Research from the Tucson Basin indicates that tracers can be used to distinguish surface and subsurface recharge, providing crucial data to support sustainable water management in arid environments.
Cesium-137 acts as a tracer to evaluate the efficiency of conservation methods.
A new study refines our understanding of marine residence times of iron, which supports carbon-sequestering sea life, offering valuable data to inform biogeochemical models.
Variations in hot spring geochemistry from adjacent mountain ranges with different styles of faulting highlight the influence of crustal-scale structures on circulating fluids in the Peruvian Andes.
Oxygen isotope ratios in cave deposits reflect past climates, but interpreting these data is not straightforward. A new study explores what these ratios really tell us.
New developments in the science of ore genesis and exploration could address the challenges of finding new mineral deposits for our increasingly materialistic world.
Radioactive isotope tracers can be used to determine the relationship between the ages of water that is stored in soil and bedrock, water in streams, and the water used by vegetation.
Painstaking measurements of isotopes and their relative abundance in rocks have illuminated the hidden inner Earth and our planet’s origins and shadowy past for much of the preceding century.
Dissolved thorium isotopes light the way to a more thorough understanding of how different elements enter marine environments—and how long they stay there.
Cosmogenic silicon-based estimates of the amount of biogenic silica stored in clays along continental margins could explain the large discrepancy in the nutrient’s global marine budget.
