Surface underway data collected from the Hakuho Maru research vessel during a voyage from 2009-12-16 to 2010-01-26. The dataset includes measurements of partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure from the Indian Ocean, South Atlantic Ocean, and Southern Oceans. Data were collected by Daisuke Sasano of the Meteorological Research Institute and submitted to NOAA NCEI.
Use Cases
- Modeling air-sea carbon dioxide flux based on partial pressure measurements in the atmosphere and water.
- Analyzing the relationship between sea surface temperature and carbon dioxide solubility mentioned in the description.
- Studying oceanographic conditions in the Southern Oceans based on salinity and temperature data.
- Calibrating or validating satellite-derived sea surface carbon dioxide estimates using in-situ measurements.
Strengths
- Data covers a specific 42-day research voyage with a defined spatial scope across three major ocean basins.
- Includes key variables for carbon cycle studies: partial pressure of CO2 in both air and water, salinity, and temperature.
- Originates from a recognized research institution (Meteorological Research Institute) and is archived at NOAA NCEI.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2010-01-26; freshness should be verified for contemporary climate studies.
- Row count is unknown, which may limit suitability assessment for large-scale statistical modeling.
