Ge , Shemin 1 ; Cutillo , Paula 2 1 University of ÃÛÌÇÖ±²¥ 2 US National Park Service Hydrogeologic systems are known to respond to earthquakes, manifested by ground water level changes, abnormal temperature and chemical concentrations in ground water. The implication of these phenomena is manifold. This presentation focuses...

Esposito , Rhea M M 1 ; Horn , Shannon 2 ; McKnight , Diane 3 1 INSTAAR 2 3 The McMurdo Dry Valleys in Antarctica are among the coldest and driest deserts on earth. Streams only flow for 6-10 weeks per year, but streams support perennial microbial mats dominated...

Dittrich , Timothy M 1 1 University of ÃÛÌÇÖ±²¥-Boulder Colloids are defined as any particle that is between 1 nanometer and 1 micrometer in diameter and can consist of mineral material and clays, microbes, and decayed plant matter. Due to their small size, transport of colloids through soil pores is...

Buckingham , Susan E 1 ; Whitney , John 2 1 University of ÃÛÌÇÖ±²¥ 2 USGS The Las Vegas Wash was a typical desert wash before settlement began in 1905. Upstream population has grown from about 5,000 in 1930 to about 1.6 million in 2004. Concurrent with a growing urban...

Bedford , David R 1 ; Small , Eric E 2 1 Department of Geological Sciences, University of ÃÛÌÇÖ±²¥ 2 Department of Geological Sciences, University of ÃÛÌÇÖ±²¥ Spatial patterns of ecohydrologic properties allow examination of spatial interactions between hydrologic, ecologic, soil, and climate parameters. We use the spatial patterns of...

Beatty , Susan W. 1 1 University of ÃÛÌÇÖ±²¥, Dept. of Geography Common fine-scale disturbances in eastern deciduous forests include treefalls, animal burrows, and effects of invasive species such as earthworms. The remnant effect of treefall disturbance is a microtopography of mounds and pits that comprise up to 60% of...
