Trans Future 5 Cruise: Surface Ocean Carbon and Meteorological Data

Surface underway data from the research vessel Trans Future 5 tracks atmospheric and oceanic carbon dioxide across the Bass Strait, Coral Sea, North Pacific Ocean, Philippine Sea, Solomon Sea, South Pacific Ocean, and Tasman Sea. Collected between June 27 and December 9, 2006, the dataset includes measurements of air and sea partial pressure of CO2, sea surface temperature, salinity, wind speed, and solar radiation. These observations support the study of air-sea gas exchange and ocean carbon uptake in the western Pacific region.

Use Cases

• Calculating air-sea CO2 flux based on the partial pressure difference between the atmosphere and water.
• Analyzing correlations between sea surface temperature and oceanic carbon dioxide concentrations.
• Studying regional carbon sink variability in the western Pacific using time-series underway data.
• Validating ocean carbon models with in-situ measurements of salinity and sea surface temperature.
• Investigating the influence of meteorological conditions like wind speed and solar radiation on gas exchange.

Strengths

• Covers a wide geographic area spanning seven distinct ocean regions and seas.
• Includes directly measured, co-located atmospheric and oceanic carbon dioxide parameters.
• Specifies the precise instruments used, including a CO2 gas analyzer and thermosalinographs.

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable across all sources.
• The dataset's last update date conflicts between sources (2006-12-09 vs. 2026-03-05), creating uncertainty about its maintenance status.
• Data license information is not provided, which may restrict reuse.
