Chemical and physical data collected from the HUDSON research vessel in the Davis Strait, Labrador Sea, and North Atlantic Ocean from 2015-05-04 to 2015-05-24. The dataset includes measurements of dissolved inorganic carbon, alkalinity, pH, nutrients, chlorofluorocarbons, and sulfur hexafluoride. Igor Yashayaev and Kumiko Azetsu-Scott of the Bedford Institute of Oceanography collected these data as part of the GOSHIP_AR07W_2015 program.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing changes in ocean acidification based on pH and total alkalinity data.
- Studying nutrient cycles in the North Atlantic based on nitrate, nitrite, phosphate, and silicate concentrations.
- Tracking anthropogenic tracers in the ocean based on chlorofluorocarbon-12 and sulfur hexafluoride levels.
- Investigating physical oceanographic properties based on hydrostatic pressure, salinity, and water temperature profiles.
Strengths
- Data covers a specific 21-day cruise period from May 4 to May 24, 2015.
- Includes 15 distinct chemical and physical variables, such as ammonium, CFC-12, DIC, and dissolved oxygen.
- Associated with a specific international program (CLIVAR Global Ocean Carbon and Repeat Hydrography Program) and cruise ID (HUD2015-006).
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 Davis Strait, Labrador Sea, and North Atlantic Ocean.
