Remote Sensing and Dryland Management

Drylands (areas characterized by low precipitation, high evapotranspiration, and low soil moisture) occupy around 40-45% of the earth’s surface. Many drylands contain high biodiversity and provide essential ecosystem services (e.g., livestock forage, agricultural production, pollination) for nearly 1/3 of the world’s population who live in drylands.  Given limited precipitation and other...

Geochemistry and hydrology of perched groundwater springs: assessing elevated uranium concentrations at Pigeon Spring relative to nearby Pigeon Mine, Arizona (USA)

The processes that affect water chemistry as the water flows from recharge areas through breccia-pipe uranium deposits in the Grand Canyon region of the southwestern United States are not well understood. Pigeon Spring had elevated uranium in 1982 (44 μg/L), compared to other perched springs (2.7–18 μg/L), prior to mining operations at the nearby...

Element concentrations in surface soils of the Coconino Plateau, Grand Canyon region, Coconino County, Arizona

This report provides the geochemical analyses of a large set of background soils collected from the surface of the Coconino Plateau in northern Arizona. More than 700 soil samples were collected at 46 widespread areas, sampled from sites that appear unaffected by mineralization and (or) anthropogenic contamination. The soils were analyzed for 47...
