Geomedia: Music: The sounds of the sea

At the ocean’s edge, the crash of waves against the shore is a familiar sound. It might be rhythmic, but it’s not particularly melodious. There are, however, a few spots around the world where the tides, waves and wind make actual music, thanks to acoustic man-made structures that use the movements of seawater to produce sound. Currently, three of these so-called tidal organs have been built, one each in Croatia, England and the United States.

Geomedia: Performance: Bella Gaia is a show in orbit and Earth is the star

On the screen, images of the far reaches of the cosmos — galaxies, stellar nebulae and supernovae — loom high over a stage. The words, “The Living Universe,” appear and the view zooms in: first on our galaxy, then on our solar system and, finally, on Earth. Bella Gaia, a live performance piece featuring dance and music set in front of a large projection-screen displaying images of Earth from space, begins.

Down to Earth With: Geophysicist Julian Lozos

Julian Lozos, a postdoctoral researcher affiliated with both the U.S. Geological Survey and Stanford University, designs computer models that simulate earthquakes. As a graduate student at the University of California at Riverside (UC Riverside), Lozos discovered part of what makes the San Jacinto Fault — a major fault in Southern California underlying the homes of millions — tick. For this work, Lozos received the Outstanding Student Presentation award at the annual meeting of the Seismological Society of America three years in a row, an unprecedented accomplishment.

Musical magnetic reversals

Although Earth’s magnetic field currently points toward the North Pole, the planet’s magnetic dipole flips direction every few hundred thousand years or so. Engebretson tracked the last 85 million years of these magnetic reversals, with higher pitches representing shorter polarities (a period of time when the direction of the magnetic field stays the same), and lower pitches longer ones.

Earth tides in A major

Earth experiences small, millimeter-sized tides, called Earth tides. Using a dataset from NASA’s Jet Propulsion Laboratory in California from A.D. 1600 to A.D. 2200, Engebretson calculated the net gravitational force of the sun and the moon at particular intervals and then mapped them onto the A major scale.

Down to Earth With: Marc Kuchner

Marc Kuchner likes to joke that when he feels sociable at a party, he tells fellow guests that he is an astronomer. But when he wants to be left alone, he says, he tells them he is an astrophysicist. At NASA’s Goddard Space Flight Center in Greenbelt, Md., Kuchner spends his time thinking about planets outside the solar system and looking for ways to better see them — and he’s devoted some of his time to working on the Terrestrial Planet Finder, a proposed NASA mission to look for and image Earth-like exoplanets. For his work on improving the detection and understanding of exoplanets, SPIE, an international society that advances light-based research, awarded him the group’s Early Career Achievement Award earlier this year.
