In shock-wave experiments, high-powered lasers or guns are used to send a supersonic pressure wave through a sample. This type of dynamic compression can generate immense pressure and allows for the study of impact phenomena in real time.
Gravity, the fundamental force that shaped our planet, varies across the Earth’s surface, both from place to place and over time. For more than three centuries, scientists have made gravity measurements to define the shape of the Earth.
As extreme weather, rising seas, and severe droughts bring home the reality of global climate change, we are increasingly aware of the world’s pressing need for carbon-free energy sources and reliable, affordable energy storage systems.
Simon Lock of the California Institute of Technology is interested in the formation, structure, and evolution of planets, both in our solar system and in extrasolar systems.
The research of Associate Professor at Brown University Stephen Parman focuses on the chemical evolution of the Earth, moons, and planets. He delivered a seminar titled "Tracing volatile recycling in the mantle with noble gases."
The Geophysical Laboratory's weekly seminar series continued with Heather Watson of Union College, Department of Physics and Astronomy. She presented on "Diffusion of key isotopes in iron meteorites: Constraints on closure temperatures."
The Geophysical Laboratory's weekly seminar series continues with Paolo Sossi of the Institute of Physics of the Globe of Paris. He will present: "Evaporation of moderately volatile elements from silicate melts: experiments and theory".
Mars’ organic carbon may have originated from a series of electrochemical reactions between briny liquids and volcanic minerals, according to new analyses of three Martian meteorites from a team led by the Geophysical Laboratory’s Andrew Steele published in Science Advances.
The Geophysical Laboratory's weekly seminar series continues with Caroline Dorn of the University of Zurich. She will present, "Interior characterization in multiplanetary systems: TRAPPIST-1."
The Geophysical Laboratory's weekly seminar series continues with Joe Michael of Sandia National Laboratory. He will present, "Electron backscatter diffraction in materials and planetary sciences: From welds to iron meteorites."
