Kimberly Wickland


I lead interdisciplinary studies that aim to increase our understanding of the complexities of ecosystem carbon cycling across terrestrial and aquatic environments; the impacts of climate, disturbance, and land use on carbon cycling and coupled biogeochemical cycles; and the implications of changing carbon dynamics for future climate and ecosystem conditions. I conduct field studies and complementary experimental laboratory studies of carbon dioxide (CO2) and methane (CH4) production, uptake, and emissions from terrestrial and aquatic systems, and the generation and fate of dissolved organic carbon (DOC). My research covers a large range of ecosystems, including wetlands, forest soils, tundra, lakes, streams, and rivers in temperate and northern high latitude regions.
