PACIFICA Ocean Carbon and Chemistry Profiles from the North Pacific, 2007

PACIFICA_49RY20070724 data includes dissolved inorganic carbon, pH, alkalinity, temperature, salinity, and related biological and chemical variables. The data were collected from discrete sample and profile observations aboard the Ryofu Maru II in the North Pacific Ocean and Philippine Sea between July 24 and October 8, 2007. Masahiko Fujimura of the Japan Meteorological Agency and Masao Ishii of the Meteorological Research Institute collected the data as part of the PACIFICA international collaborative project.

Use Cases

• Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
• Analyzing nutrient cycles and primary productivity based on nitrate, phosphate, silicate, and chlorophyll a data.
• Studying water mass properties and circulation using temperature, salinity, and hydrostatic pressure profiles.
• Investigating anthropogenic tracer distribution from Chlorofluorocarbon (CFC-11 and CFC-12) measurements.

Strengths

• Includes over 20 distinct chemical, biological, and physical parameters for a multi-faceted analysis.
• Data collected during a defined research cruise (PACIFICA_49RY20070724) from July to October 2007, providing temporal specificity.
• Originates from an international collaborative project (PACIFICA) supported by PICES, suggesting a standardized collection framework.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic and temporal bias inherent to a single vessel cruise in the North Pacific.
