Tidal Wetland Soil Carbon Stocks for the Conterminous US

NASA provides modeled estimates of soil carbon stocks for tidal wetland areas across the Conterminous United States for the 2006-2010 period. The dataset integrates 1,959 soil cores from 49 studies across 18 coastal states with satellite-derived land cover and wetland inventory maps. Estimates were generated using four distinct modeling approaches, allowing for comparisons of uncertainty and accuracy.

Use Cases

• Comparing uncertainty and accuracy across four different soil carbon modeling approaches.
• Analyzing spatial patterns of carbon stocks in estuarine emergent, scrub/shrub, and forested wetland types.
• Validating regional carbon models using the compiled database of 1,959 empirical soil cores.
• Assessing carbon storage potential in tidal wetlands using 30 x 30-meter pixel-level estimates.

Strengths

• Model validation uses a substantial empirical foundation of 1,959 soil cores from 49 studies.
• Provides direct comparisons of uncertainty, precision, and accuracy across four distinct estimation methods.
• Offers spatially explicit 30 x 30-meter resolution estimates for the entire Conterminous US coastline.

Limitations

• Platform metadata conflicts on last updated date, with one source reporting 2026 and another 2010.
• Specific column names and the total row or pixel count are not provided in any source description.
• The dataset's license is ambiguously listed as 'other-license-specified' without clear terms.
