Federal officials confirm 10 polar bears, an unusually large number, have recently been seen swimming in open Alaskan waters. Arctic ice melts in the Chukchi Sea are the suspected cause of the bears swimming toward either land or more remote icebergs, The New York Times reported Saturday. Such sightings were rare until 2004 but have grown more common as polar bears hunt for seals. "It's not unusual for bears to be swimming," said Susanne Miller, a biologist with the Fish and Wildlife...

Scientists in Britain have discovered a new global warming threat to marine life in Antarctica -- breakaway icebergs that destroy any life in their path. Shallow habitats of species such as giant sea spiders, Antarctic worms, sea urchins and corals face growing risk from icebergs as they tear up the sea floor, The Times of London reported Friday. The findings indicate climate change risks go beyond rising ocean temperatures, the British Antarctic Survey team said. Although near-shore...

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, ESA's 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. "In September 2007, the Arctic sea...

WELLINGTON, New Zealand -- An iceberg has been spotted from the New Zealand shore for the first time in 75 years, one of about 100 that have been drifting south of the country. The giant ice chunk was visible Thursday from Dunedin on South Island but has since moved away, driven by winds and ocean currents. The flotilla of icebergs - some as big as houses - were first spotted south of New Zealand early this month. Last year, icebergs were seen in the country's waters for the first time in 56...

CHICAGO (UPI) -- U.S. scientists say a severe storm in the Gulf of Alaska in October 2005 generated an ocean swell that six days later broke apart a giant iceberg. The team of scientists -- led by Professors Douglas MacAyeal of the University of Chicago and Emile Okal at Northwestern University -- said the swell was so powerful it destroyed the iceberg near the coast of Antarctica, more than 8,300 miles away. "We are reporting on a unique kind of seismological signal picked up by seismometers...

BERLIN (Reuters) - Scientists monitoring earth movements in Antarctica believe they have found a singing iceberg. Sound waves from the iceberg had a frequency of around 0.5 hertz, too low to be heard by humans, but by playing them at higher speed the iceberg sounded like a swarm of bees or an orchestra warming up, the scientists said. The German Alfred Wegener institute for polar and marine research publish the results of its study, done in 2002, in Science magazine on Friday. Between July...

ESA -- After five years of being the world's largest free-floating object, the B-15A iceberg has broken into smaller pieces off Antarctica's Cape Adare. ESA's Envisat satellite's Advanced Synthetic Aperture Radar (ASAR) is sensitive to ice, and has been tracking the movement of the drifting ice object continuously since the beginning of this year. Its latest imagery reveals the bottle-shaped iceberg split into nine knife-shaped icebergs and a myriad of smaller pieces on 27-28 October,...

A multifaceted research effort by scientists at Scripps Institution of Oceanography at the University of California, San Diego, and their international colleagues from the University of Tasmania and the Australian Antarctic Division, has resulted in several important new findings about Antarctica and the changing dynamics of its ice structure. Scientists have been investigating the mechanisms by which Antarctic icebergs detach from the main continental ice sheet because of the importance of...

ESA -- The mammoth B-15A iceberg appears poised to strike another floating Antarctic ice feature, a month on from a passing blow that broke off the end of the Drygalski ice tongue. As this Envisat image reveals, this time its target is the ice tongue of the Aviator Glacier. First discovered in 1955, and named to mark the work done by airmen to open up the Antarctic continent, the Aviator Glacier is a major valley glacier descending from the plateau of Victoria Land along the west side of...

ESA -- Maps of Antarctica need to be amended. The long-awaited collision between the vast B-15A iceberg and the landfast Drygalski ice tongue has taken place. This Envisat radar image shows the ice tongue "“ large and permanent enough to feature in Antarctic atlases - has come off worst. An image acquired by Envisat on 15 April 2005 shows that a five-kilometre-long section at the seaward end of Drygalski has broken off following a collision with the drifting B-15A. The iceberg itself...
