Earth critical zone and eco-geochemistry

WebThe “Critical Zone” is the thin layer between the upper surface of unweathered rock and the upper boundary of the vegetation. It is a giant reactor in which rivers and wind continuously move sediment eroded from soils. Yet soils have mantled most of this surface persistently in times before human land use. WebIsotope geochemists use isotopic ratio methods to study fundamental earth processes, and environmental and energy problems of national interest. Several EESA research programs are served by gas source, radiogenic …
