East Coast Ocean Acidification Cruise: Surface Carbon and Nutrient Data from 2015

Surface discrete measurements of dissolved inorganic carbon, total alkalinity, pH, and nutrients were collected from the NOAA Ship Gordon Gunter along the U.S. East Coast. The cruise, designated GU-15-04 ECOA1, took place from June 20, 2015, and was designed to obtain a snapshot of key parameters related to ocean acidification. The effort was in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program.

Use Cases

• Modeling coastal ocean acidification dynamics based on dissolved inorganic carbon and pH measurements.
• Analyzing spatial gradients in carbonate chemistry based on transects orthogonal to the U.S. East Coast.
• Correlating nutrient concentrations with carbon system parameters to study biogeochemical linkages.
• Establishing baseline conditions for key carbon and physical parameters in the coastal realm.

Strengths

• Data collection was part of a dedicated NOAA Ocean Acidification Program cruise designed for coastal monitoring.
• The cruise included a series of 11 transects and a comprehensive set of underway measurements along the entire route.
• Variables include key carbon system parameters (DIC, alkalinity, pH) and nutrients relevant to ocean acidification research.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic bias inherent to the specific cruise track along the U.S. East Coast.
