Surface underway data from the research vessel Trans Future 5 tracks carbon dioxide exchange between the ocean and atmosphere across the Pacific Ocean and adjacent seas from 2009-01-03 to 2010-01-05. Yukihiro Nojiri of the National Institute for Environmental Studies collected these chemical, meteorological, and physical observations. The dataset includes measurements of partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, wind speed, and solar radiation.
Use Cases
- Modeling air-sea carbon dioxide flux based on partial pressure differentials mentioned in the description.
- Analyzing correlations between sea surface temperature and carbon dioxide solubility described in the data.
- Studying regional variability in ocean carbon chemistry across the described Pacific Ocean basins.
- Validating satellite-derived salinity or sea surface temperature products using in-situ measurements from the voyage.
Strengths
- Data covers a specific year-long voyage across multiple ocean basins, providing a continuous transect.
- Includes co-located measurements for key carbon cycle variables like CO2 partial pressure, salinity, and temperature.
- Collected by a named principal investigator from a national environmental research institute.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2010-01-05 00:00:00; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
