February 8 to March 15, 2016, this dataset contains surface underway measurements of carbon dioxide partial pressure, salinity, and sea surface temperature collected aboard the R/V Roger Revelle in the Indian and Southern Oceans. The data were collected by researchers from NOAA's Atlantic Oceanographic and Meteorological Laboratory using a carbon dioxide gas analyzer and other instruments. It is part of the SOCCOM_33RR20160208_UW dataset and archived under NCEI Accession 0157333.
Use Cases
- Calculate air-sea CO2 flux using the difference between water and atmospheric partial pressure of carbon dioxide (pCO2_water and pCO2_atmosphere) alongside barometric pressure and sea surface temperature.
- Analyze the relationship between seawater salinity and the partial pressure of carbon dioxide in water to study ocean mixing and carbon system dynamics.
- Model sea surface temperature as a driver for the spatial and temporal variability of pCO2_water across the cruise track in the Indian and Southern Oceans.
- Validate and calibrate satellite-derived sea surface temperature and salinity products using in-situ measurements from this research cruise.
Strengths
- Data covers a 36-day continuous research cruise in a critical region for climate (Southern Ocean).
- Includes simultaneous measurements of key variables: pCO2 in air and water, salinity, temperature, and barometric pressure for flux calculations.
- Collected and curated by authoritative NOAA and CDIAC ocean carbon research programs.
Limitations
- Limited temporal scope to a single cruise in early 2016, providing only a seasonal snapshot.
- Geographic coverage is restricted to the specific cruise track in the Indian and Southern Oceans.
- Sample size (number of rows/observations) and data resolution (temporal/spatial) are not specified in the provided information.
