Profile discrete measurements of dissolved inorganic carbon, total alkalinity, CTD salinity, and temperature collected aboard the R/V Xuelong during the 2012 Chinese Arctic Research Expedition. The data covers the western Arctic Ocean and Bering Sea from July 10 to September 12, 2012. The dataset is part of an international collaboration between U.S. and Chinese scientists studying water column carbonate chemistry.
Use Cases
- Modeling ocean acidification based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing water column properties based on CTD salinity and temperature profiles.
- Studying seasonal carbonate chemistry variability in the Arctic Ocean and Bering Sea.
- Calibrating regional biogeochemical models based on discrete sample data.
Strengths
- Data covers a specific cruise period from 2012-07-10 to 2012-09-12.
- Includes multiple chemical and physical parameters: dissolved inorganic carbon, total alkalinity, salinity, and temperature.
- Dataset originates from an international scientific collaboration.
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 and temporal bias inherent to a single summer cruise.
