July-August 1998 chemical and physical measurements from the North Pacific Ocean collected during cruise HO98-3 on the Hokusei Maru. The data include dissolved inorganic carbon, alkalinity, pH, nutrients, salinity, and temperature, gathered using CTD and Coulometer instruments. These observations were collected by Shuichi Watanabe of Hokkaido University as part of the PACIFICA international carbon synthesis project.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Analyzing nutrient distributions in the North Pacific based on ammonium, nitrate, nitrite, phosphate, and silicate data.
- Studying the relationship between physical properties and carbon chemistry based on concurrent temperature, salinity, and hydrostatic pressure profiles.
- Calibrating regional carbon cycle models based on discrete sample data for alkalinity and dissolved oxygen.
Strengths
- Data covers a specific one-month cruise (1998-07-18 to 1998-08-18) providing a focused temporal snapshot.
- Includes multiple related chemical and physical parameters (12 variables) for integrated analysis.
- Part of the PACIFICA international project, suggesting standardized collection methods.
Limitations
- Last updated 1998-08-18 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.
