From November 1997 to January 1998, discrete sample and profile data were collected aboard the HAKUREI MARU in the North Pacific Ocean and Philippine Sea. The dataset includes measurements of dissolved inorganic carbon, pH, alkalinity, chlorofluorocarbons, dissolved oxygen, nutrients, and water temperature. It was 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
- Model ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
- Analyze historical chlorofluorocarbon (CFC) and sulfur hexafluoride (SF6) distributions as tracers of ocean ventilation.
- Study nutrient dynamics and primary productivity based on chlorophyll a, nitrate, phosphate, and silicate data.
- Assess water column structure and physical properties based on temperature, salinity, and hydrostatic pressure profiles.
Strengths
- Data covers a specific cruise period from 1997-11-10 to 1998-01-19.
- Includes a wide range of chemical, biological, and physical parameters relevant to ocean carbon studies.
- Part of the PACIFICA international collaborative project for Pacific Ocean interior carbon synthesis.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1998-01-19 00:00:00; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
