Chá Bă Mooring Validation: Ocean Chemistry and CTD Profiles from Washington Coast, 2011

Discrete water sample and CTD profile data were collected for validating a time-series mooring measuring ocean acidification. The dataset includes dissolved inorganic carbon, total alkalinity, nutrients, temperature, salinity, and oxygen from a single cruise (TN267) off La Push, Washington, in August 2011. It is a subset of a larger coastal monitoring effort by the University of Washington PRISM program and NOAA's Ocean Acidification Program spanning 2008 to 2018.

Use Cases

• Validate moored sensor measurements of ocean acidification parameters based on discrete water sample data.
• Analyze vertical profiles of carbonate chemistry and nutrients based on CTD and Niskin bottle sampling.
• Study coastal water mass properties and variability based on concurrent temperature, salinity, and oxygen measurements.
• Support calibration of biogeochemical models for the California Current System based on high-quality, climate-standard observations.

Strengths

• Data conforms to climate-quality monitoring guidelines of the Global Ocean Acidification Observing Network.
• Includes multiple co-located parameter measurements (DIC, TA, nutrients, CTD) from discrete samples for validation purposes.
• Part of a larger, decade-long monitoring program (2008-2018) providing context.

Limitations

• Row count and specific column definitions are unknown, limiting suitability assessment.
• Dataset is a single cruise snapshot (August 2011) from a specific location; temporal and spatial coverage is limited.
• Column-level documentation is absent; field semantics must be inferred after download.
