Surface underway observations of atmospheric and oceanic carbon dioxide partial pressure, salinity, and temperature collected from the Hakuho Maru research vessel. The data were gathered in the Indian Ocean and Southern Oceans south of 60 degrees South by the Meteorological Research Institute between December 17, 2010, and January 17, 2011. Instruments included a barometric pressure sensor and a carbon dioxide gas analyzer.
Use Cases
- Calculate air-sea CO2 flux based on partial pressure measurements in water and atmosphere.
- Analyze the relationship between sea surface temperature and carbon dioxide fugacity mentioned in the description.
- Study spatial variability of surface ocean carbon chemistry in the Southern Ocean region.
- Validate or calibrate ocean carbon cycle models using in-situ underway observations.
Strengths
- Data includes simultaneous measurements of atmospheric and aquatic carbon dioxide partial pressure.
- Observations cover a specific research cruise over a one-month period in the Southern Ocean.
- Data collection involved specific instruments like a Carbon dioxide (CO2) gas analyzer.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2011-01-17 00:00:00; freshness should be verified.
