Puget Sound Cruise CAB1075: Carbon and Biogeochemical Profile Data from 27 Stations, 2017

Twenty-seven time-series stations were occupied in the Salish Sea during a 2017 cruise aboard the R/V Clifford A. Barnes. The dataset contains discrete water sample measurements for dissolved inorganic carbon, total alkalinity, nutrients, and oxygen, alongside CTD sensor data for temperature, salinity, and pressure. This effort was conducted by the Washington Ocean Acidification Center in support of climate-quality ocean acidification monitoring.

Use Cases

• Modeling ocean acidification dynamics based on dissolved inorganic carbon and total alkalinity measurements.
• Analyzing vertical water column structure based on CTD cast data for temperature, conductivity, and pressure.
• Studying nutrient distributions and their relationship to oxygen concentrations.
• Creating synoptic snapshots of biogeochemical conditions for the Salish Sea region.

Strengths

• Data collection conforms to climate-quality monitoring guidelines of the Global Ocean Acidification Observing Network.
• Includes both high-resolution CTD sensor data and laboratory-analyzed discrete water samples from 27 stations.
• Cruise was specifically designed for a synoptic snapshot of key parameters related to ocean acidification.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data is from a single cruise in July 2017, representing a specific temporal snapshot.
