Southern Ocean Carbon Dioxide and Halocarbon Measurements from 1992 WOCE Cruise

Measurements of oceanic carbon dioxide and chlorofluorocarbons (CFCs) were collected during the WOCE S04P research cruise in the Southern Ocean. The data was gathered by researchers Takahashi, Chapman, and Bullister over a 52-day expedition from February 14 to April 6, 1992.

Use Cases

• Analyze the relationship between oceanic carbon dioxide partial pressure and halocarbon concentrations across the sampled transect.
• Map the spatial distribution of CFC tracers within the -65S to -70S latitude and +70E to +162E longitude range to study water mass ventilation.
• Correlate measurement values with cruise track waypoints and timestamps to model temporal changes during the austral late summer.
• Use the paired carbon dioxide and CFC data points to calibrate or validate ocean carbon cycle models for the early 1990s.

Strengths

• Data covers a specific 52-day research cruise from Feb 14 to Apr 6, 1992.
• Geographic coverage is precisely defined from -65S to -70S latitude and +70E to +162E longitude.
• Includes two distinct but complementary chemical measurement types: carbon dioxide and halocarbons.

Limitations

• Sample size and row count are unknown, limiting statistical assessment.
• Data is from a single cruise in 1992, offering only a temporal snapshot.
• The specific measurement columns, units, and data structure are not provided.
