Aiken , George 1 1 US Geological Survey A number of biogeochemical processes that influence the fate, bioavailability and transport of mercury (Hg) in aquatic systems are mediated by the interaction of Hg with dissolved organic matter (DOM). In many cases, the interactions between Hg and DOM in a particular...

Williams , Mark W 1 1 CU-Â鶹¹ÙÍø Mountains, like the polar regions, are likely to experience the effects of global warming before lowland sites. Seasonally snow-covered areas are like canaries in a coal mine; early warning systems that climate change is occurring. Small increases in air temperature can cause snowfall...

Vogel , Richard M 1 1 Tufts University, Department of Civil and Environmental Engineering A general introduction to the new field of ‘hydromorphology’ will be given. Hydromorphology is to hydrology, as geomorphology is to geology. Hydromorphology deals with the evolution and structure of systems. There are very few water systems...

Segura , Catalina 1 ; Pitlick , John 2 1 University of Colorado 2 University of Colorado The spatial variability of sediment transport intensity at the reach scale is controlled both by the available shear stress, Ï„, and the grain size distribution of the channel bed. This variability creates patches...
