R. Randall Schumann
I am currently a geologist in the Geosciences and Environmental Change Science Center in Denver, Colorado, conducting studies on the effects of climate change on landscape dynamics in coastal and fluvial environments.
I began my career at the USGS in 1980 with research focusing on fluvial geomorphology and sedimentology of anastomosing river channels; wetland hydrology; surficial uranium deposits; and the geology and geochemistry of radon in rocks and soils. I received the Department of Interior's Superior Service Award for my work on radon. I was a member of the Central Publications Group from 1995-1997 and was coordinator of computer support, GIS, and web services for the Earth Surface Processes Team from 1997-2000. I served as Team Chief Scientist (Center Director) of the Earth Surface Processes Team from 2002-2008 and was director of the National Ice Core Laboratory from 2007-2008.

No abstract available.Effects of weather and soil characteristics on temporal variations in soil-gas radon concentrations
Concentrations of radon-222 in soil gas measured over about 1 yr at a monitoring site in Denver, Colorado, vary by as much as an order of magnitude seasonally and as much as severalfold in response to changes in weather. The primary weather factors that influence soil-gas radon concentrations are precipitation and barometric pressure. Soil characteristics are important in determining the magnitudeAuthorsR.
