The Arctic Ocean and Northwest Passage were surveyed during a cruise from August 3 to August 18, 1997. Data includes dissolved inorganic carbon, alkalinity, chlorofluorocarbons, nutrients, and temperature profiles collected via CTD and bottle instruments. The dataset was compiled by researchers from the Bedford Institute of Oceanography as part of the CARINA (CARbon dioxide IN the Atlantic Ocean) international synthesis project.
Use Cases
- Modeling ocean acidification trends based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing historical chlorofluorocarbon (CFC) distributions as tracers for ocean circulation.
- Studying nutrient dynamics (nitrate, phosphate, silicate) in Arctic marine ecosystems.
- Calibrating biogeochemical models using concurrent profiles of temperature, salinity, and dissolved oxygen.
Strengths
- Data covers a specific 16-day research cruise in August 1997, providing a focused temporal snapshot.
- Includes multiple core ocean chemistry variables: dissolved inorganic carbon, alkalinity, CFCs, nutrients, and physical properties.
- Part of the CARINA international synthesis project aimed at producing an internally consistent data set.
Limitations
- Last updated 1997-08-18 00:00:00; 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.
