Arctic Ocean Carbon and Hydrographic Measurements from Cruise MR00-K06, 2000

Chemical and physical oceanographic data collected from the MIRAI research vessel in the Arctic Ocean, Beaufort Sea, and Bering Sea from 2000-08-03 to 2000-10-13. The data include dissolved inorganic carbon, alkalinity, nutrients, dissolved oxygen, temperature, and salinity, measured using CTD, Coulometer, and bottle sampling. These observations were collected by researchers from JAMSTEC and the Meteorological Research Institute as part of the PACIFICA international data synthesis project.

Use Cases

• Modeling ocean acidification based on dissolved inorganic carbon and alkalinity measurements.
• Studying nutrient cycling in Arctic waters based on nitrate, phosphate, and silicate data.
• Analyzing water mass properties based on concurrent temperature, salinity, and hydrostatic pressure profiles.
• Investigating carbon system dynamics based on paired dissolved inorganic and organic carbon observations.

Strengths

• Includes multiple key carbon system parameters (DIC, alkalinity, DOC) measured concurrently.
• Data spans a specific research cruise (MR00-K06) over a defined 2-month period in 2000.
• Measurements cover three distinct geographic regions: the Arctic Ocean, Beaufort Sea, and Bering Sea.

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.
• Data is from a single cruise in 2000; temporal coverage is limited.
