Trans Future 5 Ship-Based Ocean Carbon and Meteorological Measurements

Surface underway data from the vessel Trans Future 5 provides measurements of carbon dioxide partial pressure in air and water, alongside meteorological and physical oceanographic variables. The dataset covers 24 distinct cruises across the western Pacific Ocean and adjacent seas from January 2014 to July 2015. Measurements include air and sea temperature, barometric pressure, relative humidity, salinity, wind speed, and incoming solar radiation.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differences.
• Analyzing seasonal variability of surface ocean pCO2 across multiple ocean basins.
• Validating satellite-derived sea surface temperature and salinity products with in-situ ship data.
• Studying the relationship between meteorological conditions (wind speed, solar radiation) and ocean carbon parameters.

Strengths

• Data collection spans 24 distinct cruise legs over an 18-month period, providing temporal coverage.
• Includes direct, co-located measurements of atmospheric and aquatic carbon dioxide partial pressure, enabling flux calculations.
• Covers a wide geographic area across nine distinct seas and straits in the Pacific region.

Limitations

• Key metadata such as row count, file size, and specific column names are not provided on any platform.
• Conflicting last-updated dates (2015-07-15 vs. 2026-03-05) create uncertainty about data currency and versioning.
• License information is absent, which may restrict clear understanding of permissible use.
