Coupling soil field data with remote sensing to inventory permafrost soil carbon for two small Arctic river deltas, Alaska

Arctic river deltas are highly dynamic environments at the interface of land to ocean. Arctic deltas are underlain by permafrost deposits, which are highly vulnerable to a warming climate. The amount of soil carbon stored in these deltas and potentially vulnerable to mobilization due to permafrost t...
