'Completely new' type of magnetic wave found surging through Earth's core

Scientists have detected a completely new type of magnetic wave that surges through Earth's outer core every seven years, warping the strength of our planet's magnetic field in the process.

The waves — dubbed "Magneto-Coriolis" waves because they move along the Earth’s axis of rotation, per the Coriolis effect — creep from East to West in tall columns that can travel up to 930 miles (1,500 kilometers) per year, the researchers wrote in a March 21 paper in the journal Proceedings of the National Academy of Sciences. Using a fleet of European Space Agency (ESA) satellites, the team pinpointed the mysterious waves to the outermost layer of Earth's liquid outer core, right where that layer meets the rocky mantle — roughly 1,800 miles (2,900 km) below the planet's surface.

According to the researchers, the existence of these waves could help explain mysterious fluctuations in the planet's magnetic field, which is generated by the movement of liquid iron in the planet's outer core. Satellite measurements of the magnetic field taken over the last 20 years show that the field's strength dips every seven years or so, coinciding with the oscillations of these newfound waves.

The source of these waves remains a mystery for now, but they likely stem from "disturbances deep within the Earth's [outer] core," Gillet said.

It's also likely that these waves aren't the only ones oscillating through the core-mantle boundary, Gillet added. While the Magneto-Coriolis waves explain some of the seven-year magnetic field fluctuations observed by Swarm and other sensors, other as-yet-undiscovered waves with even longer periodicities could account for magnetic field variations on longer timescales, Gillet said. To discover such waves, researchers will just have to keep the...

If I was Earth’s core, I’d be disturbed too.

As sensor technologies get finer and more sensitive, who knows what planet endangering theories will emerge.

Global warming causes gravitational magnetic perturbations. Or something.

Let's block it and see what happens!

We’re all going to fall off!!!

Or maybe it’s a good thing so that we don’t fall off.

Back to chores.

not ‘new’ to God.

keep trying to measure, but you’ll never ‘know’ the full extent of the ‘...foundations of the earth.’

Idiots keep blaming earth’s changing climate on man when we don’t even know what is going on in the center of the earth. We have no clue why climate changes. None.

With just the right surfboard, catching that wave would be an awesome ride...

“We have no clue why climate changes. None.”

Speak for yourself.

Here’s some (non-global warming hoax) homework:

What’s a Forbush decrease?

What does the relative level of galactic radiation at certain altitudes have to do with cloud nucleation on earth?

How does the Sun protect (or not protect) us from galactic radiation, such as gamma rays?

I do sometimes wonder how many different long -> ultra-long cycles there are out there and how they may affect us?

I would agree the more we learn, the more questions we have, and the more we realize we don’t know.

However, we do have a clue as to the later states of climate and weather development.

But the funny part is the more we discover, the more remote we human’s become from the real climate calculus and science.

It’s laughable !

Is there a mysterious island on top of it?

The molten iron core rotation may coincide with the mantle, so for a time there is a measurable difference. If they both rotated at the same speed, we would not be here.
