Dissolved inorganic carbon (DIC), total alkalinity (TA), temperature, salinity, oxygen, an

From 2017-09 18 to 2017-09-28, a NOAA research cruise collected discrete water column samples at 51 stations in the Salish Sea and coastal waters of Washington and Oregon. The dataset contains measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, oxygen, and nutrients to provide a synoptic snapshot related to ocean acidification. This effort was conducted by the NOAA Ocean Acidification and Harmful Algal Bloom Programs and conforms to Global Ocean Acidification Observing Network guidelines.

Use Cases

• Model ocean acidification impacts on coastal ecosystems based on DIC and total alkalinity measurements.
• Analyze correlations between harmful algal bloom conditions and nutrient concentrations mentioned in the description.
• Study vertical water column structure and biogeochemical gradients based on discrete profile sampling.
• Calibrate and validate regional oceanographic models using synoptic physical and chemical data.

Strengths

• Data collected at 51 discrete stations, providing spatial coverage of the study region.
• Includes multiple key carbon system parameters (DIC, TA) alongside physical and nutrient measurements.
• Conforms to monitoring guidelines of the Global Ocean Acidification Observing Network.

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 2017; temporal coverage is limited.
