Salish Sea Ocean Acidification Measurements from Cruise TN343, 2016

NCEI Accession 0206960 contains discrete water column profile data from the University of Washington's Sound to Sea cruise TN343 aboard the R/V Thomas G. Thompson. The dataset includes dissolved inorganic carbon, total alkalinity, oxygen, nutrients, temperature, and salinity from two time-series stations in Washington's Salish Sea and coastal waters. Data collection was supported by the Northwest Association of Networked Ocean Observing Systems and NOAA's Ocean Acidification Program.

Use Cases

• Modeling carbon system dynamics based on DIC and total alkalinity measurements.
• Analyzing water column stratification based on CTD-derived temperature, salinity, and pressure profiles.
• Investigating nutrient-oxygen relationships in coastal waters based on discrete nutrient and oxygen concentration data.
• Assessing spatial variability of ocean acidification parameters in the Salish Sea based on station data.

Strengths

• Data conforms to climate-quality monitoring guidelines of the Global Ocean Acidification Observing Network.
• Includes laboratory-analyzed discrete samples for key carbon and nutrient parameters.
• Full-resolution CTD downcast data and additional parameters are referenced and available from a linked portal.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a specific two-day cruise in May 2016, representing a synoptic snapshot.
