Washington, DC— A new approach to analyzing seismic data reveals deep vertical zones of low seismic velocity in the plumbing system underlying Alaska’s Cleveland volcano, one of the most-active of the more than 70 Aleutian volcanoes. The findings are published in Scientific Reports by Helen Janiszewski, recently of Carnegie, now at the University of Hawaiʻi at Mānoa, and Carnegie’s Lara Wagner and Diana Roman. 

Arc volcanoes like Cleveland form over plate boundaries where one tectonic plate slides beneath another. They are linked to the Earth’s mantle by complex subsurface structures that cross the full thickness of the planet's crust. These

Washington, D.C.— Carnegie trustee emeritus Frank Press, a National Medal of Science laureate and former president of the National Academy of Sciences, died January 29 at his home in Chapel Hill, N.C. He was 95. Press was active on the Carnegie board of trustees for 14 years and was the Cecil and Ida Green Senior Fellow at the institution’s Department of Terrestrial Magnetism from 1993 to 1997.

A distinguished geophysicist whose contributions to plate tectonics revolutionized the field, Press authored more than 150 papers and co-authored two foundational Earth science textbooks. He also made tremendous contributions to science policy and helped shape the U.S.

Washington, DC — Richard Carlson, director of Carnegie’s Earth and Planets division, has been chosen to receive the Geochemical Society’s highest honor, the Victor Moritz Goldschmidt Award, in recognition of his forefront research into the formation of the Solar System and the geologic history of the Earth, the society announced Tuesday.

The society will present the award to Carlson at the Goldschmidt Conference, to be held in Honolulu in June.

“I am deeply honored to receive the V.M. Goldschmidt Award, which recognizes our efforts to understand the origin and evolution of Earth’s continental crust on Earth and the consequences of its formation

Washington, DC— A “cold Neptune” and two potentially habitable worlds are part of a cache of five newly discovered exoplanets and eight exoplanet candidates found orbiting nearby red dwarf stars, which are reported in The Astrophysical Journal Supplement Series by a team led by Carnegie’s Fabo Feng and Paul Butler.

The two potentially habitable planets are orbiting GJ180 and GJ229A, which are among the nearest stars to our own Sun, making them prime targets for observations by next-generation space- and land-based telescopes.  They are both super-Earths with at least 7.5 and 7.9 times our planet’s mass and orbital periods of 106 and 122 days

The WGESP developed a Working List of extrasolar planet candidates, subject to revision. In most cases, the orbital inclination of these objects is not yet determined, which is why most should still be considered candidate planets. The WGESP ended its six years of existence in August 2006, with the decision of the IAU to create a new commission dedicated to extrasolar planets as a part of Division III of the IAU.

Peter van Keken studies the thermal and chemical evolution of the Earth. In particularly he looks at the causes and consequences of plate tectonics; element modeling of mantle convection,  and the dynamics of subduction zones--locations where one tectonic plate slides under another. He also studies mantle plumes; the integration of geodynamics with seismology; geochemistry and mineral physics. He uses parallel computing and scientific visualization in this work.

He received his BS and Ph D from the University of Utrecht in The Netherlands. Prior to joining Carnegie he was on the faculty of the University of Michigan.

Hélène Le Mével studies volcanoes. Her research focuses on understanding the surface signals that ground deformations make to infer the ongoing process of the moving magma  in the underlying reservoir. Toward this end she uses space and field-based geodesy--the mathematics of the area and shape of the Earth--to identify, model and interpret this ground deformation.

She uses data from radar called Interferometric Synthetic Aperture Radar (InSAR), and data from the Global Positioning System (GPS) to characterize ground motion during volcanic unrest. She also collects gravity data, which indicate changes in mass and/or density underground. These data sets,

Geochemist Steven Shirey is researching how Earth's continents formed. Continent formation spans most of Earth's history, continents were key to the emergence of life, and they contain a majority of Earth’s resources. Continental rocks also retain the geologic record of Earth's ancient geodynamic processes.

Shirey’s past, current, and future studies reflect the diversity of continental rocks, encompassing a range of studies that include rocks formed anywhere from the deep mantle to the surface crust. His work spans a wide range of geologic settings such as volcanic rocks in continental rifts (giant crustal breaks where continents split apart), ancient and

Cosmochemist Larry Nittler studies extraterrestrial materials, including meteorites and interplanetary dust particles (IDPs), to understand the formation of the Solar System, the galaxy, and the universe and to identify the materials involved. He is particularly interested in developing new techniques to analyze different variants of the same atom—isotopes—in small samples. In related studies, he uses space-based X-ray and gamma-ray instrumentation to determine the composition of planetary surfaces. He was part of the 2000-2001 scientific team to hunt for meteorites in Antarctica.

Nittler is especially interested in presolar grains contained in meteorites and in what
