North Magnetic Pole could be leaving Canada

March 20, 2002 Posted: 5:52 PM EST (2252 GMT)

(CNN) -- The North Magnetic Pole
could soon abandon Canada, migrate
north of Alaska and eventually wind up
in Russia, according to a Canadian
scientist.

The magnetic pole, which has steadily
drifted for decades, has picked up its pace
in recent years and could exit Canadian
territory as soon as 2004, said Larry
Newitt of the Geological Survey of
Canada.

If the pole follows its present course, it
will pass north of Alaska and arrive in Siberia in a half century, but Newitt
cautioned that such predictions could prove wrong.

"Although it has been moving north or northwest for a hundred years, it is not
going to continue in that direction forever. Its speed has increased considerably
during the past 25 years, and it could just as easily decrease a few years from
now," the geophysicist said.

The erratic pole can jump around considerably
each day, but migrates on average about 10
kilometers to 40 kilometers each year.

Friend of navigators for centuries, beckoning
compass needles from virtually every point on
the planet, the North Magnetic Pole is distinct
from the North Terrestrial Pole, the fixed point
that marks the axis of the turning planet. The
magnetic pole is currently 966 kilometers (600
miles) from the geographic one.

Because the magnetic pole lies in the Arctic
Ocean, scientists attempting to pinpoint its
precise location must visit during a brief
window in the spring.

"We always do this kind of work in May. We
need frozen conditions so that we can land an
airplane anywhere on ice or snow, but not so
cold that it is impossible to work outdoors,"
Newitt said.

The North Magnetic Pole historically is
resurveyed about once every decade. But Newitt
and colleagues, who last studied the site in
2001, might attempt another trek in 2003 to
investigate further its accelerated migration.

The pole is a short plane ride away from
Resolute Bay, home to 200 hardy souls in one of
Canada's most northerly settlements, where a
popular T-shirt boasts: "Resolute is not the end
of the world, but you can see it from here."

Despite its remote location, tourists occasionally visit the town to experience North
Pole adventures, searching for everything from polar bears to Santa Claus to an
even more elusive target.

During a 1984 survey, Newitt and colleagues were approached by a newlywed
couple with a strange request.

"When they heard we were going to the pole they asked if they could hitch a ride.
When asked why they wanted to go there, they replied that they wanted to
conceive their child there," Newitt said.

The honeymooners did not make the trip, but other couples, also believing that the
location nurtures fertility, have chartered small planes to the forbidden spot, set up
tents on the ice and conducted their business.

Nothing about the magnetic field at the pole would have a significant effect on
humans, Newitt said. But ever the scientist, he added:

"It would be interesting to track the children of these polar trysts for the next
couple of decades."
