VOS James Clark Ross 2006: Ocean Carbon and Surface Properties

NCEI Accession 0157244 contains surface underway chemical and physical data from the R/V James Clark Ross cruise 74JC20061024 in the South Atlantic and Southern Oceans. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, salinity, and sea surface temperature, collected using CO2 gas analyzers and thermosalinographs. Data were contributed by researchers from CSIRO, Plymouth Marine Laboratory, and the University of East Anglia.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure difference measurements.
• Analyzing ocean acidification trends in the Southern Ocean using in-situ pCO2 data.
• Correlating sea surface temperature and salinity with carbon dioxide concentrations.
• Validating satellite-derived ocean carbon models with high-resolution underway observations.

Strengths

• Data has a precise temporal coverage from 2006-10-24 to 2006-12-01.
• Includes direct measurements of key carbon cycle variables (pCO2 in air and water).
• Cross-platform presence on NASA Earthdata and Data.gov signals importance and accessibility.

Limitations

• Column names and exact data structure are not provided in any source.
• Conflicting 'last updated' dates (2006-12-01 vs. 2026-03-06) create uncertainty about metadata freshness.
• No information on data volume (rows, size) or license is available.
