GO-SHIP P13: Pacific Ocean Hydrographic and Carbon Chemistry Profiles from 2018

Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, chlorofluorocarbons, temperature, salinity, oxygen, and nutrients were collected during the R/V Ryofu Maru III cruise rf201806 in the Pacific Ocean. The data were gathered for GO-SHIP Section P13 from August 6 to September 27, 2018. The dataset is provided by the National Oceanic and Atmospheric Administration, Department of Commerce.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
• Tracing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12, CFC-113) concentrations.
• Assessing marine biogeochemical cycles and nutrient distributions from oxygen and nutrient profile data.
• Calibrating and validating oceanographic models with concurrent temperature, salinity, and chemical property profiles.

Strengths

• Includes a multi-parameter suite of chemical and physical oceanographic measurements from a single research cruise.
• Covers a specific transect (GO-SHIP Section P13) in the Pacific Ocean during a defined period from 2018-08-06 to 2018-09-27.
• Data provenance is clear, linked to a specific vessel (R/V Ryofu Maru III) and cruise (rf201806/EXPOCODE 49UP20180806).

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 analyses.
• Data may reflect geographic and temporal bias inherent to a single cruise in 2018.
