total alkalinity (TA), salinity, and nutrient samples were taken from rosette casts with 10L Niskin bottles and analysed at the Institute of Ocean Sciences. Discrete samples of dissolved oxygen were also collected and analysed onboard the vessel. CTD profiles were recorded with each rosette cast. DIC and TA samples were placed in cold storage for 1-4 weeks before analysis. A total of 61 DIC and TA pairs were sampled with a 22 percent replication rate. Replicates are not averaged in this dataset and appear individually, indicated by decimal sample ID's (e.g. 26.1, 26.2). The pooled standard deviations (of difference between replicate pairs) were calculated to be 6 umol/kg and 5 umol/kg respectively. Replicates with a QC flag = 3 were included in the pooled standard deviation calculation but replicate pairs with at least one QC flag = 4 (n = 1) were excluded.
