Sea of Japan and North Pacific Ocean Carbon Chemistry Profiles from 2016

Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, and other seawater properties were collected during the R/V Ryofu Maru III cruise rf201608. The dataset covers the Sea of Japan and North Pacific Ocean from October 21 to December 6, 2016. It was contributed by the National Oceanic and Atmospheric Administration to the Ocean Carbon and Acidification Data System.

Use Cases

• Modeling ocean acidification dynamics based on dissolved inorganic carbon and pH measurements.
• Analyzing regional carbon budgets based on discrete profile data from the Sea of Japan.
• Studying marine nutrient cycles based on nutrient concentration data.
• Calibrating oceanographic sensors based on concurrent temperature, salinity, and oxygen profiles.

Strengths

• Measurements include multiple key ocean carbon system variables: DIC, total alkalinity, and pH on the total scale.
• Data has a defined temporal coverage from 2016-10-21 to 2016-12-06.
• Spatial coverage includes two distinct ocean basins: the Sea of Japan and the North Pacific.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single research cruise.
