From June 22 to July 6, 1999, chemical and physical profile data were collected from the Hokusei Maru in the North Pacific Ocean during cruise HO99-2. The data include alkalinity, dissolved inorganic carbon, dissolved oxygen, nutrients, salinity, temperature, and pH. These observations were collected by Shuichi Watanabe of Hokkaido University as part of the PACIFICA project.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing nutrient cycles in the North Pacific based on nitrate, phosphate, and silicate concentrations.
- Studying ocean acidification trends based on pH and carbonate system parameters.
- Correlating physical oceanographic conditions with chemical profiles based on temperature, salinity, and hydrostatic pressure.
Strengths
- Data covers a specific 15-day cruise in the North Pacific Ocean.
- Includes multiple related chemical parameters (carbon, nutrients, pH) and physical variables.
- Data originates from a defined international collaborative project (PACIFICA).
Limitations
- Last updated 1999-07-06 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.
