Salish Sea Ocean Acidification Measurements from 2013 Cruise TN301

Discrete water column profile data for nine stations in Washington State's Salish Sea and coastal waters, collected from September 22 to 25, 2013 aboard the R/V Thomas G. Thompson. The dataset includes measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, oxygen, and nutrients, designed to provide a synoptic snapshot related to ocean acidification. Data collection was conducted by the Northwest Association of Networked Ocean Observing Systems (NANOOS) in support of climate-quality monitoring guidelines.

Use Cases

• Modeling ocean acidification dynamics based on synoptic DIC and alkalinity measurements.
• Analyzing vertical water column structure based on CTD profile data for temperature, salinity, and oxygen.
• Studying nutrient distributions and their relationship to carbon parameters in coastal environments.
• Calibrating or validating sensor data using discrete laboratory analyses for key biogeochemical variables.

Strengths

• Data conforms to climate-quality monitoring guidelines of the Global Ocean Acidification Observing Network.
• Includes nine time-series stations providing spatial coverage of the Salish Sea and adjoining coastal waters.
• Combines high-resolution CTD sensor data with discrete laboratory analyses for key parameters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single cruise in 2013, representing a specific temporal snapshot.
