Discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients were collected during the R/V Keifu Maru II cruise ks201401. The National Oceanic and Atmospheric Administration (NOAA) gathered this data in the North Pacific Ocean and East China Sea from January 7 to January 25, 2014. The dataset is part of the Ocean Carbon and Acidification Data System (OCADS).
Use Cases
- Modeling ocean acidification dynamics based on dissolved inorganic carbon and pH measurements.
- Studying carbon cycling and air-sea gas exchange based on total alkalinity and DIC data.
- Analyzing water mass properties and nutrient distributions based on salinity, temperature, and nutrient profiles.
Strengths
- Data collection covers a specific 19-day research cruise with a defined EXPOCODE (49UF20140107).
- Includes multiple co-located seawater chemistry parameters (DIC, alkalinity, pH, nutrients, oxygen).
- Spatial coverage includes two distinct ocean regions: the North Pacific Ocean and the East China Sea.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
