National Geographic News (December 15, 2005):

North Magnetic Pole Is Shifting Rapidly Toward Russia:

New research shows the pole moving at rapid clip—25 miles (40 kilometers) a year.

Over the past century the pole has moved 685 miles (1,100 kilometers) from Arctic Canada toward Siberia, says Joe Stoner, a paleomagnetist at Oregon State University.

North Magnetic Pole Moving East Due to Core Flux

north-pole-magnetic-russia-earth-core

Earth’s north magnetic pole is racing toward Russia at almost 40 miles (64 kilometers) a year due to magnetic changes in the planet’s core, new research says.

The core is too deep for scientists to directly detect its magnetic field. But researchers can infer the field’s movements by tracking how Earth’s magnetic field has been changing at the surface and in space.

Now, newly analyzed data suggest that there’s a region of rapidly changing magnetism on the core’s surface, possibly being created by a mysterious “plume” of magnetism arising from deeper in the core.

And it’s this region that could be pulling the magnetic pole away from its long-time location in northern Canada, said Arnaud Chulliat, a geophysicist at the Institut de Physique du Globe de Paris in France. Continue reading »

Dec. 16, 2008: NASA’s five THEMIS spacecraft have discovered a breach in Earth’s magnetic field ten times larger than anything previously thought to exist. Solar wind can flow in through the opening to “load up” the magnetosphere for powerful geomagnetic storms. But the breach itself is not the biggest surprise. Researchers are even more amazed at the strange and unexpected way it forms, overturning long-held ideas of space physics.

“At first I didn’t believe it,” says THEMIS project scientist David Sibeck of the Goddard Space Flight Center. “This finding fundamentally alters our understanding of the solar wind-magnetosphere interaction.”

The magnetosphere is a bubble of magnetism that surrounds Earth and protects us from solar wind. Exploring the bubble is a key goal of the THEMIS mission, launched in February 2007.

The big discovery came on June 3, 2007, when the five probes serendipitously flew through the breach just as it was opening. Onboard sensors recorded a torrent of solar wind particles streaming into the magnetosphere, signaling an event of unexpected size and importance.

“The opening was huge-four times wider than Earth itself,” says Wenhui Li, a space physicist at the University of New Hampshire who has been analyzing the data. Li’s colleague Jimmy Raeder, also of New Hampshire, says “1027 particles per second were flowing into the magnetosphere-that’s a 1 followed by 27 zeros. This kind of influx is an order of magnitude greater than what we thought was possible.”

Rapid changes in the churning movement of Earth‘s liquid outer core are weakening the magnetic field in some regions of the planet’s surface, a new study says.

“What is so surprising is that rapid, almost sudden, changes take place in the Earth’s magnetic field,” said study co-author Nils Olsen, a geophysicist at the Danish National Space Center in Copenhagen.

The findings suggest similarly quick changes are simultaneously occurring in the liquid metal, 1,900 miles (3,000 kilometers) below the surface, he said.

The swirling flow of molten iron and nickel around Earth’s solid center triggers an electrical current, which generates the planet’s magnetic field.

The study, published recently in Nature Geoscience, modeled Earth’s magnetic field using nine years of highly accurate satellite data.

Flip-Flop

Fluctuations in the magnetic field have occurred in several far-flung regions of Earth, the researchers found.

In 2003 scientists found pronounced changes in the magnetic field in the Australasian region. In 2004, however, the changes were focused on Southern Africa.

The changes “may suggest the possibility of an upcoming reversal of the geomagnetic field,” said study co-author Mioara Mandea, a scientist at the German Research Centre for Geosciences in Potsdam.
