Washington State marine waters in the Salish Sea and adjoining coastal waters were sampled during a cruise from 2015-11-16 to 2015-11-19 aboard the R/V Thomas G. Thompson. Ten time-series stations provided discrete profile measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, oxygen, and nutrients. The dataset was collected by the Washington Ocean Acidification Center and NOAA's Ocean Acidification Program to support climate-quality monitoring.
Use Cases
- Analyze carbonate system dynamics based on dissolved inorganic carbon and total alkalinity measurements.
- Model ocean acidification impacts on coastal ecosystems based on synoptic carbon and biogeochemical parameters.
- Correlate physical water column properties with chemical concentrations based on CTD and discrete sample data.
- Assess nutrient distributions in relation to oxygen concentrations based on laboratory analyses of discrete water samples.
Strengths
- Data conforms to climate-quality monitoring guidelines of the Global Ocean Acidification Observing Network.
- Includes full-resolution CTD downcast data and additional sensor data accessible via an external portal.
- Sampling covered ten time-series stations providing a synoptic snapshot across the Salish Sea.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; the dataset represents a single cruise in 2015.
