Giant sheets of ice totaling almost 8 square miles broke off an ice shelf in the Canadian Arctic last week, and more could follow this year, scientists said Tuesday. The ice broke away from the shelf on small Ward Hunt Island, just off giant Ellesmere Island in one of the northernmost parts of Canada. It was the largest fracture of its kind since the nearby Ayles ice shelf, which measured 25 square miles, broke away in 2005.

Ten-year-old Sydney Simons never knew much about marine life, the Arctic or polar bears. And she's never been to SeaWorld in San Diego. So, SeaWorld came to Sydney and about 470 other children at Justice Street Elementary School on Tuesday. Although they didn't see any live animals, SeaWorld's presentation, "Arctic Animals," made a big splash with students. "It was really neat to hear about all the animals, but I want to see them live, now," said Sydney, a fifth-grader.

The Bush administration's authorization of a major new offshore oil drilling program in the Arctic Ocean was dealt a serious setback Thursday when a federal appeals court ruled the plan did not adequately consider the effect on bowhead whales and the native villagers who make their living from the frigid coastal waters. Ruling on the first of several major new projects for tapping oil and gas deposits from the Arctic floor, the U.S.

Spring begins eight days earlier in the Arctic than it did a decade ago, according to satellite measurements of vegetation coverage. The measurements suggest that plant cover appears earlier in the year, grows lusher and sticks around longer in northern climes than it used to. The finding, reported in the April 17 Nature, confirms a phenomenon first reported last year and may be an indication of global warming.

Federal researchers have discovered that shrubs in the Alaskan Arctic are growing larger and spreading across previously barren territory in the tundra. The findings, reported in Thursday's Nature, add to the scientific consensus that the region is gradually getting warmer. The team combed through archives of aerial photos, comparing new images to those of the same locations taken 50 years ago.

The thinning ozone layer over the Arctic may be headed for even more dramatic losses because of global warming, according to research that will be presented Wednesday at the American Geophysical Union meeting in Washington, D.C. Currently, ozone depletion is much more severe over the Antarctic, where there is a hole in the ozone layer.

There was less sea ice in the Arctic on Friday than ever before on record, and the melting is continuing, the National Snow and Ice Data Center reported. "Today is a historic day," said Mark Serreze, a senior research scientist at the center in Boulder, Colo. "This is the least sea ice we've ever seen in the satellite record, and we have another month left to go in the melt season this year."

The Arctic's perennial sea ice lost an area the size of Texas last year, in a change that may have an effect on the environment and marine transport, NASA said. About 288,000 square miles of perennial ice, which normally doesn't melt during the summer, was lost from 2004 to 2005, scientists found using data from NASA's QuickScat satellite. Perennial sea ice can be 10 or more feet thick, according to NASA.

In an attempt to head off a major commercial fishing march into the Arctic, the Obama administration declared a moratorium on expanded fishing in the still-uncharted waters of the far north. U.S. Commerce Secretary Gary F. Locke banned the expansion of most commercial fishing beyond the Alaskan coast until new scientific studies can determine what fish stocks exist and how crucial they are to maintaining a fragile Arctic ecosystem already under stress. The order, recommended by the North Pacific Fisheries Management Council in February, restricts future commercial fishing for finfish and shellfish in nearly 200,000 square miles of the Beaufort and Chukchi seas.

Scientists who have been analyzing data from a series of 14 flights over the North Pole by instrument-laden aircraft have concluded what many had feared: that the ozone layer over the Arctic is thinning, although not nearly as severely as over Antarctica. The scientists reported in last week's issue of Nature that ozone depletion ranged from 12% to 35% within the north polar region, and they suggested that man's release of chlorofluorocarbons has caused the loss.
