Gulf of Mexico Carbon and Biogeochemical Parameters from GOMECC-3 Cruise, 2017

Discrete and underway oceanographic measurements collected during the NOAA GOMECC-3 cruise in the summer of 2017. The dataset includes dissolved inorganic carbon, total alkalinity, nutrients, and other variables from 11 coastal transects in the Gulf of Mexico. This effort was conducted by the NOAA Ocean Acidification Program to support coastal monitoring and research.

Use Cases

• Modeling coastal ocean acidification dynamics based on carbon and alkalinity measurements
• Analyzing biogeochemical gradients across the Gulf of Mexico based on transect data
• Studying temporal changes in coastal carbon chemistry by comparing with 2007 and 2012 cruises
• Calibrating or validating regional ocean acidification models based on discrete and underway observations

Strengths

• Data collection was part of a systematic time series, with prior cruises in 2007 and 2012
• Coverage includes 11 transects orthogonal to the Gulf of Mexico and Atlantic coasts
• Measurements support specific NOAA Ocean Acidification Program monitoring objectives

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
