Using a mechanistic ecosystem model, ecosys, to demonstrate that static temperature relations cannot accurately predict wetland CH4 production and emission rates due to substrate-mediated microbial and abiotic interactions.

Using a mechanistic land model, Ecosys, to demonstrate that short-term (< 10 year) warming experiments produce emergent ecosystem carbon stock temperature sensitivities inconsistent with multi-decadal responses due to the tightly coupled, nonlinear nature of high-latitude ecosystems

A novel mathematical formulation allows accurate solution of water flow in geometrically complicated soil structures, including overturned soil layers and other soil disturbance.

Rates and controls on CO2 and CH4 production were observed for two contrasting water‐saturated tundra soils within a permafrost‐affected watershed near Nome, AK.

Most models project a long-term drying of the surface soil for the permafrost region despite increases in the net air–surface water flux.

The study provides new insight into hydrological processes of low- and high-centered polygon systems, where flow and transport field investigations are almost totally lacking.

Leadership team takes time and intentional steps to build a culture of safety and respect across the project.

Plant stoichiometric flexibility controls the CO2 fertilization effect on ecosystem carbon accumulation.

Multiple models are needed to capture true uncertainty of soil carbon fate in a changing world.

Novel bromide tracer experiments are used to develop a model of subsurface flow and transport within ice-wedge polygons.
