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.

Photo Essay: Monitoring Katla with Borehole Strainmeters

Iceland 2015

In June 2015, a team led by Alan Linde and supported by the Brinson Foundation travelled to the small town of Skógar situated close to the south coast of Iceland, about 15 kilometers from the Katla volcano, to install a borehole strainmeter

The team included DTM's Michael AciernoTyler Bartholomew, and Brian Schleigh, as well as Bergur Bergsson and Matthew Roberts of the Icelandic Meteorological Office (IMO). 

The purpose of installing a borehole strainmeter at this site was to monitor the Katla volcano. It is one of the largest volcanoes in Iceland, reaching a peak of 1,512 meters. Katla usually erupts every 40 to 80 years, however it's last violent eruption was over 98 years ago, in 1918. 

Stories from the Las Campanas Belles Blog: A Brief History of Stellar Women

Las Campanas Belles

"Tonight I'm observing at a different big telescope, Gemini North at Mauna Kea Observatory, Hawaii. But I wanted to share a great Explainer post by Dr. Amanda Bauer, a PhD Astronomer and Outreach Officer at the Australian Astronomical Observatory, that discusses spectroscopy. She was named one of Australia's "Top 5 Under 40” science researchers and communicators in March of 2015, and has written lots of blog posts about different aspects of astronomy. This one about spectroscopy caught my interest because 1) it's my craft, too, and 2) it's one of the things in astronomy, and science in general (the basic principles come from physics and chemistry), that I explain most often/enjoy explaining most.

However, there is a bit of history missing from Dr. Bauer's post that is important. Much of what I and MANY astronomers do today for our research -- using spectra to classify and learn about stars -- is thanks to some extremely smart and dedicated women scientists. Here's a bit (er, actually, a rather long bit) of history," says DTM Origins Fellow Johanna Teske in this blog post from the Las Campanas Belles blog on 20 July 2015.
