PACIFICA_49HO19990601 data set includes chemical and physical measurements from the North Pacific Ocean collected during cruise HO99-1 from June 1 to June 15, 1999. Shuichi Watanabe of Hokkaido University collected these data using CTD and Coulometer instruments. The data include alkalinity, dissolved inorganic carbon, pH, salinity, and water temperature.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements
- Analyzing nutrient cycles based on nitrate, phosphate, and silicate data
- Studying water column properties based on temperature, salinity, and hydrostatic pressure profiles
- Calibrating biogeochemical models based on alkalinity and ammonium data
Strengths
- Data collected over a specific 15-day period in June 1999
- Includes 12 measured variables including key carbon cycle parameters
- Part of the international PACIFICA project for Pacific Ocean interior carbon synthesis
Limitations
- Last updated 1999-06-15 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
