Dissolved inorganic carbon, total alkalinity, pH on total scale, nutrients, and other vari

Southeast U.S. Shelf and Gulf of Mexico surface waters were sampled from 34 stations during a November 2019 research cruise. The dataset contains discrete measurements of dissolved inorganic carbon, total alkalinity, pH, and nutrients collected to monitor the outflow of the Shark River Slough and red tide effects. Data were collected by NOAA's Ocean Acidification Program and analyzed by the Atlantic Oceanographic and Meteorological Laboratory.

Use Cases

• Monitor coastal ocean acidification trends based on dissolved inorganic carbon and pH measurements.
• Assess the influence of riverine outflow on coastal chemistry based on nutrient and alkalinity data.
• Validate regional ocean carbon models based on discrete surface water carbon chemistry observations.
• Study the relationship between nutrient concentrations and red tide events in the Gulf of Mexico.

Strengths

• Data collection follows a structured bi-monthly sampling program at 34 stations.
• Measurements are performed by a NOAA laboratory (AOML), suggesting standardized analytical protocols.
• Dataset has a specific temporal scope from 2019-11-18 to 2019-11-24.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the specific cruise track and stations.
