Chemical and physical profile data collected from the OSHORO MARU research vessel in the North Pacific Ocean from 1993-06-11 to 1993-06-20. The data include dissolved inorganic carbon, alkalinity, pH, salinity, water temperature, and nutrients like nitrate and phosphate. These data were collected by Shuichi Watanabe of Hokkaido University as part of the PACIFICA project, an international synthesis effort for Pacific Ocean interior carbon.
Use Cases
- Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements.
- Studying nutrient cycling in the North Pacific based on nitrate, phosphate, and silicate data.
- Calibrating satellite-derived sea surface salinity and temperature products based on in-situ CTD profile data.
- Analyzing carbonate system parameters for climate studies based on alkalinity and dissolved inorganic carbon.
Strengths
- Includes 12 measured variables relevant to ocean carbon cycling and acidification.
- Data collected over a defined 10-day period in June 1993, providing a temporal snapshot.
- Part of the PACIFICA international synthesis project, suggesting standardized collection protocols.
Limitations
- Last updated 1993-06-20 00:00:00; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
