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

Discrete water sample and profile data collected from the KEIFU MARU research vessel in the North Pacific Ocean and Philippine Sea between October 23 and December 8, 2007. The dataset includes measurements for dissolved inorganic carbon, pH, alkalinity, nutrients, chlorophyll, and related physical parameters like temperature and salinity. Data were collected by researchers from the Kobe Marine Observatory and Meteorological Research Institute as part of the international PACIFICA project for synthesizing Pacific Ocean interior carbon data.

Use Cases

• Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
• Studying nutrient cycling in ocean basins based on nitrate, phosphate, and silicate data.
• Analyzing biological productivity based on chlorophyll a and phaeopigment concentrations.
• Calibrating hydrographic models based on CTD-derived temperature, salinity, and pressure profiles.

Strengths

• Includes over 20 distinct chemical, biological, and physical parameters for a comprehensive water column characterization.
• Data collected during a dedicated research cruise (PACIFICA_49FA20071023) over a focused temporal range.
• Project was supported by the North Pacific Marine Science Organization (PICES), indicating a collaborative, scientific context.

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 is from a single cruise in 2007, limiting temporal analysis of trends.
