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.

Over 84 Students Gather for the Second International Diamond School in Italy

International Diamond School 2015

Over 84 ‘students’, including master, Ph.D., postdoctoral and professional levels, from 18 different countries, gathered in the Italian Alps at the end of January for a unique international diamond school focused on training new diamond researchers and exposing individuals in the diamond industry to latest techniques.

The University of Padua hosted this program, titled “The Nature of Diamonds and Their Use in Earth’s Study”, from 27-31 January 2015, which was organized by DTM's Steven Shirey, Fabrizio Nestola (University of Padua) and Graham Pearson (University of Alberta) under the auspices of the Diamonds and the Mantle Geodynamics of Carbon consortium (DMGC) part of the Deep Carbon Observatory (DCO).

Peter Driscoll Joins DTM's Geophysics Staff

Carnegie News

DTM is pleased to announce that Peter Driscoll will join its geophysics staff in August 2015.

Driscoll received his Ph.D. degree in Earth and planetary science from Johns Hopkins University in 2010. Much of Driscoll's research is driven by the questions: what makes the Earth a unique planet? He says Earth is unique in that it is the only planet that has maintained a strong magnetic field, plate tectonics, and surface liquid water over most, and possibly, all of its history. What is it about Earth’s interior that has allowed these complex phenomena to occur? How do they work? Are they connected in any way?
