B33B:
Soil Carbon Change and Persistence in the Anthropocene III


Submit an Abstract to this Session


Session ID#: 59910

Session Description:
Soils are essential components of the Critical Zone, that respond to and drive critical environmental changes facing the earth during the Anthropocene. Soil organic matter dynamics play a major role in determining ecosystem C storage and regulating atmospheric CO2 concentrations. How will climate change and man’s alteration of the terrestrial landscape affect soil organic matter dynamics? A better understanding of the processes which drive C cycling in soils, and the timescales at which they operate, is critical to understanding soil C feedbacks to climate change. For example, the frequency and magnitude of precipitation is a critical control of carbon cycling in dryland soils. This session will focus on empirical and modeling studies of soils and carbon: storage potential, ages and transit times of C in soils, mechanisms of stabilization/ destabilization, and ecosystem vulnerability. We welcome studies using a range of methods at different scales, from radiocarbon measurements to global modeling.
