摘要：The new I.A.G./A.I.G. Working GroupSEDIBUD (Sediment Budgets in Cold Environments)(http://www.geomorph.org/wg/wgsb.html)builds up on activities which were started within theEuropean Science Foundation (ESF) NetworkSEDIFLUX (Sedimentary Source-to-Sink Fluxes inCold Environments, 2004–2006)(see: http://www.ngu.no/ sediflux,http://www.esf.org/ sediflux).Changes in climate have a major impact on Earthsurface systems, especially in high-latitude andhigh-altitude cold environments. Such changes havea major impact on sediment transfer processes. Themajor aim of I.A.G./A.I.G. SEDIBUD is to providean integrated quantitative analysis of sediment transfers,nutrient fluxes and sediment budgets acrossa range of key cold environments. Such an analysishas so far been lacking. The primary focus is on theimpact on sediment transfer processes in response toa variety of climate change scenarios at a scale, whichincorporates sediment flux processes from source tosink. In order to perform a fully integrated study ofsource to sink sediment fluxes and sediment budgetsin cold environments, SEDIBUD analyses the keycomponents of weathering, chemical denudation,erosion, aeolian processes, mass movements, fluvialtransfers/transport, glacial sediment transfers, andsedimentation in lakes, fjords and coastal areas.SEDIBUD is also considering the impact of humanactivity on the environmental sites being studied andhow this might relate to climate change.
