The Philippine Sea is the geographic scope for this dataset of discrete sample and profile observations collected from the SHUMPU MARU between 1998-04-22 and 1998-04-30. It includes measurements for dissolved inorganic carbon, pH, alkalinity, temperature, salinity, nutrients, and chlorophyll a, collected using CTD and bottle instruments. These data were gathered by researchers from the Japan Meteorological Agency and Meteorological Research Institute as part of the international PACIFICA project for synthesizing Pacific Ocean interior carbon data.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Studying marine primary productivity based on chlorophyll a and nutrient concentration data.
- Analyzing water mass properties and circulation based on salinity, temperature, and hydrostatic pressure profiles.
- Calibrating satellite-derived ocean color data with in-situ chlorophyll a measurements.
Strengths
- Includes over 20 measured variables covering biological, chemical, and physical oceanographic parameters.
- Data collection is temporally focused on a specific cruise from 1998-04-22 to 1998-04-30.
- Part of the international PACIFICA project, suggesting standardized collection protocols.
Limitations
- Last updated 1998-04-30 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.
