PACIFICA: Ocean Carbon and Chemistry Profiles from the Pacific Ocean, 1999

PACIFICA_49NZ19991121 includes biological, chemical, and physical data from discrete sample and CTD profile observations in the North and South Pacific Ocean. The data were collected aboard the MIRAI research vessel from November 21 to December 27, 1999, by researchers from JAMSTEC and the Meteorological Research Institute. Measurements include dissolved inorganic carbon, oxygen, nutrients, chlorophyll, temperature, and salinity.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon (DIC) and pH measurements.
• Analyzing nutrient cycling and primary productivity based on nitrate, phosphate, silicate, and chlorophyll data.
• Studying water mass properties and ocean circulation using CTD-derived temperature, salinity, and density (SIGMA-T) profiles.
• Calibrating and validating satellite ocean color algorithms using in-situ chlorophyll and fluorescence data.

Strengths

• Data includes multiple related parameter groups (biological, chemical, physical, optical) for a holistic view.
• Observations were collected during a defined research cruise (MR98-K07) over a 37-day period in 1999.
• Project is part of the international PACIFICA synthesis effort supported by PICES.

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 modeling.
• Data may reflect temporal bias from a single cruise in late 1999.
