North Pacific Ocean Carbon and Water Chemistry Measurements from R/V Ryofu Maru III, 2013

North Pacific Ocean measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients collected from discrete samples and profiles during the R/V Ryofu Maru III cruise rf201304. The data were gathered by the National Oceanic and Atmospheric Administration from 2013-04-26 to 2013-05-27.

Use Cases

• Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
• Analyzing relationships between water chemistry and biological activity based on nutrient and oxygen data.
• Studying carbon sequestration in ocean waters based on total alkalinity and DIC profiles.
• Calibrating satellite-derived oceanographic data based on in-situ salinity and temperature profiles.

Strengths

• Includes multiple key ocean carbon system variables (DIC, total alkalinity, pH) for acidification studies.
• Data collected over a focused one-month cruise (2013-04-26 to 2013-05-27), providing temporal consistency.
• Originates from a recognized authority, the National Oceanic and Atmospheric Administration.

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 cruise in the North Pacific.
