Soil Organic Carbon Estimates for Mexico

Map of Mexico's soil organic carbon.

(A) Digital map of soil organic carbon (kg/m2) at 1 m depth and 90 m spatial resolution. The black and blue colored areas are urban areas and water bodies. (B) An area in northern Mexico illustrating the level of detail achieved by mapping across 90 m grids.

Estimates of soil organic carbon are now available from Mexico at a 90 meter resolution.

Burn Severity Index of Canadian Ecoregions

Map of study area.

Study area included sites burned in 2014 and 2015 in the southeastern portion of the Northwest Territories and northern Alberta of Canada. The study area includes all 2014 and 2015 fires within a radius of approximately 300 km from Great Slave Lake.

Pre- and post-fire Landsat images were used to classify burn severity of soil organic matter across portions of arctic Canada.

Year-round Soil CO2 Measurements in Alaska

Sites of forced diffusion chamber deployment

Forced diffusion chambers were established at the seven sites along a south-to-north transect from near Fairbanks to Toolik Lake, Alaska.

Soil surface CO2 efflux in Alaska is available from the ABoVE field campaign.

Soil Carbon Content Across the Great Plains

Visualization of Surface Soil Organic Carbon Fractions across the Great Plains Region, USA.

Visualization of surface soil organic carbon fractions across the Great Plains region, USA, using nearest neighbor interpolation (from the ORNL DAAC Spatial Data Access Tool).

A new dataset provides gridded estimates of organic carbon in soil at 1 km resolution across four US states.
