E21 – X-rays of the Earth’s Gooey Center
Much like x-rays can show broken bones (or noses), seismic equipment can show us what’s going on in Earth’s interior. While seismologists can’t take quick snapshots like medical doctors can, they can provide an image of tectonic plate movements over time to help the scientific community – and local communities – understand geophysical phenomena from mountain formations to volcanoes to the earthquakes that rock their world.

E19 – Eavesdropping on the Ocean
To those of us on land, the world underneath the oceans seems quiet and serene. But scientists who study ocean acoustics will tell you it is anything but tranquil underwater. Our oceans are home to a cacophony of sounds – from the songs of marine mammals to the cracking of icebergs to the rumbling of earthquakes to the roar of ships.

E16 – Gunslingers of the Sea
Snapping shrimp are small but mighty creatures: they’re only a few inches long but are among the noisiest animals in the ocean. The loud cracking noise they make when snapping their claws sounds almost like a gunshot, and when enough shrimp snap at once, the din can be louder than the roar of a passenger jet flying overhead.
Third Pod from the Sun is the American Geophysical Union’s podcast about the scientists and methods behind the science. These are stories that you won’t read in a manuscript or hear in a lecture.
