The cooling of planet Earth over time increased the water carrying capacity of the mantle and could have shrunk the oceans.Read More »Atmospheric Sciences
Fracturing during microearthquakes can cause groundwater pH drops. The change is temporary but can be equivalent to the difference between water and vinegar.Read More »Geochemistry, Mineralogy, Volcanology
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.Read More »Geochemistry, Mineralogy, Volcanology
Bubbles trapped in magma from a 1,000-year-old event reveal how scoria cones might erupt and what impact they may have on the landscape and atmosphere.Read More »Geochemistry, Mineralogy, Volcanology
A three-nation consortium is pooling geological expertise and resources to address vulnerabilities in supplies of these crucial natural resources.Read More »Geochemistry, Mineralogy, Volcanology
In situ geophysical measurements from Kenya’s Olkaria geothermal field, integrated with remote sensing and meteorological data, shed light on subsurface energy transport to and from the surface.Read More »Planetary Sciences
By analyzing sediments jostled by ground shaking, researchers have shown that two impact craters near Stuttgart were created by independent asteroid impacts rather than a binary asteroid strike. Read More »
What do a backhoe, expanding foam, half-ton concrete blocks, and a 100-meter-long hillslope slide have in common? All were part of reviving the U.S. Geological Survey’s experimental debris flow flume.Read More »
