Pacific Ocean Ship pCO2, Salinity, and Meteorological Measurements 2019-2020

Surface underway data from the M/S Trans Future 5 captures the air-sea exchange of carbon dioxide across five Pacific Ocean basins. Measurements include the partial pressure of CO2 in both air and water, alongside sea surface salinity, temperature, and wind parameters. This dataset supports the quantification of oceanic carbon uptake and its relationship with surface conditions.

Use Cases

• Calculating air-sea CO2 flux based on measured pCO2 difference and wind speed.
• Analyzing correlations between sea surface temperature and pCO2 levels in different ocean basins.
• Validating satellite-derived sea surface salinity and temperature products with in-situ thermosalinograph data.
• Modeling regional carbon budgets in the North Pacific, Philippine, Solomon, South Pacific, and Tasman Seas.

Strengths

• Data collection spans nearly a full year, from 2019-01-13 to 2020-01-07, providing seasonal coverage.
• Includes direct measurements of both atmospheric and aquatic pCO2, enabling flux calculations.
• Instruments are explicitly named, including a CO2 gas analyzer and thermosalinographs, clarifying the measurement methodology.

Limitations

• Key metadata is missing or conflicting: row count, file size, and license are not provided by any source.
• The dataset's last update date is inconsistent, reported as both 2020-01-07 and 2026-03-05.
• Column names are not listed, requiring inference from the description for analysis.
