Responses of biogeochemical cycles to climate change

Session ID#: 160072

Session Description:
As climate change progressively impacts the landscape, global biogeochemical cycles are responding in ways that we are only just starting to understand. For example, carbon stored in permafrost soils is being mobilized and transported into warmer environments where it may readily decompose; increasingly common wildfires in forested landscapes are potentially accelerating biogeochemical fluxes among the biosphere, pedosphere, and atmosphere; chemical weathering rates may be changing in response to increased temperatures or enhanced physical erosion driven by extreme weather events. This session aims to gather researchers studying biogeochemical changes in systems that are rapidly responding to climate change phenomena. We invite abstracts that quantify changes in the rates of biochemical processes and assess perturbations in the fluxes of carbon and nutrients among key reservoirs. We welcome research ranging from observational field-based studies, such as time-series measurements or analyses of sedimentary records, to studies modeling feedback between climate change and biogeochemical processes.
