Coastal waters of SE Alaska, the Gulf of Alaska, and the North Pacific Ocean contain discrete sample and profile observations collected from 1985-02-12 to 2017-02-20. The data include dissolved inorganic carbon, pH, total alkalinity, temperature, salinity, and nutrients. Lisa A. Miller and James R. Christian of Fisheries and Oceans Canada collected these measurements as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Analyzing carbon storage changes in coastal waters based on total alkalinity and DIC data.
- Studying nutrient dynamics in relation to carbon chemistry based on nitrate, phosphate, and silicate measurements.
- Calibrating biogeochemical models using long-term temperature and salinity profiles.
Strengths
- Data spans a 32-year time range from 1985 to 2017.
- Includes multiple key ocean chemistry parameters (DIC, pH, alkalinity, nutrients).
- Data collection is associated with a systematic international program (CLIVAR).
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 specific cruise lines.
