Ocean Acidification Chemistry Profiles from NOAA Ship Gordon Gunter

NOAA Ocean Acidification Program data includes dissolved inorganic carbon, total alkalinity, pH, and nutrients from profile and discrete measurements. Measurements were collected using CTD and Niskin bottle instruments during NOAA Ship Gordon Gunter cruises. The dataset supports coastal monitoring and research on ocean acidification effects in the Northeast US coast.

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 observations
• Analyzing nutrient dynamics in relation to acidification based on nutrient variable measurements

Strengths

• Data collected by the NOAA Ocean Acidification Program, an authoritative source
• Includes multiple key ocean acidification variables: dissolved inorganic carbon, total alkalinity, pH, and nutrients
• Profile and discrete measurements provide depth-resolved data

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 Gulf of Maine, Georges Bank, and Mid-Atlantic Bight region
