PACIFICA_49SU19990830 includes discrete measurements of dissolved inorganic carbon, pH, alkalinity, chlorofluorocarbons, and nutrients collected from the SHUMPU MARU in the Philippine Sea. The data were collected by researchers from the Japan Meteorological Agency and Meteorological Research Institute during a cruise from August 30 to September 6, 1999. 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 historical chlorofluorocarbon (CFC-11, CFC-12) distributions as ocean tracers
- Studying nutrient cycling (nitrate, phosphate, silicate) in the Philippine Sea
- Calibrating biogeochemical models using concurrent measurements of alkalinity and temperature
Strengths
- Includes over 20 measured variables, including key carbon cycle parameters (DIC, alkalinity, pH) and nutrients
- Data collected during a dedicated research cruise (PACIFICA_49SU19990830) with specific instruments (CTD, Coulometer)
- Part of an international collaborative project (PACIFICA) for data synthesis
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
