PACIFICA_49HO19970711 includes chemical, physical, and profile data collected from the Hokusei Maru in the North Pacific Ocean from July 11 to August 11, 1997. The data set contains measurements for alkalinity, ammonium, dissolved inorganic carbon, dissolved oxygen, nitrate, nitrite, phosphate, salinity, silicate, water temperature, and pH. These data were collected by Shuichi Watanabe of Hokkaido University as part of the PACIFICA international collaborative project.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Analyzing nutrient cycles based on nitrate, nitrite, phosphate, and silicate concentrations.
- Studying water column properties based on hydrostatic pressure, temperature, and salinity profiles.
- Investigating dissolved oxygen levels and their relationship to other chemical parameters.
Strengths
- Data covers a specific one-month cruise (1997-07-11 to 1997-08-11) in the North Pacific Ocean.
- Includes 12 measured variables, such as alkalinity, dissolved inorganic carbon, and multiple nutrients.
- Part of the PACIFICA international collaborative project for synthesizing Pacific Ocean interior carbon data.
Limitations
- Last updated 1997-08-11 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.
