December 2010 discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients collected during the R/V Keifu Maru II cruise ks201009 in the North Pacific Ocean. The dataset was contributed by the National Oceanic and Atmospheric Administration and includes observations from December 3 to December 22, 2010.
Use Cases
- Modeling ocean acidification dynamics based on dissolved inorganic carbon and pH measurements.
- Analyzing relationships between seawater chemistry and physical properties based on temperature and salinity profiles.
- Studying marine nutrient cycles based on discrete nutrient concentration data.
- Calibrating ocean carbon models based on total alkalinity and dissolved inorganic carbon measurements.
Strengths
- Includes multiple co-located chemical and physical parameters (DIC, alkalinity, pH, temperature, salinity, oxygen, nutrients).
- Data collection occurred over a defined 20-day period in December 2010.
- Originates from a specific research cruise (ks201009) with a documented EXPOCODE (49UF20101203).
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.
