Integrative Approaches to Advance Understanding of Soil and Sediment Biogeochemical Functioning I Posters

Submit an Abstract to this Session



Session ID#: 26151

Session Description:
The biogeochemical functioning of soils and sediments is linked to interconnected physical, chemical and microbial processes, which are modulated by environmental and climatic drivers on a wide range of temporal and spatial scales. Understanding the response of soil and sediment biogeochemistry to environmental changes is greatly enhanced by using integrative approaches that combine characterization of multidisciplinary aspects of the system studied. Technological developments have led to the availability of sophisticated sensors, automated monitoring systems and sample characterization methods that can capture a wide range of parameters under dynamic conditions ( e.g., wetting and drying, flooding, freezing and thawing, groundwater-surface water interactions and flow regimes). This session facilitates in-depth exchanges of concepts, data, measurement techniques, and modelling approaches. We particularly welcome presentations on the role of coupled biogeochemical processes in the subsurface environment, and the responses of microbial communities, carbon and nutrient fluxes, and turnover of organic matter under dynamic conditions.
