Umitaka-Maru Cruises: Ocean Carbon Measurements

Surface underway measurements from the TR/V Umitaka-Maru cruises cover a period from 2006-01-04 to 2009-02-04. The dataset likely contains partial pressure of carbon dioxide in water and atmosphere, sea surface temperature, salinity, and barometric pressure. These variables are collected in the Indian and Southern Ocean.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements.
• Analyzing ocean acidification trends from pCO2 and salinity data.
• Correlating sea surface temperature with carbon dioxide concentrations.
• Studying regional variability in the Southern Ocean from underway cruise data.

Strengths

• Data covers a multi-year time range from 2006 to 2009.
• Measurements are from specific research vessel cruises (TR/V Umitaka-Maru).
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov).

Limitations

• Column names and exact row count are unknown.
• License information is not provided.
• There is a conflict in the 'last updated' metadata between sources.
