U.S. Coastal Wetland Carbon Flux and Elevation Maps with Uncertainty

Maps detail coastal wetland carbon and methane fluxes, surface elevation, and land cover change for the conterminous United States from 2006 to 2011. The dataset integrates wetland type maps with soil, biomass, and methane flux data from a literature review, and includes uncertainty estimates from a 10,000-iteration Monte Carlo analysis. It was produced by ORNL_CLOUD using the Landsat-based Coastal Change Analysis Program (C-CAP) for land cover quantification.

Use Cases

• Modeling annual carbon and methane fluxes per pixel using estimated median soil, biomass, methane, and total CO2 equivalent flux columns.
• Analyzing land cover and land cover change in the coastal zone from 2006 to 2011.
• Assessing uncertainty in carbon flux estimates via the provided Monte Carlo analysis outputs.
• Mapping the probabilistic extent of tidal elevation and coastal wetland surface elevation.
• Integrating geospatial files to create custom surfaces for regional coastal studies.

Strengths

• Includes a detailed uncertainty analysis for carbon flux estimates derived from 10,000 Monte Carlo iterations.
• Provides multi-year coverage from 2006 to 2011 at a consistent 30-meter spatial resolution.
• Synthesizes data from multiple sources: wetland change maps, literature review data, and C-CAP land cover products.

Limitations

• Conflicting last updated dates exist between sources (2011-12-31 and 2026-03 13).
• Specific row counts, file sizes, and complete column lists are not provided by any source.
• License is specified as 'other-license-specified', requiring further investigation for use terms.
