Dissolved inorganic carbon, pH, alkalinity, temperature, salinity and other variables coll

Discrete sample and profile data for 13 oceanographic variables were collected from the R/V Hudson in the Davis Strait, Labrador Sea, and North Atlantic Ocean from May 6 to May 28, 2011. The data include dissolved inorganic carbon, alkalinity, pH, nutrients, and physical properties like temperature and salinity. Igor Yashayaev and Kumiko Azetsu-Scott of the Bedford Institute of Oceanography collected this data as part of the CLIVAR_AR07W_2011 program.

Use Cases

• Quantifying changes in ocean carbon storage based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing ocean acidification trends using pH and related carbonate system data.
• Studying nutrient distributions and biogeochemical cycles from nitrate, phosphate, and silicate readings.
• Modeling water mass properties and circulation using temperature, salinity, and dissolved oxygen profiles.

Strengths

• Data covers 13 specific chemical and physical oceanographic variables, including ALKALINITY, DISSOLVED INORGANIC CARBON, and NUTRIENTS.
• Measurements were taken during a dedicated research cruise over a 23-day period in May 2011.
• Data collection is part of the systematic international CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
