Surface Underway CO2 and Oceanographic Data from R/V Ryofu Maru III

From 2018-01-11 to 2019-09-22, this dataset contains surface underway measurements from research vessel cruises in the Pacific Ocean. It includes the partial pressure of carbon dioxide in water, barometric pressure, sea surface salinity, and sea surface temperature. Data were collected using a CO2 gas analyzer and a shower head chamber equilibrator.

Use Cases

• Estimating ocean carbon uptake based on partial pressure of CO2 measurements.
• Analyzing sea surface temperature and salinity correlations across the Pacific Ocean.
• Validating ocean carbon cycle models using underway time-series data.
• Studying seasonal variability in surface ocean chemistry from multi-year cruise data.

Strengths

• Data collection spans multiple years, covering 2018 and 2019.
• Includes direct measurements of key ocean carbon cycle variables like pCO2.
• Cross-platform presence on datagov and nasa_earthdata signals established curation.

Limitations

• Column names and exact data structure are not provided in any source.
• Sources conflict on the specific NCEI accession number and exact temporal endpoints for constituent datasets.
• Metadata on row count, file size, and license is consistently absent.
