SOIREE: Ocean Carbon and Meteorology from RV Tangaroa Cruise

From February 2 to 28, 1999, this dataset contains surface underway measurements collected from the RV Tangaroa during the SOIREE experiment. It includes measurements of the partial pressure of carbon dioxide in air and water, sea surface temperature, salinity, barometric pressure, and wind speed across the Indian Ocean, South Pacific Ocean, Southern Oceans, and Tasman Sea. The data were collected using a Carbon dioxide (CO2) gas analyzer and support research on air-sea gas exchange.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differences.
• Analyzing correlations between sea surface temperature and carbon dioxide fugacity.
• Validating ocean carbon cycle models with in-situ underway measurements.
• Studying spatial variability of surface ocean properties during a specific research cruise.

Strengths

• Provides coordinated measurements of atmospheric and aquatic CO2 partial pressure, enabling direct flux calculations.
• Covers a specific, well-documented scientific experiment (SOIREE) with a clear time range of February 1999.
• Includes multiple concurrent physical and chemical variables (salinity, SST, wind speed) for contextual analysis.

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable across all sources.
• The dataset's license information is not provided, restricting clarity on reuse terms.
• Data is limited to a single month from a single vessel, constraining temporal and spatial generalizability.
