The CCGS Vector Water Properties Survey cruise 2014-50 collected 98 discrete profile measurements of dissolved inorganic carbon (DIC) and total alkalinity (TA) in the Strait of Georgia and Juan de Fuca Strait from October 27 to 30, 2014. Samples were taken from rosette casts with Niskin bottles and analyzed at the Institute of Ocean Sciences, with CTD profiles recorded for each cast. The dataset also includes measurements of water temperature, salinity, nutrients, and dissolved oxygen.
Use Cases
- Calculate ocean acidification metrics based on paired DIC and TA measurements.
- Model coastal biogeochemical cycles based on concurrent nutrient, oxygen, and salinity profiles.
- Validate or calibrate oceanographic models using discrete water property data collected alongside CTD profiles.
- Assess seasonal or spatial variability in water properties within the Strait of Georgia based on cruise survey data.
Strengths
- Includes 98 paired DIC and TA samples with a 14 percent replication rate for quality control.
- Provides pooled standard deviations for replicate pairs: 0.5 µmol/kg for DIC and 1.3 µmol/kg for TA.
- Data collection is part of a regular sampling program with 3-4 cruises per year, suggesting methodological consistency.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- DIC and TA samples were placed in cold storage for 11 weeks before analysis, which may introduce uncertainty.
