Increased rainfall on the Antarctic Peninsula is rapidly melting glaciers like the Sheldon, which has recoiled 1.2 miles in 20 years and is raising world sea levels, a leading expert announced."Rain is very corrosive to glaciers and at least in part the reason this glacier is retreating," said David Vaughan, a British Antarctic Survey glaciologist."The glacier has retreated since 1989 and left this open water. That's the same pattern for 87 percent of 400 glaciers along the Antarctic...

Scientists say the Antarctic Peninsula's most fearsome land predator is a reddish bug called the Rhagidia mite. Although the continent is best known for penguins, seals and whales, the tiny mite is considered it's top predator. Now researchers are stepping up their study of these miniscule creatures in Antarctica for possible early warnings about how climate change may disrupt life around the planet in coming decades. Pete Convey, a biologist at the British Antarctic Survey, said Antarctica...

In an effort to seek clues to world ocean level rises in one of the most inaccessible places on earth, scientists are sending a yellow robot submarine to dive under an ice shelf in Antarctica. A U.S. research vessel will launch the 22 ft submarine to probe the underside of the ice at the end of the Pine Island glacier, which is moving faster than any other in Antarctica and already brings more water to the oceans than Europe's Rhine River. Large icebergs have been breaking off Antarctica's...

New rifts have developed on the Wilkins Ice Shelf that could lead to the opening of the ice bridge that has been preventing the ice shelf from disintegrating and breaking away from the Antarctic Peninsula. The ice bridge connects the Wilkins Ice Shelf to two islands, Charcot and Latady. As seen in the Envisat image here acquired on 26 November 2008, new rifts (denoted by colorful lines and dates of the events) have formed to the east of Latady Island and appear to be moving in a northerly...

Scientists from University of Edinburgh and the British Antarctic Survey said Thursday they will visit a vulnerable area of the Antarctic shelf later this year to determine if it might break apart and trigger a rise in sea levels in the coming years. The team will drill into the ice and use radars on the Larsen C ice shelf, located on the Antarctic peninsula nearest South America. In 1995, Larsen A, a chunk of the shelf, broke off. Another part, Larsen B, broke away in 2002. The remaining...

Over half of all colonies of penguins in Antarctica face a decline or total wipe out if the earth's temperature rises by just 2 degrees Celsius, a new report said on Thursday. "The problem is very serious. Antarctica and the Arctic are the most threatened regions from climate change," said Juan Casavelos, WWF's Antarctic Climate Change Coordinator. In the WWF report titled "2 deg C is Too Much" experts said unless nations slash carbon emissions, the world would warm by an average 2 deg C in...

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...

Wilkins Ice Shelf has experienced further break-up with an area of about 160 km² breaking off from 30 May to 31 May 2008. ESA's Envisat satellite captured the event "“ the first ever-documented episode to occur in winter. Wilkins Ice Shelf, a broad plate of floating ice south of South America on the Antarctic Peninsula, is connected to two islands, Charcot and Latady. In February 2008, an area of about 400 km² broke off from the ice shelf,...

A vast ice shelf hanging on by a thin strip looks to be the next chunk to break off from the Antarctic Peninsula, the latest sign of global warming's impact on Earth's southernmost continent. Scientists are shocked by the rapid change of events. Glaciologist Ted Scambos of the University of Colorado was monitoring satellite images of the Wilkins Ice Shelf and spotted a huge iceberg measuring 25 miles by 1.5 miles (41 kilometers by 2.5 kilometers) that appeared to have broken away from...

British Antarctic Survey has captured dramatic satellite and video images of an Antarctic ice shelf that looks set to be the latest to break out from the Antarctic Peninsula. A large part of the Wilkins Ice Shelf on the Antarctic Peninsula is now supported only by a thin strip of ice hanging between two islands. It is another identifiable impact of climate change on the Antarctic environment. Scientists monitoring satellite images of the Wilkins Ice Shelf spotted that a huge (41 by 2.5 km)...

Antarctic Silverfish, Pleuragramma antarcticum
2012-04-02 17:14:35

The Antarctic Silverfish, (Pleuragramma antarcticum), is a member of the Notothenioidei family of fish. It is widely distributed around the Antarctic, but has largely disappeared from the western side of the northern Antarctic Peninsula based on 2010 research funded by the National Science Foundation. It is also found throughout the Southern Ocean. It grows to an average size of 6 inches, but has been known to reach lengths of up to 10 inches. It is usually pink with a silver tint, and...
