First, dynamic compression experiments will measure the spin state and structure of dense iron-bearing silicate melts. Second,...
This two-year, $389,244 National Science Foundation project grant funds the development of numerical modeling to investigate thermo-chemical convection in Earth's core and implications for geomagnetic field evolution. Funded under the NSF Geosciences program (CFDA 47.050), the modeling aims to better understand how Earth's magnetic field has been maintained over billions of years through fluid motion in its liquid outer core. The Carnegie Institution for Science will receive funding to support a...
This Project Grant award of $213,433, provided by the National Science Foundation (NSF) Integrative Activities program (CFDA 47.083), will support a six-month research fellowship at the Carnegie Institution for Science in Washington, D.C. The goal is to enhance the lead researcher's career in data science and geoinformatics through collaboration with the Deep-Time Data Driven Discovery (4D) Initiative. The project will establish a reusable methodology for efficiently deploying data science in...
Carnegie Institution of Washington, doing business as Carnegie Institution for Science, was awarded a $183,579 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences program (CFDA 47.050). The grant will fund experimental research into controls on clumped isotope signatures of methane in deep-sea hydrothermal vents from May 15, 2023 through April 30, 2026. Specifically, the grantee will conduct laboratory experiments to explore the isotopic...
This National Science Foundation (NSF) Geosciences grant (CFDA 47.050) will provide $490,000 to the Carnegie Institution For Science to acquire an advanced X-ray detector, the EIGER2 S CdTe 9M, for the Advanced Photon Source at Argonne National Laboratory. The new detector will enhance the institution's capabilities to conduct in-situ, high-pressure and high-temperature studies of the structure and composition of Earth and planetary materials, including minerals, melts, and iron alloys. This...
This $199,998 Project Grant was awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) to the Carnegie Institution of Washington, doing business as the Carnegie Institution for Science, for a two-year collaborative research project. The project aims to investigate the crystal structure, melting, and crystallization of iron-sulfur (Fe-S) alloys under the extreme pressure and temperature conditions of the Earth's core. The research team, which includes scientists from Arizona State University, Carnegie Institution, and the University of South Florida, will perform dynamic compression experiments and molecular dynamics simulations to provide essential data for understanding the temperature and structure of the Earth's core. This work addresses key questions about the influence of sulfur on iron melting and the potential for Fe-S crystallization to explain heterogeneities in the Earth's inner core. The project also supports the collaborative mentoring of three early-career researchers and the development of educational materials to enhance science learning.
