”œWhere has all the ice gone?” Joe Immaroitok asked. It was October 24, 2006, and he was staring at Foxe Basin. A shallow expanse of ocean the size of Lake Superior, the basin usually freezes over by early October, enabling the Inuit to travel across to Baffin Island to hunt caribou. This winter, the local council in Igloolik was considering chartering a plane to take the hunters across the unfrozen sea.

A few hours before I spoke with Immaroitok, I’d sailed through Fury and Hecla Strait on board the CCGS Amundsen, Canada’s research icebreaker. All we saw were a few chunks of thick, aquamarine ”œmultiyear” ice ”” formed when ice sur- vives one summer or more, and new ice accretes to it ”” which had floated down from higher latitudes and were eas- ily avoided. The previous day, we’d passed through Bellot Strait ”” the first ship ever to do so in October. We were 700 kilometres north of the Arctic Circle, but there was no ice.

The two straits are part of the Northwest Passage, the so- called Arctic Grail. From Martin Frobisher in 1576 to John Franklin in 1845, generations of European explorers searched for a navigable route through the Arctic islands to Asia. Many of them ”” including Franklin and his men ”” died in the attempt. Their greatest challenge was sea-ice, which has almost always filled the straits, even in summer. William Parry spent the summers of 1821 and 1822 waiting for the ice to clear from Fury and Hecla Strait. But though the strait is named after his ships, he never made it through. Leopold McClintock, despatched by Lady Franklin to search for her husband on King William Island, tried six times to penetrate Bellot Strait during the summer of 1858 before continuing his journey by dog-sled. It took Roald Amundsen three years ”” including two winters lodged in the ice ”” to complete the first full transit of the Northwest Passage in 1906.

In 2004, the Arctic Climate Impact Assessment reported that the average extent of sea-ice cover in summer had declined by 15-20 percent over the previous 30 years. The remaining ice was 10-15 percent thinner overall and 40 percent thinner in the middle of the Arctic Ocean. These trends are expected to accelerate, so that by the end of the 21st century, there might be no sea-ice at all in the summer. Recent satellite measure- ments analysed by the US National Snow and Ice Data Center are even more alarming. In March 2006 the area covered dur- ing the winter by sea-ice was at an all-time low: 300,000 attempt. Their greatest challenge was sea-ice, which has square kilometres less than the previous year. At this rate, the Arctic could lose all of its sea-ice by 2030.

Phytoplankton in the Arctic, like all plants, remove carbon dioxide from the atmosphere by photosynthesising. Because the waters they live in are so cold, when the phytoplankton die they sink into the ocean depths without decomposing: the carbon they have removed from the atmosphere remains at the bottom of the sea for hundreds of years. Jody Deming from the University of Washington, who was on board the Amundsen with me, is worried that as the water warms up the activity of marine bacteria that feed on the dead plankton will increase, releasing carbon dioxide back into the atmosphere.

Gary Stern from the Canadian Department of Fisheries and Oceans, who was also on the ship, is studying mercury levels in Beluga whales, which have been rising far more steeply than can be explained solely by the contami- nant being carried on the wind from industrial sources further south. One possible explanation is that, as the per- mafrost melts, naturally occurring mer- cury leaches out of the soil and into the sea, where it is carried up the food chain.

Climate change is having more immediately apparent effects on other Arctic mammals. In Queen Maud Gulf, we encountered the only ”œfirst-year” ice of our voyage ”” as well as our only polar bear. The bear was thin and, as he walked, his hind feet kept breaking through the ice. But he will have made it through the winter, since he is now able to catch ring seals. Further south, where the ice-free season is even longer, other polar bears are less lucky. In Hudson Bay, the bears’ birth rate is plummeting as lengthening summers impose famine- like conditions on a species that has evolved to hunt seals on ice.

Off Cape Felix, near where Franklin died, the ship stopped alongside a multi- year ice floe the size of a hockey rink to extract an ice-core: a cylindrical cross- section cut out with a hand-powered auger. The ice contains microbes able to withstand temperatures as low as -35°C. The way they do this, once it is fully understood and synthesised, could have important medical applications. As we arrived, an Arctic fox, snow-white and no bigger than a cat, scampered behind a small ridge. In previous years, the fox would not have been stranded, appar- ently without food, because first-year ice would already have formed across the surface of the ocean.

With the ice disappearing, the cur- rents and narrow channels pose less of an impediment to navigation: an experienced sailor could now take a large tanker through the straits during the late summer and early autumn. Governments are gradually waking up to this new reality. In 2001, a report pre- pared for the US Navy predicted that ”œwithin five to ten years, the Northwest Passage will be open to non-ice- strengthened vessels for at least one month each summer.” A briefing given to the Canadian defence minister, Gordon O’Connor, in February 2006 was confident that ”œthe Northwest Passage could be open to more regular navigation by 2015” if ”œthe current rate of ice thinning continues.”

Shipping companies are also watch- ing closely. A navigable Northwest Passage offers a route between Asia and the Atlantic seaboard that is 7,000 kilo- metres shorter than the one through the Panama Canal ”” saving on time, fuel and transit fees. In the short term, uncer- tainties about the weather, the availabil- ity of search and rescue, and the movement of multiyear ice will ”” along with higher insurance premiums ”” dis- suade reputable companies. But less reputable ones might take the risk. There are quite a few rusting tankers with Liberian flags and disgrun- tled creditors sailing on the world’s oceans.

International shipping in the Arctic carries with it serious environmental risks. An oil spill would cause catastrophic damage. Large ships empty- ing their ballast tanks as they entered these shallow waters could introduce destructive new species, such as fish parasites or poisonous algae.

These dangers are of great concern to the Inuit. When I asked Maria Kripanik, the deputy mayor of Igloolik, about the possibility of increased ship- ping through the Northwest Passage, her first thought was for ”œour animals.” The waters of Foxe Basin, she explained, are home to whales, seals and walrus, which the Inuit depend on for food. There are also security con- cerns. The police and military presence in the region is relatively light, which could make it attractive for ships carry- ing illicit cargoes. Smugglers, illegal migrants, even terrorist groups might see an ice-free Arctic as a back door to North America. Cruise ships are already frequent visitors. The Kapitan Khlebnikov, a Russian-flagged converted icebreaker, offers luxury trips through the Northwest Passage. The Canadian Coast Guard’s 2005 Arctic Traffic Summary lists another six cruise ships and eight pleasure-craft as visitors to the Canadian Arctic that year.

The greatest incentive for future shipping, however, is the presence of substantial deposits of oil and gas. The US Geological Survey estimates that 25 percent of the world’s undiscovered fossil fuels are located under the Arctic Ocean. Big Oil is already planning against the day when they are discov- ered: Shell has recently commissioned an analysis of the legal status of the passage, which is the subject of a long- standing international dispute.

Ownership of the islands along the passage is not at issue. They were assigned to Canada by Britain in 1880, and the resulting title has never been contested. As for the straits and chan- nels between the islands, the nearly impenetrable ice meant that for decades the issue of ownership and control was never discussed. Only the development of powerful icebreakers ”” and now climate change ”” has brought the issue to the fore.

Canada claims that the passage constitutes Canadian internal waters. In 1986, it drew ”œstraight baselines” around its Arctic islands. Under inter- national law, straight baselines may be used to link the outer headlands of an archipelago or fragmented coastline. Provided the lines are of a reasonable length, the straits and channels with- in them are then subject to the full force of the coastal state’s domestic laws. Canada argues that its baselines are consolidated by historic usage, including the occupation of the sea- ice by the Inuit.

The United States insists that the passage is an ”œinternational strait”: a waterway connecting two expanses of high seas that is used for international navigation. The coastal state retains title to the waters, but foreign vessels have a right of ”œtransit passage,” much like walkers on a footpath through British farmland. Since straight base- lines cannot be used to close off an existing international strait, the crux of the dispute concerns the requirement that the strait be used for international navigation. In the past century, only two vessels have openly passed through the Northwest Passage without asking Canada’s permission: a US-owned ice- strengthened tanker in 1969 and a US Coast Guard icebreaker in 1985. Some submarine voyages have almost certain- ly taken place but the passage of a sub- marine, because it is covert, can’t create a new right under international law.

Ottawa argues that two transits can- not create an international strait. Washington points to a judgment of the International Court of Justice, in a case concerning the Corfu channel, which suggests that the volume of traffic is irrelevant. The US position has received some support from the European Commission, which in 1986 joined the State Department in protesting against Canada’s drawing of straight baselines. More unauthorized transits would seri- ously undermine Canada’s claim. Yet Canada is poorly equipped to prevent them. The bulk of its military presence is provided by the Canadian Rangers, 1,400 part-time volunteers, many of them Inuit, who live in 59 hamlets stretching from Baffin Island to the Alaskan frontier. They are not trained or equipped to stop ocean-going vessels.

The Canadian Coast Guard’s small fleet of icebreakers is inca- pable of operating in the Northwest Passage in winter, and is redeployed to the Gulf of St. Lawrence each autumn. The ships are also growing old: the largest, the Louis St. Laurent, was built in 1969; the Amundsen is just a decade younger. If Canada is to control the passage, it will need ships that can go any- where, at any time.

Before being elected prime minister in January 2006, Stephen Harper promised ”œthree new armed naval heavy icebreakers.” Now he is hesitating. The icebreakers were not mentioned in his first budget, and did not feature in a $17.1 billion defence procurement package announced last June. Perhaps he has realized that it would be better if the new vessels were supplied to the Coast Guard, which uses its icebreakers to clear paths for other ships, provide search and rescue, support research scientists and help in the enforcement of fish- ing and environmental regulations as well as customs and criminal law. With the addition of light armaments and a few police or military person- nel, they could also play an enhanced security role.

Harper’s indecisiveness is all the more unfortunate, because US interests have changed. During the Cold War, the United States was focused on maintain- ing open access for its navy, and especial- ly its submarines. Under the law of the sea, submarines may pass through an international strait without surfacing or otherwise alerting the adjacent coastal state or states, something not permitted in internal waters. From Washington’s perspective, the Canadian claim threat- ened to create an inconvenient prece- dent for straits and channels elsewhere.

Today, Washington is more con- cerned about terrorists sneaking into North America, or rogue states using the oceans to transport WMD. And these challenges would best be addressed through a domestic legal system’s criminal, customs and immi- gration laws, rather than the much looser constraints of international law. The Canadian system is the only domestic legal system that could plau- sibly be applied in the Northwest Passage. In the circumstances, it does- n’t benefit the United States ”” or most other countries ”” to have foreign ves- sels shielded from reasonable regula- tions and scrutiny by maintaining that the passage is an international strait.

Access to the waterway is not real- ly in question, since Canada would be very unlikely to deny entry to one of its allies, or indeed to a reputable ship- ping company. As Pierre Trudeau said in 1969, ”œto close off those waters and to deny passage to all foreign vessels in the name of Canadian sovereignty… would be as senseless as placing barri- ers across the entrances of Halifax and Vancouver harbours.” Washington’s concern about an inconvenient precedent is also misplaced. It can plausibly be argued that the near absence of international navigation to date has created a situation where the passage can be distinguished from the other waterways that the US argues are international straits.

In March 2005, then-US ambassador Paul Cellucci revealed that he had asked the State Department to take a ”œseri- ous look at our longstanding pol- icy” on the Northwest Passage. This has created an opportunity to resolve the dispute. The Canadian government should seize the initiative by offering to provide open access for all US government vessels, facilitate shipping by reputable compa- nies, and invest in the equip- ment necessary to police the passage on a year-round basis ”” in return for the United States recognizing Canada’s claim. Having seen almost no ice in late October, it’s clear to me that we’ve no time to waste.
