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.
