NCEI Accession 0156927 includes surface underway chemical, meteorological, and physical data collected from the RYOFU MARU research vessel across the Bismarck Sea, East China Sea, Japan Sea, North Pacific Ocean, Philippine Sea, and South Pacific Ocean from 1989-11-17 to 1995-03-07. The dataset contains measurements of BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide in the atmosphere and water, SALINITY, and SEA SURFACE TEMPERATURE. These data were collected by Shu Saito of the Japan Meteorological Agency using a Carbon dioxide (CO2) gas analyzer.
Use Cases
- Modeling air-sea carbon dioxide flux based on partial pressure measurements in the atmosphere and water.
- Analyzing correlations between sea surface temperature and carbon dioxide solubility as described in the dataset.
- Studying regional variability in ocean carbon chemistry across the listed sea basins.
- Calibrating or validating larger-scale ocean carbon models with in-situ surface underway data.
Strengths
- Data collection spans over five years, from 1989-11-17 to 1995-03-07.
- Covers multiple distinct sea regions including the Bismarck Sea, East China Sea, and North Pacific Ocean.
- Includes directly measured variables for both atmospheric and aquatic carbon dioxide partial pressure.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1995-03-07; freshness should be verified.
