Dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, temperature, salini

From April 7 to May 7, 2016, this dataset contains discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients collected during the R/V Keifu Maru II cruise ks201604. The data was gathered by the National Oceanic and Atmospheric Administration (NOAA) in the East China Sea and North Pacific Ocean.

Use Cases

• Modeling ocean carbon uptake based on dissolved inorganic carbon and total alkalinity measurements.
• Assessing ocean acidification trends based on pH on the total scale.
• Studying nutrient dynamics and their relationship to oxygen levels in coastal and open ocean regions.
• Calibrating and validating satellite-derived sea surface temperature and salinity products.

Strengths

• Data covers a specific one-month cruise from 2016-04-07 to 2016-05-07, providing a temporal snapshot.
• Includes multiple key oceanographic variables: dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients.
• Sourced from the authoritative National Oceanic and Atmospheric Administration (NOAA).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic bias inherent to the specific cruise track in the East China Sea and North Pacific.
