East China Sea Carbon Chemistry Measurements from Cruise ORI-1086, 2014

National Taiwan Ocean University collected discrete water column measurements of total dissolved inorganic carbon, total alkalinity, pH, salinity, temperature, and nutrients during the R/V Ocean Researcher I cruise ORI-1086. The cruise occurred in the East China Sea from August 20 to August 31, 2014, as part of a long-term observation program. The dataset is hosted by the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling ocean acidification dynamics based on DIC, TA, and pH measurements.
• Studying coastal biogeochemical processes based on nutrient and salinity data.
• Calibrating satellite-derived ocean chemistry products based on in-situ discrete measurements.
• Analyzing seasonal or spatial variability in carbon parameters in the East China Sea.

Strengths

• Includes key ocean acidification variables (DIC, TA, pH) measured with specific methods (NDIR, Gran titration).
• Provides temporal and spatial context: data from a specific cruise (ORI-1086) in the East China Sea over 12 days in August 2014.
• Part of a documented long-term observation program by a research institution.

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 cruise.
