Extremely long waves could have initiated 2008 collapse events Depicting a cause-and-effect scenario that spans thousands of miles, a scientist at Scripps Institution of Oceanography at UC San Diego and his collaborators discovered that ocean waves originating along the Pacific coasts of North and South America impact Antarctic ice shelves and could play a role in their catastrophic collapse. Peter Bromirski of Scripps Oceanography is the lead scientist in a new study published in the journal...

Scientists have reported a giant iceberg over twice the size of Sydney Harbor is on a slow but steady collision course with Australia, according to the Telegraph UK. Researchers at the Australian Antarctic Division (ADD) spotted the 12 mile-long and 5-mile wide chunk of ice floating close to the mainland. The iceberg, known as B17B, is currently drifting 1,000 miles from Australia's west coast and is gradually moving north with the ocean current and prevailing wind. Should the...

Powerful westerly winds in the south Pacific have steered a flotilla of icebergs initially headed toward New Zealand to the east, away from the nation, according to an oceanographer at New Zealand's National Institute of Water and Atmospheric Research. A shipping alert was distributed last week while maritime authorities monitored the icebergs as they drifted from Antarctica toward New Zealand's South Island. "It looks like they've all disappeared east of New Zealand," oceanographer Mike...

A huge iceberg was identified near an island between Antarctica and Australia, an usual display in northern waters, Australian scientists announced on Thursday. Australian Antarctic Division researchers employed at Macquarie Island caught a glimpse of the iceberg last Thursday 5 miles away from the coast. The iceberg, which is 160 feet tall and 1,640 feet wide, is most likely a chunk that split from a bigger iceberg. The origin of the iceberg is guessed to be from Antarctica's Ross Ice...

U.S. scientists say a 24-foot-long robotic submarine will be used in a multimillion-dollar, five-year study of melting on the West Antarctic Ice Sheet. Northern Illinois University said its robotic submarine will be lowered through more than a half mile of ice into ocean water in the study that involves nine U.S. institutions. Researchers said the submarine will collapse to a width of only two feet, allowing it to be lowered through a drill hole melted in the ice. The sub is designed to allow...

The European Space Agency says satellite images show icebergs have begun to calve from the northern front of the Wilkins Ice Shelf in Antarctica. ESA scientists said the images indicate the huge shelf has become unstable following the collapse three weeks ago of the ice bridge that linked the Antarctic mainland with Charcot Island. That ice bridge, said the ESA, effectively formed a barrier pinning back the northern ice front of the central Wilkins Ice Shelf. It collapsed April 5, removing...

A segment of an Antarctic ice shelf about the size of New York City has fallen into the sea this month following an ice bridge collapse, scientists said Tuesday. Satellite images depict the collapse of an ice bridge that previously connected Charcot Island to Antarctica. The ice bridge apparently collapsed on April 5, removing about 330 sq km of ice, according to the European Space Agency. "As a consequence of the collapse, the rifts, which had already featured along the northern ice front,...

U.S. and British government researchers announced on Friday that climate change is quickly shrinking one Antarctic ice shelf, while another is disappearing and glaciers are melting faster than climate scientists originally predicted, Reuters reported. Scientists noted that the Wordie Ice Shelf, which has been disintegrating since the 1960s, is gone and the northern part of the Larsen Ice Shelf no longer exists. Since 1986, over 3,200 square miles have broken off from the Larsen shelf. U.S....

According to the UN Environmental Program, an enormous breakaway piece of Antarctica's ice shelf could amplify the already significant effects of global warming in the region. The 40-kilometer (25-mile) ice bridge "“ which was the Wilkins Ice Shelf's last bridge to the coast "“ has now completely broken off and can be seen in satellite images as a free-floating island of ice roughly the size of Jamaica. Before it starting melting in the early 1990's, Wilkins Ice Shelf had an area...

An ice bridge in the Antarctic, which linked a shelf of ice the size of Jamaica to two islands, has collapsed. According to scientists, the rupture provides further evidence that climate change is occurring in the region. Researchers also fear that the Wilkins Ice Shelf, located on the western side of the Antarctic Peninsula, could be on the brink of breaking away. The bridge was regarded by scientists as an important barrier holding the shelf structure in place. The removal of the bridge...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
