SOYO-MARU Underway Ocean Carbon and Surface Data

NCEI Accession 0157371 contains surface underway measurements collected aboard the SOYO-MARU vessel across the North Pacific Ocean, Philippine Sea, and South Atlantic Ocean from April to November 2012. The dataset includes barometric pressure, sea surface temperature, salinity, and the partial pressure of carbon dioxide in water. Data were collected by researchers from the National Research Institute of Fisheries Science using a CO2 gas analyzer and a micro-porous membrane equilibrator.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements.
• Analyzing correlations between sea surface temperature and ocean carbon content.
• Validating regional ocean carbon models with in-situ salinity and temperature data.
• Studying seasonal variability of surface ocean parameters across multiple ocean basins.

Strengths

• Data originates from a recognized research institution (National Research Institute of Fisheries Science).
• Covers three distinct oceanographic regions over a seven-month period.
• Specifies the precise instruments used for data collection (CO2 gas analyzer, micro-porous membrane equilibrator).

Limitations

• Column names and data structure are not provided in the available metadata.
• Exact row count and file size are unknown.
• License information is not specified.
