We explore & discover

Scientists at the Department of Terrestrial Magnetism (DTM) bring the perspective of several disciplines to broad questions about nature. DTM's name comes from its original role to chart the Earth's magnetic field. This goal was largely accomplished by 1929. Since then, DTM has evolved to reflect the growing multi-disciplinary nature of the Earth, planetary, and astronomical sciences. Today, the historic goal remains to understand the physical Earth and the universe that is our home.

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.
