Quantitative Allalysis ofSedimelltary Fluxes and Budgets in Changing Cold Climate Environments: Scaling /ssues, New Teclllliques, Modelling and Data Management Authors: Client:

Climate change affects all Earth surface systems but with the arguably greatest impact in high-latitude and high-altitude cold environments. In these areas, c1imate change shapes earth surface proeesses not just by altering vegetation cover and human activities but also through its impact on frost penetration and duration within the ground surface layers. All of these factors influence pattems of erosion, transport and deposition of sediments and related fluxes (e.g., nutrients, solutes, carbon). Tt is a challenge to develop a better understanding of how these faetors combine to affect sedimentary transfer proeesses and sediment budgets in eold environments. Our baseline knowledge on the weathering, erosion, sedimentary transfer and depositional proeesses operating within Holocene to eontemporary c1imates forms our basis for predieting the consequences of predicted future c1imate change and related vegetation cover changes. However, much of this information is!imited in terms of spatial and temporal coverage and needs to be extended and consolidated. Only when we have these reliable models response to landscape and c1imate change we will have fuller understanding of probable future changes to these regions. Central issues ofthis Fourth SED/BUD Workshop are: • Scaling issues within sediment budget studie
