PACIFICA (PACIFic ocean Interior CArbon) data includes dissolved inorganic carbon, temperature, salinity, nitrate, phosphate, and silicate measurements collected from discrete samples and CTD profiles. The data were gathered aboard the HOKKO MARU in the North Pacific Ocean from July 15 to July 25, 2006 by Tsuneo Ono of the National Research Institute of Fisheries Science. This dataset is part of an international collaborative project for synthesizing ocean interior carbon data in the Pacific Ocean.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon measurements
- Analyzing relationships between nutrient concentrations (nitrate, phosphate, silicate) and hydrographic conditions
- Studying water column properties and profiles based on CTD-derived temperature, salinity, and pressure data
Strengths
- Data covers a specific 10-day cruise in July 2006, providing a focused temporal snapshot
- Includes multiple key oceanographic parameters: carbon, nutrients, temperature, and salinity
- Collection involved discrete bottle samples and continuous CTD profiles, suggesting multiple measurement methods
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 geographic bias inherent to a single cruise track in the North Pacific
