PACIFICA_49EW19981003 collected discrete chemical and physical measurements from the North Pacific Ocean in October 1998. Nobuo Tsurushima of the Advanced Industrial Science and Technology gathered data on dissolved inorganic carbon, alkalinity, nutrients, and temperature using CTD and bottle instruments. This dataset is part of the PACIFICA project, an international synthesis effort for Pacific Ocean interior carbon data supported by PICES.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Analyzing nutrient cycling relationships based on nitrate, phosphate, and silicate concentrations.
- Studying water column structure and properties based on temperature, salinity, and hydrostatic pressure profiles.
- Calibrating regional carbon models based on alkalinity and dissolved oxygen data.
Strengths
- Includes multiple key ocean carbon cycle parameters: dissolved inorganic carbon, alkalinity, pH, and nutrients.
- Data collected during a specific research cruise (PACIFICA_49EW19981003) providing a coherent snapshot.
- Part of a larger international collaborative project (PACIFICA) for data synthesis.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1998-10-20; freshness should be verified for contemporary applications.
- Row count is unknown, which may limit suitability assessment for large-scale analyses.
