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

From March 17 to 19, 2016, discrete water samples and CTD casts were collected at 9 stations in the Salish Sea and adjoining coastal waters of Washington State. The dataset contains measurements of dissolved inorganic carbon, total alkalinity, oxygen, nutrients, temperature, and salinity, designed as a synoptic snapshot for ocean acidification research. It was collected aboard the NOAA Ship Bell M. Shimada (cruise SH1604) in support of NOAA and NANOOS monitoring objectives.

Use Cases

• Modeling carbonate system parameters based on measured DIC and total alkalinity.
• Analyzing vertical water column structure based on CTD-derived temperature, salinity, and pressure profiles.
• Investigating nutrient dynamics and their relationship to oxygen concentrations.
• Assessing spatial variability of ocean acidification indicators across the Salish Sea.

Strengths

• Data collection conforms to climate-quality monitoring guidelines of the Global Ocean Acidification Observing Network.
• Includes discrete laboratory analyses for key parameters (DIC, alkalinity, nutrients) alongside continuous sensor CTD data.
• Covers 9 time-series stations providing a synoptic spatial snapshot.

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 3-day cruise in 2016, limiting temporal scope.
