PACIFICA_49RY20070606 data includes ALKALINITY, DISSOLVED INORGANIC CARBON, CHLOROFLUOROCARBONS, NITRATE, and 18 other variables collected from the Ryofu Maru II in the North and South Pacific Ocean from June 6 to July 24, 2007. These discrete sample and profile observations were made using CTD, Coulometer, and bottle instruments. The data were collected by Masahiko Fujimura of the Japan Meteorological Agency and Masao Ishii of the Meteorological Research Institute as part of the PACIFICA international collaborative project for Pacific Ocean interior carbon synthesis.
Use Cases
- Modeling ocean acidification based on pH and alkalinity measurements.
- Studying carbon sequestration based on dissolved inorganic carbon (DIC) and delta carbon-13 data.
- Analyzing nutrient cycles based on nitrate, phosphate, and silicate concentrations.
- Investigating chlorofluorocarbon (CFC) tracer distribution for ocean circulation studies.
- Calibrating biogeochemical models based on chlorophyll a and phaeopigment profiles.
Strengths
- Data covers 18+ distinct chemical, biological, and physical parameters relevant to ocean carbon studies.
- Observations span a specific 49-day cruise in the North and South Pacific Ocean in 2007.
- Data collection involved standardized instruments like CTD and Coulometer for DIC measurement.
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 2007 cruise.
