Puget Sound Ocean Acidification Cruise Data from 2009

Thirty-nine time-series stations were occupied in the Salish Sea during a 2009 cruise aboard the R/V Jack Robertson. The dataset contains discrete profile measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, oxygen, and nutrients, collected to study ocean acidification. This effort was conducted by the University of Washington's PRISM program in support of the Global Ocean Acidification Observing Network guidelines.

Use Cases

• Modeling ocean acidification impacts based on dissolved inorganic carbon and total alkalinity measurements.
• Analyzing water column stratification based on CTD-derived temperature, salinity, and pressure profiles.
• Studying nutrient dynamics in estuarine systems based on nitrate, nitrite, and ammonium concentrations.
• Calibrating sensor data using discrete water samples collected via Niskin bottles.

Strengths

• Thirty-nine stations provide a synoptic snapshot of the Salish Sea.
• Data conforms to climate-quality monitoring guidelines of GOA-ON and NOAA.
• Includes both sensor (CTD) and laboratory-analyzed discrete sample data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is from a single cruise in 2009, limiting temporal analysis.
