South Pacific Ocean Halocarbon and Carbon Dioxide Measurements from 1991 Cruise

July-August 1991 measurements of oceanic halocarbons and carbon dioxide collected during the WOCE P16S research cruise. Data includes CFC measurements via electron capture gas chromatography and CO2 measurements by multiple research groups. The cruise covered the South Pacific Ocean from +4S to +38S latitude and +137W to +151W longitude.

Use Cases

• Analyze temporal trends of CFC concentrations in the South Pacific Ocean during July-August 1991.
• Correlate oceanic carbon dioxide measurements with spatial coordinates (+4S to +38S, +137W to +151W).
• Study the distribution of halocarbons relative to cruise track and sampling depth.
• Validate ocean carbon cycle models using in-situ CO2 measurements from multiple research groups.

Strengths

• Data collected during a defined 41-day cruise from July 16 to August 25, 1991.
• Spatial coverage spans a 34-degree latitude and 14-degree longitude range in the South Pacific.
• Multiple measurement groups contributed data, including for CFCs and CO2.

Limitations

• Dataset is over 30 years old, limiting analysis of recent ocean conditions.
• Sample size and row count are unknown, making statistical significance unclear.
• Geographic coverage is limited to a single cruise track in the South Pacific.
