Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, temperature, salinity, oxygen, and nutrients collected during the R/V Keifu Maru II cruise ks201708. The data was collected in the Sea of Japan from November 7 to December 8, 2017. The dataset originates from the National Oceanic and Atmospheric Administration.
Use Cases
- Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements.
- Analyzing marine biogeochemical cycles based on nutrient and oxygen profiles.
- Studying water column properties based on temperature and salinity profiles.
- Calibrating oceanographic sensors based on discrete alkalinity and carbon measurements.
Strengths
- Data covers a specific cruise (ks201708) with a known EXPOCODE (49UF20171107).
- Measurements include multiple key ocean chemistry parameters (DIC, alkalinity, pH, nutrients).
- Dataset has a precise temporal coverage from 2017-11-07 to 2017-12-08.
- Dataset originates from a recognized authority (NOAA).
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.
