PACIFICA_49OS20030311 includes chemical and physical data collected from the OSHORO MARU in the North Pacific Ocean from March 11 to March 20, 2003. Shuichi Watanabe of JAMSTEC; Mutsu Institute for Oceanography collected these data during cruise OS133-KNOT using CTD, Coulometer, and bottle instruments. The dataset contains measurements for alkalinity, dissolved inorganic carbon, pH, nutrients, and other oceanographic variables.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements
- Analyzing nutrient distributions and their relationship to carbon chemistry based on nitrate, phosphate, and silicate data
- Studying the physical drivers of chemical profiles based on concurrent temperature, salinity, and hydrostatic pressure data
Strengths
- Data collected over a 10-day period in March 2003, providing a temporal snapshot
- Includes 12 measured variables covering chemical, physical, and nutrient parameters
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
