Chemical and physical oceanographic data were collected from the Hudson research vessel in the Davis Strait, Labrador Sea, and North Atlantic Ocean during June and July 2002. Robert Gershey of BDR Research Ltd and E. Peter Jones of the Bedford Institute of Oceanography gathered discrete samples and profiles measuring dissolved inorganic carbon, alkalinity, chlorofluorocarbons, and nutrients. These observations contribute to the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program's effort to quantify changes in heat, freshwater, and carbon dioxide storage.
Use Cases
- Calculate ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
- Track the distribution and decline of anthropogenic chlorofluorocarbons (CFC-11, CFC-12, CFC-113) in the North Atlantic.
- Analyze nutrient cycling and ocean productivity based on nitrate, phosphate, and silicate concentrations.
- Study water mass properties and circulation using concurrent temperature, salinity, and dissolved oxygen profiles.
Strengths
- Data includes multiple key parameters for ocean carbon studies, specifically dissolved inorganic carbon (DIC) and total alkalinity (TA).
- Measurements cover a specific cruise (CLIVAR_AR07W_2002) with a defined temporal range from 2002-06-23 to 2002-07-19.
- Spatial coverage spans three distinct oceanic regions: Davis Strait, Labrador Sea, and North Atlantic Ocean.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for large-scale modeling.
