Kimberly Wickland is a Research Ecologist for the Geosciences and Environmental Change Science Center.
I lead interdisciplinary studies that increase our understanding of the complexities of carbon cycling across terrestrial and aquatic environments; the impacts of climate, disturbance, and land use on coupled biogeochemical cycles; and the implications of changing carbon and nutrient dynamics for future climate and ecosystem conditions. My research covers a large range of ecosystems including wetlands, forests, tundra, lakes, streams, and rivers in temperate and high latitude regions.

Water Quality Across Regional Stream Networks: The Influence of Land Cover and Land Use, Climate, and Biogeochemical Processing on Spatiotemporal VarianceLand cover and land use (LC/LU), climate, and biogeochemical processing are significant drivers of water quality in streams and rivers over broad scales of space and time. As LC/LU and climate continue to change we can expect changes in water quality. This project seeks to understand the drivers of spatial and temporal variability in water quality across scales using new and existing data to...
Arctic Boreal Vulnerability Experiment (ABoVE)ABoVE: Vulnerability of inland waters and the aquatic carbon cycle to changing permafrost and climate across boreal northwestern North America. Carbon released from thawing permafrost may fuel terrestrial and aquatic ecosystems or contribute to greenhouse gas emission, leading to a potential warming feedback and further thaw.
Nome Creek Experimental WatershedThe Nome Creek Experimental Watershed (NCEW) has been the site of multiple studies focused on understanding hydrology, biogeochemistry, and ecosystem changes related to permafrost thaw and fire in the boreal forest.

A process-model perspective on recent changes in the carbon cycle of North AmericaContinental North America has been found to be a carbon (C) sink over recent decades by multiple studies employing a variety of estimation approaches. However, several key questions and uncertainties remain with these assessments. Here we used results from an ensemble of 19 state-of-the-art dynamic global vegetation models from the TRENDYv9 project to improve these estimates and study the driversAuthorsGuillermo Murray-Tortarolo, Benjamin Poulter, Rodrigo Vargas, Daniel B.

The importance of lake emergent aquatic vegetation for estimating Arctic-boreal methane emissionsAreas of lakes that support emergent aquatic vegetation emit disproportionately more methane than open water but are under-represented in upscaled estimates of lake greenhouse gas emissions. These shallow areas are typically less than ∼1.5 m deep and can be detected with synthetic aperture radar (SAR).

Heterogeneous patterns of aged organic carbon export driven by hydrologic flow paths, soil texture, fire, and thaw in discontinuous permafrost headwatersClimate change is thawing and potentially mobilizing vast quantities of organic carbon (OC) previously stored for millennia in permafrost soils of northern circumpolar landscapes. Climate-driven increases in fire and thermokarst may play a key role in OC mobilization by thawing permafrost and promoting transport of OC.
