A $2.7 million multi-disciplinary, multi-institutional NSF-Frontiers of Earth Science grant has been awarded to a team led by Carnegie’s Lara Wagner to study an active flat slab in Colombia. A flat slab is produced when a tectonic plate descends to depths of about 30 to 60 miles (~50-100 km) then flattens and travels horizontally for hundreds of miles before descending farther into Earth’s mantle. Flat slabs are unlike standard subduction, in which a tectonic plate descends more steeply beneath another plate directly into the Earth. 

Because flat slabs travel horizontally directly beneath the overriding continents for hundreds of miles, they have more extensive

Washington, DC—The first minerals to form in the universe were nanocrystalline diamonds, which condensed from gases ejected when the first generation of stars exploded. Diamonds that crystallize under the extreme pressure and temperature conditions deep inside of Earth are more typically encountered by humanity. What opportunities for knowledge are lost when mineralogists categorize both the cosmic travelers and the denizens of deep Earth as being simply “diamond”?

Could a new classification system that accounts for minerals’ distinct journeys help us better understand mineralogy as a process of universal and planetary evolution?

The Office of the President has selected two new Carnegie Venture Grants. Peter Driscoll of the Department of Terrestrial Magnetism and Sally June Tracy of the Geophysical Laboratory were awarded a venture grant for their proposal Carbon-rich Super-Earths: Constraining Internal Structure from Dynamic Compression Experiments. Plant Biology’s Sue Rhee and Global Ecology’s Joe Berry and Jen Johnson were awarded a Venture Grant for their project Thermo-adaptation of Photosynthesis in Extremophilic Desert Plants.

Carnegie Science Venture Grants ignore conventional boundaries and bring together cross-disciplinary researchers with fresh eyes to explore different questions.

Washington, DC—Which of Earth’s features were essential for the origin and sustenance of life? And how do scientists identify those features on other worlds?

A team of Carnegie investigators with array of expertise ranging from geochemistry to planetary science to astronomy published this week in Science an essay urging the research community to recognize the vital importance of a planet’s interior dynamics in creating an environment that’s hospitable for life.

With our existing capabilities, observing an exoplanet’s atmospheric composition will be the first way to search for signatures of life elsewhere. However, Carnegie’s

High-elevation, low relief surfaces are common on continents. These intercontinental plateaus influence river networks, climate, and the migration of plants and animals. How these plateaus form is not clear. Researchers are studying the geodynamic processes responsible for surface uplift in the Hangay in central Mongolia to better understand the origin of high topography in continental interiors.

This work focuses on characterizing the physical properties and structure of the lithosphere and sublithospheric mantle, and the timing, rate, and pattern of surface uplift in the Hangay. They are carrying out studies in geomorphology, geochronology, thermochronology, paleoaltimetry,

Andrew Steele joins the Rosetta team as a co-investigator working on the COSAC instrument aboard the Philae lander (Fred Goesmann Max Planck Institute - PI). On 12 November 2014 the Philae system will be deployed to land on the comet and begin operations. Before this, several analyses of the comet environment are scheduled from an approximate orbit of 10 km from the comet. The COSAC instrument is a Gas Chromatograph Mass Spectrometer that will measure the abundance of volatile gases and organic carbon compounds in the coma and solid samples of the comet.

Established in June of 2016 with a generous gift of $50,000 from Marilyn Fogel and Christopher Swarth, the Marilyn Fogel Endowed Fund for Internships will provide support for “very young budding scientists” who wish to “spend a summer getting their feet wet in research for the very first time.”  The income from this endowed fund will enable high school students and undergraduates to conduct mentored internships at Carnegie’s Geophysical Laboratory and Department of Terrestrial Magnetism in Washington, DC starting in the summer of 2017.

Carbon plays an unparalleled role in our lives: as the element of life, as the basis of most of society’s energy, as the backbone of most new materials, and as the central focus in efforts to understand Earth’s variable and uncertain climate. Yet in spite of carbon’s importance, scientists remain largely ignorant of the physical, chemical, and biological behavior of many of Earth’s carbon-bearing systems. The Deep Carbon Observatory (DCO) is a global research program to transform our understanding of carbon in Earth. At its heart, DCO is a community of scientists, from biologists to physicists, geoscientists to chemists, and many others whose work crosses these

Scientists simulate the high pressures and temperatures of planetary interiors to measure their physical properties. Yingwei Fei studies the composition and structure of planetary interiors with high-pressure instrumentation including the multianvil apparatus, the piston cylinder, and the diamond anvil cell. 

The Earth was formed through energetic and dynamic processes. Giant impacts, radioactive elements, and gravitational energy heated the  planet in its early stage, melting materials and paving the way for the silicate mantle and metallic core to separate.  As the planet cooled and solidified geochemical and geophysical “fingerprints” resulted from

Roiling cauldrons of liquid-laden material flow within Earth’s rocky interior. Understanding how this matter moves and changes is essential to deciphering Earth’s formation and evolution as well as the processes that create seismic activity, such as earthquakes and volcanoes. Bjørn Mysen probes this hidden environment in the laboratory and, based on his results, models can help explain what goes on in this remote realm.

Mysen investigates changes in the atomic properties of molten silicates at high pressures and temperatures that pervade the interior Earth. Silicates comprise most of the Earth's crust and mantle. He uses devices, such as the diamond anvil

What sets George Cody apart from other geochemists is his pioneering use of sophisticated techniques such as enormous facilities for synchrotron radiation, and sample analysis with nuclear magnetic resonance (NMR) spectroscopy to characterize hydrocarbons. Today, Cody  applies these techniques to analyzing the organic processes that alter sediments as they mature into rock inside the Earth and the molecular structure of extraterrestrial organics.

Wondering about where we came from has occupied the human imagination since the dawn of consciousness. Using samples from comets and meteorites, George Cody tracks the element carbon as it moves from the interstellar medium, through

Peter Driscoll studies the evolution of Earth’s core and magnetic field including magnetic pole reversal. Over the last 20 million or so years, the north and south magnetic poles on Earth have reversed about every 200,000, to 300,000 years and is now long overdue. He also investigates the Earth’s inner core structure; core-mantle coupling; tectonic-volatile cycling; orbital migration—how Earth’s orbit moves—and tidal dissipation—the dissipation of tidal forces between two closely orbiting bodies. He is also interested in planetary interiors, dynamos, upper planetary atmospheres and exoplanets—planets orbiting other stars. He uses large-
