Diana Roman Measures Harmonic Tremors in Mexico's Popocatépetl Volcano

Diana Roman

DTM Volcanologist Diana Roman traveled to Mexico in early March 2015 to study continuous seismic signals, also known as harmonic tremors, she's been recording with broadband seismometers in the Popocatépetl Volcano since June 2014.

Broadband seismometers were deployed by Roman and her team on the volcano back in June 2014. During her trip last month, she monitored and downloaded data from these devices to study in further detail at DTM.

Christopher Keane Dishes New Insights Into How Postdocs Can Take Advantage of the Geoscience Job Boom

Mike Beauregard in Greeneland 2014

Christopher M. Keane, director of technology and communications at the American Geosciences Institute (AGI), hosted a workshop titled “Jumping on the Employment Express – How to be Part of the Geosciences Employment Boom” on Tuesday, 31 March 2015, in the Abelson Collaboration Center as part of DTM's Postdoctoral Development Workshop series.

The workshop covered the obstacles geoscience graduates face when entering the workforce today. Keane gave important advice and provided thoughtful insights on the geoscience employment boom happening right now and how postdocs can take better advantage of it when looking for a job. Notes from the workshop and a copy of his powerpoint presentation are available. 

Keane received his Ph.D. in marine, estuarine, and environmental science from the University of Maryland in 1997. He began work at AGI as a research associate in 1997, and advanced to his current position in 2000. In 2004, he became the editor for Geotimes, AGI's monthly geo-news magazine, as well as editor for AGI's annual Directory of Geoscience Departments. He also serves as co-author of EarthInquiry, an expanding series of geoscience exercise modules published through W.H. Freeman and Company.

DTM @ LPSC 2015

LPSC 2015

The 46th Lunar and Planetary Science Conference (LPSC) was held on 16-20 March 2015, at The Woodlands Waterway Marriott Hotel and Convention Center in The Woodlands, Texas. Eight scientists from DTM attended the conference this year, presenting talks and posters on a range of different topics.

This conference brings together international specialists in petrology, geochemistry, geophysics, geology, and astronomy to present the latest results of research in planeatary science. The five-day conference is organized each year by topical symposia and problem-oriented sessions.

New Electron Microprobe Installed on Carnegie's Broad Branch Road Campus

Electron Microprobe

A joint effort between DTM and the Geophysical Laboratory has led to the purchase of a new, state-of-the-art field emission electron microprobe.

The basic instrument was funded by a one million dollar grant by the Earth Sciences Division of the National Science Foundation (NSF). Additional attachments planned to be added in the future to the microprobe were funded by NASA.

New Mercury Surface Composition Maps Illuminate the Planet's History

Shoshana Weider

Two new papers from members of the MESSENGER Science Team provide global-scale maps of Mercury’s surface chemistry that reveal previously unrecognized geochemical terranes — large regions that have compositions distinct from their surroundings. The presence of these large terranes has important implications for the history of the planet.

Postdoc Spotlight: Cosmochemist Jemma Davidson

Jemma Davidson

The life of DTM NASA Associate Jemma Davidson revolves around old, lifeless rocks, thanks to her 9th grade geography teacher and a high school research paper.

Davidson had already resigned to become an accountant while sitting in her 9th grade geography class. But when her teacher accidentally dropped a volcanic rock he had collected during fieldwork, denting her wooden desk and releasing a sulfurous smell into the air, her aspirations changed. She was now determined to study geology.
