About this episode
The ocean doesn't just cover the Earth.
It can make the entire planet vibrate.
Far below the surface, enormous waves and powerful movements of water create pressure variations that travel through the ocean and interact with the seafloor and the Earth itself.
The Ocean Makes the Whole Earth Ring Like a Bell explores the surprising connection between ocean waves, atmospheric pressure, seismic signals, and the subtle vibrations that constantly move through our planet.
Large ocean waves don't behave like ordinary waves at the beach.
As waves travel across deep water, they generate pressure fluctuations that can extend far below the surface. Powerful ocean systems can produce signals that reach instruments thousands of miles away.
Some of these signals are so subtle that humans cannot feel them.
Sensitive scientific instruments can detect them.
Scientists have found that ocean activity contributes to a continuous background of vibrations sometimes described as the Earth's "hum."
Storms, waves, tides, and interactions between the ocean and seafloor all contribute to this complicated planetary soundtrack.
The effect is especially fascinating during major storms.
Large waves interact with each other and with the seafloor, producing pressure signals that can travel through the ocean and into the solid Earth.
Seismometers can detect some of these signals even when there is no earthquake.
This gives scientists another way to study the ocean.
Instead of relying only on satellites, buoys, ships, and underwater instruments, researchers can also listen to the vibrations generated by the ocean itself.
The planet is never completely still.
Winds move through the atmosphere.
Waves cross the oceans.
Tides pull enormous masses of water.
The ground responds.
And sensitive instruments record the result.
The ocean is constantly moving energy around the planet—and some of that energy becomes part of Earth's faint, continuous vibration.
So when you imagine the Earth from space, don't picture a silent sphere.
Picture an enormous planet surrounded by moving water, atmosphere, and energy.
A planet that is never truly quiet.
A planet that, in a very real sense, is always ringing.
The Ocean Makes the Whole Earth Ring Like a Bell.
