Discrete sample and profile data collected from the HAKUREI MARU vessel in the North Pacific Ocean and Philippine Sea between August and October 1998. The dataset includes measurements of dissolved inorganic carbon, pH, alkalinity, chlorofluorocarbons, dissolved oxygen, nutrients, and water temperature. Data were collected by researchers from General Environmental Technos Co LTD and the National Institute for Resources and Environment as part of the PACIFICA project.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing historical chlorofluorocarbon (CFC) distributions as tracers of ocean circulation.
- Studying nutrient dynamics in the Pacific Ocean based on nitrate, phosphate, and silicate content.
- Investigating relationships between physical parameters like temperature and salinity and chemical parameters like pH.
Strengths
- Includes 18 distinct chemical, biological, and physical parameters, providing a multi-faceted view of ocean conditions.
- Data collected over a focused 2-month cruise in 1998, offering a snapshot of late-20th-century Pacific Ocean chemistry.
- Part of the international PACIFICA synthesis project, suggesting standardized collection methods.
Limitations
- Last updated 1998-10-21 00:00:00; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
