National Oceanic and Atmospheric Administration collected dissolved inorganic carbon, total alkalinity, pH, and nutrient data in the Gulf of Alaska region. Samples were gathered via discrete sampling using Niskin bottles and other instruments between May 2007 and July 2013. The dataset is part of the Ocean Carbon and Acidification Data System.
Use Cases
- Modeling ocean acidification impacts based on pH and alkalinity measurements
- Studying nutrient dynamics in coastal waters based on nitrate, phosphate, and silicate data
- Analyzing carbon system variability over time based on dissolved inorganic carbon records
- Correlating biological activity with chemical parameters based on chlorophyll-a (Chla) data
Strengths
- Multi-year temporal coverage spanning from 2007 to 2013
- Includes multiple key ocean chemistry variables such as pH, nutrients, and carbon parameters
- Data collected via standardized discrete sampling methods like Niskin bottles
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 bias inherent to the Gulf of Alaska region
