North Pacific Ocean and East China Sea Seawater Chemistry Profiles from 2016

Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, and nutrients collected during the R/V Keifu Maru II cruise ks201606. The dataset covers the North Pacific Ocean and East China Sea from June 18 to July 23, 2016, and is provided by the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling ocean acidification impacts based on dissolved inorganic carbon and pH measurements.
• Analyzing marine carbon cycling based on total alkalinity and nutrient data.
• Studying water mass properties based on concurrent temperature and salinity profiles.
• Assessing oceanographic conditions in the East China Sea based on the spatial coverage.

Strengths

• Includes multiple co-located chemical and physical seawater parameters.
• Data collection occurred over a defined period from 2016-06-18 to 2016-07 23.
• 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 research cruise.
