Continuous sea surface measurements of partial pressure of carbon dioxide (pCO2), temperature, and salinity collected from a buoy off the central coast of British Columbia. Data collection began in May 2018 and extends to November 2025, with measurements taken every 30 minutes using a Battelle Seaology (MApCO2) System. The dataset is part of the Hakai Institute's directive to advance understanding of carbon cycling in northeast Pacific coastal settings.
Use Cases
- Modeling ocean acidification trends based on continuous pCO2 measurements.
- Analyzing seasonal and long-term variability in coastal carbon cycling based on multi-year time-series data.
- Studying the relationship between seawater temperature, salinity, and carbon dioxide content in a coastal setting.
- Monitoring marine boundary layer CO2 content for climate change research.
Strengths
- Continuous measurements taken every 30 minutes since May 2018.
- Data spans over seven years, from 2018-05-01 to 2025-11-24.
- Focuses on a specific coastal location, Kwakshua Channel near Fitz Hugh Sound.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last metadata update was 2026-03-05.
