VOS_GOSars_2012: Ocean Carbon and Meteorological Measurements

From February to August 2012, this dataset contains surface underway measurements of carbon dioxide fugacity, salinity, temperature, and other variables from the G.O. SARS research vessel in the North Atlantic Ocean, North Greenland Sea, North Sea, and Norwegian Sea. It also includes a smaller, related dataset from the KNORR vessel in the North Atlantic during June-July 2011. The data were collected using carbon dioxide gas analyzers and equilibrators, supporting research on ocean-atmosphere carbon exchange.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in water and atmosphere.
• Analyzing correlations between sea surface temperature, salinity, and dissolved oxygen concentrations.
• Studying regional meteorological conditions using wind speed, direction, air temperature, and relative humidity data.
• Validating ocean carbon cycle models with high-resolution surface underway observations.

Strengths

• Contains direct, instrument-measured variables including carbon dioxide fugacity, a key parameter for flux calculations.
• Covers a multi-month time series from February to August 2012 across several ecologically significant seas.
• Data is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating curation and importance.

Limitations

• Column names and precise data structure are not provided in any source, hindering immediate analysis.
• Conflicting 'last updated' dates (2012-08-13 vs. 2026-03-05) suggest potential metadata inconsistency across entries.
• The related 2011 KNORR dataset is described separately with incomplete metadata linkage.
