Measuring Electron Activity to Constrain the Role of Soil Structure in the Formation of Biogeochemical Heterogeneity

Creator:

Wanzek, Thomas

Abstract:

Soils have a critical role in global carbon (C) cycling, containing one of the largest fast-cycling carbon stocks on earth. Robust representation of soil organic matter dynamics in Earth System Models is critical for future climate prediction. Current C cycling models assume that all C cycling in non-hydric (i.e. ‘upland’)...

Scaling, ash-driven bistability, and other agents of soilscape genesis discovered while digitally mapping soils of the Blue Mountains, Oregon

Creator:

Almquist, Vance Warner

Abstract:

This dissertation reports on four related, though separate projects. The first project details the process of carrying out a digitally augmented soil mapping (DSM) effort alongside an ongoing survey in Oregon's Ochoco National Forest (ONF) using a Random Forest algorithm. The second chapter describes a initial soil survey in Oregon's...
