Chemical and physical oceanographic data collected from the Hudson in the Davis Strait, Labrador Sea, and North Atlantic Ocean during May 2007. Kumiko Azetsu-Scott and Ross M. Hendry of the Bedford Institute of Oceanography gathered these discrete sample and profile observations. The dataset includes dissolved inorganic carbon, alkalinity, chlorofluorocarbons, and other variables to quantify changes in ocean carbon dioxide storage.
Use Cases
- Modeling ocean carbon storage and transport based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing historical chlorofluorocarbon (CFC) distributions based on CFC-11, CFC-12, and CFC-113 data.
- Studying nutrient dynamics in the North Atlantic based on nitrate, phosphate, and silicate concentrations.
- Assessing ocean acidification trends based on total alkalinity and dissolved inorganic carbon profiles.
- Investigating water column properties based on hydrographic data like temperature, salinity, and dissolved oxygen.
Strengths
- Data covers a specific research cruise (CLIVAR_AR07W_2007) from May 10 to May 27, 2007.
- Includes multiple chemical variables relevant to ocean carbon studies, such as DIC, TA, and CFCs.
- Associated with the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific cruise track in the North Atlantic.
