Yokochi co-authors groundwater 4He paper
Reika Yokochi co-authored a Nature Geoscience paper entitled “Continental degassing of 4He by surficial discharge of deep groundwater”. The study of Guarani Aquifer, one of the world’s largest freshwater aquifer systems, revealed that deep groundwater accumulates 4He produced in the crust over a one-million-year time scale, and plays a major role in transporting 4He to the atmosphere.

Grad Student Rebecca Fischer Investigates How Rare Earth Is
Rebecca Fischer, a graduate student in the Department of the Geophysical Sciences, studies how the Earth formed and evolved to the planet we see today. In a recent study, highlighted by Astrobiology Magazine, Rebecca explored whether the chemical evolution of the Earth was a natural consequence of how the Solar System formed, or if it resulted from a set of rare circumstances.
Yang and Abbot show habitable zone depends on planetary rotation rate
In a paper published in the Astrophysical Journal Letters and covered by Astrobiology Magazine, postdoc Jun Yang and assistant professor Dorian Abbot have made calculations with global climate models showing that the habitable zone may depend strongly on the planetary rotation rate.
Kite estimates atmospheric pressure on Mars 3.6 billion years ago
Edwin Kite, who will be joining the faculty in January, was able to estimate the atmospheric pressure on Mars 3.6 billion years ago through a statistical analysis of observable impact craters dating from that era. This work is important because it constrains the total pressure of carbon dioxide, which was previously believed to have kept early Mars warm enough to allow liquid water, to be relatively low.

Chamberlin postdoc Sora Kim studies shark teeth
A study published in Geology by Chamberlin postdoctoral scholar Sora Kim analyzed the isotopic composition of shark teeth to reveal increased freshwater runoff to the Arctic Ocean during the Eocene greenhouse (38 - 50 million years ago). A article in UChicagoNews on the work can be found here.

Fred Ciesla Elected Fellow of the Meteoritical Society
DoGS Associate Professor Fred Ciesla was elected as a Fellow of The Meteoritical Society in recognition of his contributions to the study of meteoritics. This is a rare honor only given to 1% of members every two years. Ciesla's research focuses on using meteorites to understand the physical processes that control the formation and evolution of planetary systems.

PNAS paper shows dynamical downscaling not worth it
A new study published in the Proceedings of the National Academy of Sciences by graduate student Michael Glotter and Associate Professor Liz Moyer suggests little benefit to expensive dynamical downscaling methods to bridge the gap between climate model resolution and the finer-spatial-scale projections needed for agricultural assessments.
Graham Slater accepts assistant professorship
Graham Slater will join Tiffany Shaw, Malte Jansen, and Edwin Kite as new members of the faculty next year. Graham is a macroevolutionary biologist who uses sophisticated statistical techniques to combine information obtained from genetic dating and the fossil record to make inferences about evolutionary radiation.
Professor Tiffany Shaw to Join Department
Professor Tiffany Shaw will join the Department of the Geophysical Sciences next year, along with other new members of the faculty Malte Jansen and Edwin Kite. Tiffany studies gravity wave drag parameterization, stratosphere-troposphere coupling and its role in tropospheric climate variability and anthropogenic climate change, and tropospheric moisture and momentum transport between the tropics and the midlatitudes.
Professor Grossman Elected to the American Academy of Arts and Sciences
Professor Lawrence Grossman has been elected to the American Academy of Arts and Sciences (read more). Professor Grossman is a meteoriticist who studies the origin of solid matter in the solar system.

Rebecca Fischer awarded American Fellowship by AAUW
Graduate student Rebecca Fischer was awarded the prestigious American Fellowship by the American Association of University Women. This award, which dates back to 1888, is highly competitive, with only about 70 recipients this year across all areas of scholarship.
