CLIVAR P06: Underway Ocean Carbon and Meteorology from R/V Mirai

From August to October 2003, this dataset contains surface underway measurements of carbon dioxide partial pressure, salinity, temperature, and wind collected aboard the R/V Mirai in the Coral Sea, South Pacific Ocean, and Tasman Sea. It was collected by Akihiko Murata of JAMSTEC as part of the CLIVAR P06/BEAGLE 2003 program to quantify changes in ocean carbon storage and transport. The data likely includes time-series records from a carbon dioxide gas analyzer and a shower head chamber equilibrator.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in air and water.
• Analyzing correlations between sea surface temperature, salinity, and oceanic pCO2.
• Studying synoptic-scale meteorological conditions (wind speed/direction, air pressure) over the ocean.
• Validating and calibrating models of ocean carbon uptake in the South Pacific region.

Strengths

• Data collected as part of the systematic, international CLIVAR Global Ocean Carbon and Repeat Hydrography Program.
• Includes directly measured, concurrent atmospheric and oceanic carbon dioxide partial pressures.
• Covers a specific, well-documented research cruise (BEAGLE 2003) with known vessel (MIRAI) and principal investigator.

Limitations

• Key metadata conflicts: the listed author's affiliation is given as both JAMSTEC and the Meteorological Research Institute.
• Critical technical details are missing: column names, row counts, file size, and license are unknown.
• The dataset's freshness is unclear; metadata was updated in 2026, but the underlying data is from 2003.
