Chemical and physical oceanographic data collected from the MIRAI research vessel in the North Pacific Ocean during May 1999. The dataset includes measurements of dissolved inorganic carbon, alkalinity, pH, nutrients, dissolved oxygen, salinity, and temperature. Data were collected by researchers from the Japan Agency for Marine-Earth Science and Technology as part of the PACIFICA international synthesis project.
Use Cases
- Modeling ocean acidification trends based on pH and alkalinity measurements.
- Analyzing carbon sequestration potential based on dissolved inorganic carbon concentrations.
- Studying nutrient cycles in the North Pacific based on ammonium, nitrate, phosphate, and silicate data.
- Calibrating ocean carbon models using co-located measurements of temperature, salinity, and pressure.
- Investigating dissolved oxygen levels for marine ecosystem health assessments.
Strengths
- Data includes multiple co-located chemical and physical parameters relevant for carbon cycle studies.
- Collection was part of an international collaborative project (PACIFICA) focused on data synthesis.
- Specific cruise (MR99-K02) and time period (1999-05-08 to 1999-05-30) are documented.
Limitations
- Last updated 1999-05-30 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
