East China Sea Carbon and Hydrographic Profiles from 2008

The East China Sea is the geographic scope for this dataset of discrete water samples and profiles collected aboard the OCEAN RESEARCHER I from January 2 to 9, 2008. It includes measurements of dissolved inorganic carbon, total alkalinity, pH, dissolved oxygen, nutrients, and physical parameters like temperature and salinity. Wen-Chen Chou of National Taiwan Ocean University collected the data as part of the CLIVAR_ORI_885_20080102 cruise for the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Use Cases

• Modeling ocean acidification dynamics based on concurrent pH, alkalinity, and dissolved inorganic carbon measurements.
• Analyzing nutrient cycling and primary productivity based on chlorophyll a, nitrate, nitrite, phosphate, and silicate data.
• Studying water mass properties and circulation based on high-resolution CTD profiles of temperature, salinity, and pressure.

Strengths

• Includes a focused suite of 12 key ocean carbon and hydrographic variables measured concurrently.
• Data collection occurred over a specific 8-day period in January 2008, providing a temporally constrained snapshot.
• Measurements were taken using specialized instruments like an alkalinity titrator and a non-dispersive infrared DIC analyzer.

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 may reflect geographic and temporal bias inherent to a single, short-duration cruise in the East China Sea.
