Southern Ocean Surface Carbon Dioxide and Temperature Measurements, 2002

From March to December 2002, surface underway data was collected from the R/V Laurence M. Gould in the South Atlantic, South Pacific, and Southern Oceans. The dataset includes measurements of partial pressure of carbon dioxide in water, salinity, sea surface temperature, and barometric pressure. It was collected by researchers from Lamont-Doherty Earth Observatory and NOAA ESRL as part of the VOS_LMG_Lines_2002 project.

Use Cases

• Modeling ocean carbon uptake based on partial pressure of CO2 and sea surface temperature.
• Analyzing seasonal variability of surface water chemistry in the Southern Ocean based on time-series data.
• Calibrating satellite-derived sea surface salinity products using in-situ salinity measurements.
• Studying correlations between barometric pressure and oceanic CO2 fugacity.

Strengths

• Data collected over a 9-month period in 2002, providing seasonal coverage.
• Includes four key oceanographic variables: CO2 fugacity, salinity, sea surface temperature, and barometric pressure.
• Associated with a specific, documented research cruise (ID: 33LG20020307).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Last updated 2026-03-05 22:24:35.498410; freshness should be verified as the underlying data is from 2002.
