NCEI Accession 0081005 contains surface underway chemical, meteorological, optical, and physical data collected from the R/V Marion Dufresne in the Indian Ocean and Southern Oceans south of 60 degrees South. The data include measurements of barometric pressure, fluorescence, partial pressure of carbon dioxide in air and water, salinity, and sea surface temperature from January to August 2000. These data were collected by Nicolas Metzl of the Universite Pierre et Marie Curie as part of the OISO-4 and OISO-5 dataset series.
Use Cases
- Modeling ocean-atmosphere carbon dioxide exchange based on partial pressure measurements.
- Analyzing sea surface temperature and salinity relationships in the Southern Ocean.
- Studying temporal trends in surface ocean carbon chemistry during the austral summer.
- Validating satellite-derived ocean carbon data with in-situ surface measurements.
Strengths
- Data collection spans a 7-month period from January to August 2000.
- Includes multiple related variables: carbon dioxide partial pressure in air and water, salinity, temperature, barometric pressure, and fluorescence.
- Geographic coverage focuses on the Southern Ocean south of 60 degrees South, a critical region for climate studies.
Limitations
- Last updated 2000-08-14 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.
