PACIFICA project data includes dissolved inorganic carbon, alkalinity, pH, and nutrient measurements from the North Pacific Ocean. Collected by Shuichi Watanabe of Hokkaido University aboard the Hokusei Maru during cruise HO97-1 from June 20 to July 5, 1992. The dataset likely contains discrete sample and profile observations for parameters like ammonium, nitrate, phosphate, silicate, dissolved oxygen, salinity, and temperature.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Studying nutrient cycling in marine ecosystems based on ammonium, nitrate, phosphate, and silicate data.
- Analyzing carbon system parameters for climate research based on alkalinity and dissolved inorganic carbon.
- Investigating physical oceanographic conditions based on concurrent salinity and temperature profiles.
Strengths
- Data covers 12 key chemical and physical ocean parameters, including ALKALINITY, DISSOLVED INORGANIC CARBON, and NITRATE.
- Observations were collected during a specific research cruise (HO97-1/PACIFICA_49HO19970602) over a defined 16-day period in 1992.
- Project was an international collaborative effort supported by the North Pacific Marine Science Organization (PICES).
Limitations
- Last updated 1992-07-05 00:00:00; freshness should be verified.
- Row count and column-level documentation are absent; field semantics must be inferred after download.
