Washington State marine waters in the Salish Sea were sampled during a 2018 cruise aboard the R/V Rachel Carson. Twenty-seven stations provided discrete water samples for laboratory analysis of dissolved inorganic carbon, total alkalinity, nutrients, and oxygen, alongside CTD sensor data. The cruise was conducted by the Washington Ocean Acidification Center in support of ocean acidification monitoring.
Use Cases
- Modeling ocean acidification impacts based on dissolved inorganic carbon and total alkalinity measurements
- Analyzing coastal biogeochemical gradients based on nutrient and oxygen concentration data
- Studying water column stratification based on CTD-derived temperature, salinity, and pressure profiles
- Calibrating sensor data using discrete water sample measurements from Niskin bottles
Strengths
- Data conforms to climate-quality monitoring guidelines of the Global Ocean Acidification Observing Network
- Twenty-seven time-series stations provide a synoptic snapshot across the Salish Sea and adjoining coastal waters
- Includes both sensor-derived CTD data and laboratory-analyzed discrete water samples
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data covers a single cruise from April 2018; temporal coverage is limited
