June-July 2004 data from the Ryofu Maru II research vessel in the North Pacific Ocean. The dataset includes discrete sample and profile measurements of dissolved inorganic carbon, pH, alkalinity, temperature, salinity, nutrients, and chlorofluorocarbons. It was collected by Kazuhiro Nemoto and Masao Ishii as part of the PACIFICA international synthesis project.
Use Cases
- Modeling ocean acidification impacts based on pH and alkalinity measurements
- Analyzing carbon sequestration dynamics based on dissolved inorganic carbon and chlorofluorocarbon data
- Studying marine nutrient cycles based on nitrate, phosphate, and silicate concentrations
- Calibrating biogeochemical models based on hydrostatic pressure and temperature profiles
Strengths
- Data covers a specific 26-day cruise in June-July 2004, providing a temporal snapshot
- Includes over 20 distinct chemical and physical parameters, such as ALKALINITY, DISSOLVED INORGANIC CARBON, and CHLOROFLUOROCARBONS
- Part of the PACIFICA international synthesis project, suggesting standardized collection methods
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 bias inherent to a single cruise track in the North Pacific Ocean
