SOOP Trans Future 5: Ocean-Atmosphere Carbon Flux Measurements

Surface underway data from the vessel Trans Future 5 provides measurements of carbon dioxide partial pressure and related variables across the western Pacific Ocean and adjacent seas from 2015-01-10 to 2016-01-11. The dataset includes air-sea difference calculations for carbon dioxide fugacity alongside standard meteorological and oceanographic parameters like salinity, sea surface temperature, and wind speed. These data were collected using specialized instruments including a carbon dioxide gas analyzer and thermosalinographs as part of the SOOP_Trans_Future_5_2015 lines project.

Use Cases

• Calculating ocean-atmosphere carbon dioxide flux based on air-sea difference measurements.
• Analyzing correlations between sea surface temperature and carbon dioxide partial pressure in water.
• Studying regional variability in marine meteorological conditions like absolute humidity and barometric pressure.
• Validating satellite-derived sea surface salinity or temperature products with in-situ underway measurements.

Strengths

• Covers a wide geographic area spanning nine distinct seas and straits in the Pacific region.
• Includes directly measured, co-located atmospheric and oceanic carbon dioxide parameters enabling flux calculations.
• Specifies the exact instruments used for data collection, including a shower head chamber equilibrator and thermosalinographs.

Limitations

• Column names and dataset size (rows, file size) are not provided by any source, limiting assessment of data structure and volume.
• Conflicting 'last updated' dates exist between platforms (2016-01-11 vs. 2026-03-05), casting doubt on metadata maintenance.
• License information is not specified for any platform source.
