North Pacific Ocean data collected from the MIRAI vessel during cruise CLIVAR_P01_2007 from July 24 to September 3, 2007. It includes discrete sample and profile measurements of dissolved inorganic carbon, alkalinity, pH, chlorofluorocarbons, nutrients, and other oceanographic variables. The data were collected by researchers from the Japan Agency for Marine-Earth Science and Technology and the Meteorological Research Institute as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.
Use Cases
- Quantifying changes in ocean carbon dioxide storage based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing ocean circulation and ventilation patterns based on chlorofluorocarbon (CFC-11, CFC-12, CFC-113) tracer data.
- Assessing nutrient distributions and biogeochemical cycles based on nitrate, phosphate, and silicate measurements.
- Calibrating and validating ocean carbon models based on comprehensive hydrographic profile data.
- Studying ocean acidification trends based on pH and total alkalinity data.
Strengths
- Data covers a specific research cruise (CLIVAR_P01_2007) over a defined period from 2007-07-24 to 2007-09-03.
- Includes a wide range of chemical and physical oceanographic variables, such as carbon isotopes, nutrients, and CFCs.
- Data collection involved specific instruments like an alkalinity titrator, CTD, and coulometer, suggesting methodological rigor.
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.
