The coastal upwelling region west of Vancouver Island, Canada, was sampled from July 15 to 23, 1998. Data includes dissolved inorganic carbon, alkalinity, temperature, salinity, dissolved oxygen, silicate, nitrate, and phosphate from discrete samples and profiles collected aboard the Canadian Coast Guard Ship John P. Tully. The dataset, archived by NOAA NCEI, contrasts inner-shelf buoyancy currents, outer-shelf, and slope regions under different wind regimes.
Use Cases
- Modeling biological carbon drawdown based on measured pCO2 and nutrient concentrations.
- Analyzing the relationship between primary productivity and cell size dominance mentioned in the description.
- Comparing carbon and nutrient dynamics between inner-shelf currents and outer-shelf regions during upwelling and downwelling.
- Investigating remineralization effects on carbon concentrations in coastal waters constrained by bathymetry.
Strengths
- Data covers a specific, intensive 9-day sampling period in July 1998.
- Includes multiple key oceanographic variables: DIC, alkalinity, temperature, salinity, dissolved oxygen, silicate, nitrate, and phosphate.
- Analysis contrasts three distinct regions (inner-shelf current, outer-shelf, slope) and two wind regimes (upwelling, downwelling).
Limitations
- Last updated 1998-07-23; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
