Description
NCEI Accession 0157100 contains surface underway chemical, meteorological, and physical data collected by the research vessel MARION DUFRESNE across multiple seas and oceans from January 1991 to August 1993. The dataset includes measurements of the partial pressure of carbon dioxide, salinity, sea surface temperature, and barometric pressure, collected using a Carbon dioxide (CO2) gas analyzer. These data were collected by Alain Poisson of Universite Pierre et Marie Curie as part of the Minerve 07-28 cruise.
Use Cases
Modeling air-sea CO2 flux based on partial pressure of carbon dioxide measurements.
Analyzing ocean acidification trends based on surface water carbon chemistry data.
Studying regional variability in sea surface temperature and salinity across the Indian Ocean and Southern Ocean.
Calibrating satellite-derived oceanographic parameters with in-situ surface underway observations.
Strengths
Data spans over two and a half years, from 1991-01-05 to 1993-08-08.
Geographic coverage includes multiple major water bodies: the Arabian Sea, Bali Sea, Gulf of Aden, Red Sea, and Southern Oceans.
Includes key variables for carbon cycle studies: partial pressure of carbon dioxide, salinity, and sea surface temperature.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Last updated 1993-08-08; freshness should be verified for contemporary climate studies.
Row count is unknown, which may limit suitability assessment for large-scale machine learning tasks.
