PACIFICA_49HO19980601 includes chemical, physical, and profile data collected from the Hokusei Maru in the North Pacific Ocean from June 1 to June 15, 1998. The data were collected by Shuichi Watanabe of Hokkaido University using CTD, Coulometer, and bottle instruments. These measurements include alkalinity, dissolved inorganic carbon, dissolved oxygen, nitrate, nitrite, phosphate, silicate, salinity, temperature, and pH.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing nutrient distributions based on nitrate, nitrite, phosphate, and silicate content.
- Studying physical oceanographic properties based on hydrostatic pressure, salinity, and water temperature profiles.
- Investigating ocean acidification trends based on pH measurements over time.
Strengths
- Data originates from a specific research cruise (HO98-1/PACIFICA_49HO19980601) with documented instruments.
- Includes multiple related chemical and physical parameters for integrated analysis.
- Data collection is part of an international collaborative project (PACIFICA) supported by PICES.

- Last updated 1998-06-15 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.
