The National Science Foundation Division of Environmental Biology awarded Dartmouth College $829,340 under the Biological Sciences (CFDA 47.074) federal grant program to study how changing snow conditions affect soil biogeochemistry. Specifically, the award will support research to understand how reductions in persistent winter snowpack due to climate change are increasing soil climate variability and redox fluctuations. The grantee will construct an in situ experiment manipulating winter climate treatments and measure various soil environmental variables, biogeochemical fluxes including greenhouse gas production, and nutrient and metal leaching through the soil profile. Additionally, the award provides graduate and undergraduate education in winter ecology, experiments, and data analysis. Broader impacts include engaging community members such as public school students to help monitor snow and soil conditions, advancing scientific understanding of climate change impacts on winter-affected ecosystems and soils. The five-year project period began March 1, 2023 and is expected to be completed by February 29, 2028.
