Surface underway data collected from the S. A. AGULHAS research vessel in the Indian, South Atlantic, and Southern Oceans from 2009-01-26 to 2011-01-10. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure. Dr Pedro M.S. Monteiro of the Council for Scientific and Industrial Research collected these data as part of the VOS_Agulhas_Lines dataset.
Use Cases
- Modeling air-sea carbon dioxide flux based on the difference in partial pressure between the atmosphere and water.
- Analyzing ocean acidification trends in the Southern Ocean based on water carbon dioxide measurements.
- Studying the relationship between sea surface temperature and carbon dioxide solubility in surface waters.
- Calibrating or validating satellite-derived sea surface salinity products with in-situ measurements.
- Investigating seasonal or interannual variability of oceanic carbon parameters across multiple ocean basins.
Strengths
- Data covers a multi-year time series from 2009-01-26 to 2011-01-10.
- Measurements span three major ocean basins: Indian, South Atlantic, and Southern Oceans.
- Includes key variables for carbon cycle research: air-sea CO2 difference, salinity, and sea surface temperature.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2011-01-10 00:00:00; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
