We are organizing a session on the fall meeting of the AGU that would be of interest to the soil science, biogeochemistry, geomorphology and critical zone research networks: B061 - Role of Soil Erosion on Biogeochemical Cycling of Essential Elements
Lateral transport of topsoil by erosion is a primary control on the spatial distribution of essential elements in the terrestrial biosphere. Exciting advances in the understanding of multi-scale dynamics of specific elements have been assisted by the development of new tracing and monitoring technologies and modelling approaches. Nevertheless, there still remain important gaps in our understanding of how erosion controls elemental cycles at different spatial and temporal scales, particularly the regional and global relevance of the stoichiometric relationships between different elements. We invite presentations from all fields in the geosciences: studies at timescales from short term to geological; spatial scales from microbe to globe; and, approaches from empirical to theoretical. Papers addressing multiple elements would be particularly welcome. Our session will have the following invited speakers Robert Stallard (US Geological Survey) Stephen Porder (Brown University) Bob Hilton (Durham University) Sarah De Baetes (University of Exeter) CONVENERS: Asmeret Asefaw Berhe, Timothy Quine, Jennifer Dungait, Jereon Meersman CURRENT SECTION/FOCUS GROUP: Biogeosciences (B) CO-SPONSORING SECTION(S): Earth and Planetary Surface Processes (EP), Global Environmental Change (GC), Hydrology (H) As part of the AGU soil-focused SWIRL at the 2013 Fall Meeting (Global Soilsfeatureathttp://fallmeeting.agu.org/2013/scientific-program/swirls/). We hope you are planning on attending AGU and that you will consider our session. If you have any questions in this regard, please feel free to contact me or any one of the other session conveners.
