The North Pacific Ocean and East China Sea are the geographic scope of this dataset. It contains discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients. Data were collected by the National Oceanic and Atmospheric Administration during the R/V Keifu Maru II cruise ks201504 from April 15 to May 4, 2015.
Use Cases
- Modeling ocean acidification dynamics based on dissolved inorganic carbon and pH measurements.
- Analyzing nutrient distributions and their relationship to biological activity based on nutrient concentration data.
- Studying water mass properties and mixing based on concurrent temperature and salinity profiles.
- Calibrating and validating ocean carbon cycle models based on discrete seawater chemistry measurements.
Strengths
- Data collection occurred during a specific research cruise (ks201504) with a known EXPOCODE (49UF20150415).
- Measurements cover multiple key seawater chemistry parameters (DIC, alkalinity, pH, nutrients) from a single source.
- The temporal coverage is precisely defined from 2015-04-15 to 2015-05-04.
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.
