Coastal Ocean Acidification Measurements in the Northeast U.S., 2017

Dissolved inorganic carbon, total alkalinity, pH, and nutrient data collected from profile and discrete sample observations in the Gulf of Maine, Georges Bank, and Mid-Atlantic Bight. The dataset was gathered by the NOAA Ocean Acidification Program using CTD and Niskin bottle instruments onboard the NOAA Ship Gordon Gunter. Measurements were taken from 2017 onward to monitor changes in ocean carbon chemistry.

Use Cases

• Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements.
• Assessing impacts on calcifying organisms based on carbonate chemistry variables.
• Monitoring coastal carbon chemistry changes based on profile and discrete sample data.
• Analyzing regional variability in ocean acidification based on data from the Gulf of Maine, Georges Bank, and Mid-Atlantic Bight.

Strengths

• Data collected by the NOAA Ocean Acidification Program, an authoritative source.
• Includes multiple key variables for ocean acidification research: dissolved inorganic carbon, total alkalinity, and pH.
• Profile and discrete sample observations provide vertical and point measurements.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Northeast U.S. coast.
