Biogeochemical Cycling
Biogeochemical Cycling
Oxygen, carbon, nutrients, and water cycle together through abiotic and biotic parts of the Earth to support life. Climate, geology, hydrology, ecosystems, and human activities all affect this cycling. The Ecosystems Land Change Science Program applies multidisciplinary research to document long-term patterns and drivers of biogeochemical cycling and support developing sustainable management plans

Holocene Hydroclimate of Western North America
The objectives of this project are to reconstruct detailed histories of Holocene hydroclimate and corresponding environmental change from geological archives such as lake sediment, peat, and wood to more fully understand past, ongoing, and future change and its impacts.
Terrestrial Records of Holocene Climate Change: Fire, climate and humans
Large wildfires have raged across the western Americas in the past decade including the Las Conchas, New Mexico fire that burned 44,000 acres in a single day in 2011 (Orem and Pelletier, 2015, Geomorphology 232: 224-238, and references therein), the 2016 Fort McMurray, Alberta fire that required evacuating an entire city, and the 2015 Alaskan fire season that burned more than 5 million acres...
