Discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, chlorofluorocarbons, temperature, salinity, oxygen, and nutrients collected during the R/V Keifu Maru II cruise ks201406 from 2014-09-04 to 2014-10-19. The dataset was collected by the National Oceanic and Atmospheric Administration and is part of the Ocean Carbon and Acidification Data System.
Use Cases
- Modeling ocean acidification based on dissolved inorganic carbon and pH measurements.
- Studying carbon cycling and water mass ventilation based on chlorofluorocarbon (CFC-11, CFC-12) data.
- Analyzing nutrient dynamics and primary productivity based on nutrient concentration profiles.
- Calibrating oceanographic models using co-located temperature, salinity, and oxygen measurements.
Strengths
- Measurements cover a specific 46-day research cruise in 2014.
- Includes multiple co-located chemical and physical parameters for water column profiles.
- Data is associated with the NOAA Ocean Carbon and Acidification Data System.
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.
