Canada to make groundbreaking Arctic claim

Randy Boswell, National Post Published: Wednesday, August 06, 2008

A year after Russian scientists planted their nation's flag on the North Pole seabed -- a controversial demonstration of their country's interest in securing control over a vast undersea mountain chain stretching across the Arctic Ocean from Siberia to Ellesmere Island and Greenland -- Canadian researchers have teamed with Danish scientists to offer proof that the Lomonosov Ridge is, in fact, a natural extension of the North American continent.

The completion of the study represents a key step in Canada's effort to eventually win rights over thousands of square kilometres of the polar seabed, a potential treasure trove of oil and gas being made more and more accessible as melting ice unlocks our High Arctic frontier.

A U.S. government geologic survey estimates that the Arctic holds some 90 billion barrels of oil and substantial gas reserves.

Canadian researchers have teamed with Danish scientists to offer proof that the Lomonosov Ridge is, in fact, a natural extension of the North American continent.

Along with Russia, both Canada and Denmark are preparing submissions under the United Nations Convention on the Law of the Sea (UNCLOS) to secure jurisdiction over large swaths of the Arctic Ocean sea floor adjacent to their coastlines.

But to secure those rights, each country has to submit scientific evidence proving the claimed undersea territories are linked geologically to its mainland or its Arctic islands

Canada's planned submission includes areas in the Beaufort Sea in the western Arctic, on the Lomonsov Ridge in the east and along another underwater Arctic mountain range in the central Arctic called Alpha Ridge

The study describes various geological traits

A Big Breakup in the Far North

Sam Soja, The Canadian Press / AP

Ice drifts off Canada's Ellesmere Island on Sunday after separating from the Ward Hunt Ice Shelf. The shelf lost a sheet of ice that covers seven square miles. A scientist said the cause was a "different climate" that isn't rebuilding Arctic ice, though he stopped short of directly blaming global warming.

Canadian Arctic sheds ice chunk

WE ARE DOOMED

Nearly 20 sq km (eight sq miles) of ice from the Ward Hunt shelf has split away from Ellesmere Island, according to satellite pictures.

It is thought to be the biggest piece of ice shed in the region since 60 sq km of the nearby Ayles Ice Shelf broke away in 2005.

Scientists say further splitting could occur during the Arctic summer melt.

The current warming being experienced in the Arctic means the conditions needed to rebuild the shelves simply does not exist.

Loss of ice in the Arctic, and in particular the extensive sea-ice, has global implications. The "white parasol" at the top of the planet reflects energy from the Sun straight back out into space, helping to cool the Earth

Further loss of Arctic ice will see radiation absorbed by darker seawater and snow-free land, potentially warming the Earth's climate at an even faster rate than current observational data indicates

The one take-home message for me here is that these ice shelves aren't re-generating

Paul Watson: 'There's no rest on planetary duty'

Paul Watson has devoted his life to fighting back against those who despoil the seas - but is he a prophet or a pirate? Tim Ecott meets a controversial crusader

Paul Watson doesn't stay on dry land very much. Last year the tireless eco-warrior was at sea for 50 weeks, and this year he has spent just one week at his home in Washington State. As he puts it: "There's no rest when you're on planetary duty."

Since forming Sea Shepherd in 1981, Watson, a former Canadian coast guard, has commanded more than 200 voyages aimed at stopping Antarctic and Arctic whaling, illegal long-line fishing in the Pacific, the killing of seals in Canada and, more recently, poaching and shark-finning in Galapagos.

Sea Shepherd has, in his words, "boarded and rammed more ships,

engaged in more high seas confrontations and sunk more ships than the Canadian navy"

Earth's poles long overdue for reversal

Earth's poles long overdue for reversal

SYDNEY: A reversal of the Earth's magnetic poles could happen sooner than we think, according to Dutch scientists who report that the planet's magnetic field is becoming gradually less stable.

A reversal could affect everything from navigation and communications equipment to the composition of the atmosphere, say experts.

The report, published today in the U.K. journal Nature Geoscience, found that reversals have been far more common in the last 200 million years than they were deep in the planet's history.

The magnetic poles wander around the vicinity of the geographic poles all the time – the north magnetic pole currently resides in the Canadian Arctic. However, at relatively regular intervals throughout the 4.5 billion year history of the planet, the magnetic poles have flipped completely. A few thousand years before a reversal, the magnetic field gradually gets weaker; something which could cause problems for inhabitants of the planet.

Vast cracks appear in Arctic ice

By David Shukman

Environment correspondent, BBC News

A Canadian expedition found the new cracks

Dramatic evidence of the break-up of the Arctic ice-cap has emerged from research during an expedition by the Canadian military.

Scientists travelling with the troops found major new fractures during an assessment of the state of giant ice shelves in Canada's far north.

The team found a network of cracks that stretched for more than 10 miles (16km) on Ward Hunt, the area's largest shelf.

The fate of the vast ice blocks is seen as a key indicator of climate change.

"It means the ice shelf is disintegrating, the pieces are pinned together like a jigsaw but could float away,"

Hot Times in the Arctic

clipper's remarks: Canada, the United States, Russia, Denmark, and Norway meet today in Greenland to negotiate sovereignty over the Arctic -- an issue that will continue to heat up as Arctic ice melts. One interesting ramification of the big melt: These countries will now have to start worrying about people and stuff coming in over their northern borders.

The High Arctic seabed is coveted for its potential oil and gas reserves, not just along the coast of Beaufort Sea but at the North Pole. Estimates put about 25 per cent of the world's remaining oil and gas reserves beneath the Arctic's ocean floor.

Energy firms have already begun exploring the waters off Greenland, while large deposits of gas are known to exist off the islands of the Canadian archipelago, as well as the coasts of the Northwest Territories and Alaska.

"There's an interest in those resources, but more immediate in the area is the fact that there will be more international shipping over the top of the world as the ice starts to melt," the CBC's Margo McDiarmid reported Tuesday from Ottawa.

The nautical journey from China to New York, for example, is 7,000 kilometres shorter if travelled across the Arctic waters over the top of the world rather than through the Panama Canal.

According to another scientist on the expedition

the new cracks fit into a pattern of change in the Arctic.

"We're seeing very dramatic changes; from the retreat of the glaciers, to the melting of the sea ice.

"We had 23% less (sea ice) last year than we've ever had, and what's happening to the ice shelves is part of that picture."

clipper's remarks: The Mars Reconnaissance Orbiter camera run showed the weather will be good on Sunday, with no significant dust storms around the landing site, said Phoenix principal investigator Peter Smith.

U.S. scientists will be joined by their counterparts from Canada and Europe in running the mission robotically from a headquarters in Tucson, Ariz. Canada's contribution is a Meteorological Station, or Met, designed to monitor changes in water abundance, dust, temperature and other variables in the Martian atmosphere.

Of 11 previous attempts to land spacecraft on Mars, only five have succeeded.

The Canadian Space Agency and a team headed by York University — and including contributions from the University of Alberta, Dalhousie University, the Geological Survey of Canada and instrument-maker Optech and — will oversee the science operations of the station, which was built by Canadarm maker MacDonald, Dettwiler and Associates Ltd., also known as MDA, of Richmond, B.C.

The Phoenix Mars Lander, which has a Canadian-built weather station aboard, is looking ready to make its landing on Sunday, according to NASA.

"All systems are nominal and stable," said Ed Sedivy, Phoenix spacecraft program manager for Lockheed Martin Space Systems, which built the spacecraft. "We have plenty of propellant, the temperatures look good and the batteries are fully charged."

The spacecraft will approach Mars at a speed of about 20,000 kilometres an hour and make the difficult descent, referred to by NASA officials as "seven minutes of terror," at about 7:45 ET on Sunday. When it enters the atmosphere, it will use superheated friction with the atmosphere, a strong parachute and a set of retrorockets to make its three-legged standstill touchdown on the surface, NASA said.

clipper's remarks: "During the day, the couple pulled the sled with the children inside, attempting to reach Hall Beach.

Meanwhile, ground crews began searching for the family on Sunday when they failed to arrive. It wasn't until Thursday that the weather lifted and a helicopter and airplane were able to join the search.

Bill Kennedy, a search co-ordinator in Repulse Bay, told The Canadian Press it was a group of Rangers -- mostly aboriginal military reservists -- who eventually found the family.

They followed a set of tracks that led to a burned-out snowmobile that the family appeared to have set on fire as a smoke signal to rescuers, CP reported. However, heavy cloud cover had made it impossible for rescuers to see the plume of smoke. "

A family of seven that spent six days lost in the Canadian Arctic survived by huddling inside a tent set up inside a makeshift igloo.

The family -- with five children under 12 -- was found safe Thursday, with the parents dragging a sled carrying their children.

None of the family members were injured in the ordeal.

They had been on a 250-kilometre trek, by snowmobile and sled, from Repulse Bay to Hall Beach, Nunavut when they took a wrong turn and got lost.

They had set out from Repulse Bay on May 1.

"We followed the tracks and we took a wrong turn," Merrill Siusangnark, the father, told CTV's Canada AM on Friday from Hall Beach.

"When I finally realized I didn't know the land that we were on, that we were in the wrong place, I tried to turn back to where I knew the land but my Ski-doo couldn't drag the komatik (sled)."
