NCEI Accession 0157275 contains surface underway chemical and physical data collected aboard the JAMES CLARK ROSS research vessel in the South Atlantic and Southern Oceans from March 11 to April 17, 2009. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, salinity, and sea surface temperature, collected using carbon dioxide gas analyzers and thermosalinographs. Data were collected by researchers from Plymouth Marine Laboratory and the University of East Anglia as part of the VOS_James_C_Ross_2009 dataset.
Use Cases
- Modeling air-sea carbon dioxide exchange based on partial pressure measurements.
- Analyzing ocean surface chemistry variability based on salinity and temperature data.
- Studying seasonal carbon cycling in high-latitude Southern Oceans based on the described time-series measurements.
- Calibrating satellite-derived ocean carbon data using in-situ surface measurements.
Strengths
- Data covers a specific 38-day research cruise in the Southern Oceans.
- Includes directly measured chemical variables like partial pressure of CO2 in both air and water.
- Collected by named researchers from recognized marine research institutions.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2009-04-17 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
