CLIVAR I06S_2008: Underway Surface CO2 Measurements in the Indian and Southern Oceans

Underway measurements of surface partial pressure of carbon dioxide and related meteorological and physical oceanographic data collected during the R/V Roger Revelle CLIVAR cruise I06S_2008. The data were collected by Dr. Rik H. Wanninkhof of NOAA's Atlantic Oceanographic and Meteorological Laboratory from February 5 to March 14, 2008, in the Indian Ocean and Southern Oceans south of 60 degrees South. It includes measurements of air and sea temperature, salinity, barometric pressure, wind, fluorescence, and partial pressure of CO2 in both the atmosphere and water.

Use Cases

• Modeling air-sea CO2 flux based on the partial pressure difference measurements.
• Analyzing correlations between sea surface temperature, salinity, and CO2 concentrations.
• Studying seasonal or spatial variability of surface ocean carbon in the Southern Ocean.
• Calibrating or validating satellite-derived ocean carbon data products.

Strengths

• Data collection covers a specific, well-documented research cruise (EXPOCODE 33RR20080204) over a 38-day period.
• Includes multiple related variables (chemical, meteorological, optical, physical) for concurrent analysis.
• Collected by a named principal investigator from a recognized oceanographic laboratory (NOAA AOML).

Limitations

• Last updated 2008-03-14 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.
