The International Ice Charting Working Group predicts more marine transportation in the Arctic as sea ice continues to diminish and warns of "significant hazards to navigation," according to a statement released yesterday.
The statement was released during a five-day conference held at ESRIN, ESAs Earth Observation Centre in Frascati, Italy, in which operational ice experts from Europe and North America gathered to discuss the state of the polar regions.

A new technique to track changes in the extent of Arctic sea ice over the past 1,000 years is being developed by a UK team from the University of Plymouth.
The scientists are studying sediments from the sea bed in the fabled Northwest Passage.
These muds may cast valuable historical light on why some famous expeditions to the region were successful while others were doomed to failure.
The research could also guide computer forecasts of future climate.

Miles beneath the 3-foot ice packs of the Arctic Ocean, biologist Tim Shank got his first-ever glimpse of the sea floor.
It looked nothing like what he thought.

"We're miles below the surface and it's completely different than what we expected, because we saw lava formations that you'd see on Hawaii or on mid-ocean ridges that erupted eight to 10 years ago. This again proves that we know so little about our deep ocean" - Tim Shank, who was part of an international team of scientists who took part in a summer expedition to the Arctic.

The giant Ayles Ice Island drifting off Canada's northern shores has broken in two - far earlier than expected.
In a season of record summer melting in the region, the two chunks have moved rapidly through the water - one of them covering 98km (61 miles) in a week.
Their progress has been tracked amid fears they could edge west towards oil and gas installations off Alaska.
The original Manhattan-sized berg (16km by five km) - broke off the Ayles Ice Shelf in 2005.

Scientists monitoring the Arctic say the sea ice appears to be growing again after undergoing a record retreat.
The US National Snow and Ice Data Centre said the minimum extent of 4.13 million sq km (1.59 million sq miles) was reached on 16 September.
The figure shatters all previous satellite surveys, including the previous record low of 5.32 million sq km measured in 2005.
Earlier this month, it was reported that the Northwest Passage was open.

A Russian expedition has proved that a ridge of mountains below the Arctic Ocean is part of Russia's continental shelf, government officials have said.
The Natural Resources Ministry said tests on soil samples showed Russia was linked to the Lomonosov Ridge.
Moscow has mounted several expeditions recently - and risked tensions with rivals in August by planting a flag in the seabed below the North Pole.

Russian geologists have revealed preliminary results that the structure of the underwater Lomonosov mountain chain is similar to other continental shelves.
This finding would allow Russia to claim 1.2 million sq km of the Arctic region.

"Preliminary, September 20, results of an analysis of the Earth's crust show that the structure of the underwater Lomonosov mountain chain is similar to the world's other continental shelves, and the ridge is therefore part of Russia's landmass" - Natural Resources Ministry.

Researchers with Russia's Oceanology research institute had conducted deepwater seismic and geophysical surveys, of the Mendeleyev underwater chain in 2005, and to the Lomonosov ridge in the summer 2007.

The ministry would provide final research results in December 2007.

The most direct route through the Northwest Passage has opened up fully for the first time since records began, the European Space Agency (Esa) says.
Historically, the passage that links the Atlantic and Pacific Oceans through the Canadian Arctic has been ice-bound.
But the agency says ice cover has been steadily shrinking, and this year's drop has made the passage navigable.
The findings - based on satellite images - have raised concerns about the speed of global warming.

Vast ice island stuck in Arctic
An island of ice the size of Manhattan has drifted into a remote channel and is now jammed by pack ice.
The Ayles Ice Island changed the Arctic map by breaking free from the Canadian coast two years ago.
Scientists have been tracking the progress of this monster iceberg amid fears that it could edge west towards oil and gas installations off Alaska.
The creation of the island is seen by many scientists as a key indicator of the rapid warming of the Arctic.
