North Pacific and East China Sea Seawater Chemistry Profiles from 2014

The North Pacific Ocean and East China Sea are the focus of this dataset of discrete seawater measurements collected from April 10 to May 5, 2014, during the R/V Keifu Maru II cruise ks201403. It includes profiles of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients. The data was contributed by the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements.
• Analyzing marine carbon cycling based on total alkalinity and nutrient data.
• Studying water mass properties and mixing based on concurrent temperature and salinity profiles.
• Investigating biological productivity based on oxygen and nutrient concentrations.

Strengths

• Data collection covers a specific cruise from April 10 to May 5, 2014, providing a temporal snapshot.
• Includes multiple key oceanographic variables measured concurrently from discrete samples.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
