CLIVAR P14 2007: Underway Ocean Carbon and Meteorological Data from MIRAI

Bering Sea, North Pacific, and South Pacific Ocean surface data were collected by the R/V MIRAI from October to December 2007. The dataset includes measurements of air and water carbon dioxide partial pressure, salinity, sea surface temperature, and wind conditions. It was collected as part of the international CLIVAR repeat hydrography program to quantify changes in ocean carbon storage and transport.

Use Cases

• Quantifying air-sea CO2 flux based on simultaneous atmospheric and water pCO2 measurements.
• Analyzing correlations between sea surface temperature, salinity, and carbon dioxide fugacity.
• Validating regional ocean carbon models using in-situ underway observational data.
• Studying seasonal meteorological conditions (wind, air pressure, temperature) over the Pacific Ocean.

Strengths

• Data covers a specific, well-documented research cruise (CLIVAR P14) with two associated cruise IDs (49NZ20071008, 49NZ20071122).
• Includes directly measured chemical (CO2), physical (SST, salinity), and meteorological (wind, air temp) parameters from calibrated instruments.
• Cross-platform presence (Data.gov, NASA Earthdata) indicates formal archival and importance for the ocean carbon community.

Limitations

• Key metadata is missing: row count, file size, specific column names, and license information are not provided.
• Conflicting 'last updated' dates (2007-12-26 vs. 2026-03-05) create uncertainty about metadata maintenance.
• Dataset is from a single, time-bound cruise, limiting temporal and spatial scope for long-term trend analysis.
