North Pacific Ocean chemical and physical data collected from the MIRAI research vessel between September 4 and October 2, 2007. The dataset includes measurements of dissolved inorganic carbon, alkalinity, pH, nutrients, salinity, and temperature from discrete samples and CTD profiles. Data were collected by Makio Honda and Masahide Wakita of JAMSTEC as part of the PACIFICA international synthesis project.
Use Cases
- Modeling ocean acidification impacts based on pH and dissolved inorganic carbon measurements.
- Analyzing nutrient cycling in the North Pacific based on nitrate, phosphate, and silicate data.
- Studying relationships between physical and chemical ocean properties based on concurrent temperature, salinity, and oxygen measurements.
- Calibrating biogeochemical models using high-quality, discrete sample alkalinity and DIC data.
Strengths
- Data covers a specific 29-day research cruise (MR07-05) in the North Pacific Ocean.
- Includes 12 key chemical and physical parameters, such as ALKALINITY, DISSOLVED INORGANIC CARBON, and NITRATE.
- Supported by an international collaborative project (PACIFICA) under PICES, suggesting standardized collection.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
