Discrete sample and profile data collected from the HAKUREI MARU in the North Pacific Ocean from 2000-09-12 to 2000-11-21. The dataset includes measurements of dissolved inorganic carbon, pH, alkalinity, chlorofluorocarbons, dissolved oxygen, nutrients, and water temperature. Data were collected by researchers from Kansai Environmental Engineering Center and Hokkaido University as part of the PACIFICA synthesis project.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements
- Analyzing nutrient cycling based on nitrate, nitrite, phosphate, and silicate concentrations
- Studying chlorofluorocarbon (CFC) and sulfur hexafluoride (SF6) tracer distributions for ocean ventilation research
- Calibrating biogeochemical models using concurrent profiles of temperature, salinity, and dissolved oxygen
Strengths
- Includes 18 distinct chemical and physical variables, such as CFCs, nutrients, and carbon parameters
- Data collected during a defined cruise period from 2000-09-12 to 2000-11-21
- Part of the international PACIFICA synthesis project supported by PICES
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
