NOAA Gordon Gunter Coastal Carbon Measurements

From 2010 to 2015, this dataset contains surface underway measurements of carbon dioxide partial pressure and related variables collected aboard the NOAA Ship GORDON GUNTER. It likely contains time-series data for air-sea CO2 difference, barometric pressure, salinity, and sea surface temperature across multiple coastal regions. The data are part of the Global Coastal Carbon Data Project, focusing on carbon cycle dynamics in continental margins.

Use Cases

• Calculating air-sea CO2 fluxes based on partial pressure differences.
• Analyzing seasonal and spatial variability of coastal ocean carbonate chemistry.
• Validating biogeochemical models for coastal and shelf sea systems.
• Assessing ocean acidification trends in the Gulf of Mexico and North Atlantic coastal waters.

Strengths

• Multi-year temporal coverage spanning from 2010 to 2015.
• Data collected using standardized instruments: Carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator.
• Part of the coordinated Global Coastal Carbon Data Project, suggesting consistent methodology.

Limitations

• Column names and dataset size (row count) are not provided in any source.
• Conflicting last update dates exist between platforms (e.g., 2015-10-25 vs. 2026-03-05), indicating potential metadata inconsistency.
• License information is uniformly absent across all platform entries.
