Carleton Bern, PhD


I am a Research Soil Scientist with the U.S. Geological Survey in the Colorado Water Science Center. My research examines the geochemical interactions between water, rock, and soil in both natural and human-managed systems. I specialize in using isotopes and geochemical tracers to answer questions of both basic and applied research. Areas of focus in my recent work include:

(1) Salinity in surface waters and soils of the semiarid western U.S.

(2) Water quality in relation to uranium mining

(3) Improving the 100-year-old methodology for quantifying soil geochemical development

(4) Applying stable isotopes of water to understanding water availability in the Headwaters of the Colorado and Gunnison River Basin as part of the USGS Next Generation Water Observing System (NGWOS)
