North Pacific Ocean Carbon and Acidification Measurements from R/V Keifu Maru II, 2018

Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, and other seawater properties collected during a 2018 research cruise. The National Oceanic and Atmospheric Administration gathered this data in the North Pacific Ocean from July 9 to August 29, 2018. It is part of the Ocean Carbon and Acidification Data System (OCADS).

Use Cases

• Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements
• Assessing ocean acidification trends based on pH on the total scale
• Studying marine biogeochemical cycles based on nutrient and oxygen profiles
• Calibrating oceanographic sensors based on discrete temperature and salinity data

Strengths

• Data covers a specific 52-day research cruise in 2018, providing a temporal snapshot.
• Includes multiple co-located chemical and physical parameters (DIC, alkalinity, pH, temperature, salinity, oxygen, nutrients).
• Collected by the authoritative 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.
