A U.S.-led study has found climate change on the Antarctic Peninsula -- one of the most rapidly warming spots on Earth -- is now affecting microscopic life. Researchers using detailed satellite data have discovered global warming is not only affecting just the penguins at the top of the food chain, but simultaneously life at the base of the ecosystem. The researchers from the National Science Foundation's LTER -- Long Term Ecological Research program -- led by Hugh Ducklow of the Marine...

Scientists have long established that the Antarctic Peninsula is one of the most rapidly warming spots on Earth. Now, new research using detailed satellite data indicates that the changing climate is affecting not just the penguins at the apex of the food chain, but simultaneously the microscopic life that is the base of the ecosystem. The research was published in the March 13 edition of Science magazine by researchers with the National Science Foundation's (NSF) LTER (Long Term Ecological...

On Antarctic research bases, chefs rely on imported and often frozen food in order to feed crewmembers. The 1959 Antarctic Treaty sets aside the continent as a nature reserve devoted to peace and science and bases have, over the years, stopped eating fresh wildlife. Fresh seal brains, penguin eggs or grilled cormorant were once considered the "delicacies of the Antarctic," but are now off the menu. "You have to use what you've got in the store. Frozen stuff, tinned stuff and if you're really...

The Antarctic Peninsula juts into the Southern Ocean, reaching farther north than any other part of the continent. The southernmost reach of global warming was believed to be limited to this narrow strip of land, while the rest of the continent was presumed to be cooling or stable. Not so, according to a new analysis involving NASA data. In fact, the study has confirmed a trend suspected by some climate scientists. "Everyone knows it has been warming on the Antarctic Peninsula, where there...

A large ice shelf is near collapse in Antarctica, held together only by a small strip of ice as global warming continues to alter the map of the frozen continent. "We've come to the Wilkins Ice Shelf to see its final death throes," glaciologist David Vaughan of the British Antarctic Survey (BAS) told Reuters after his red Twin Otter plane landed near the shelf's narrowest section. "It really could go at any minute," he said, adding that the ice bridge could linger weeks or months. The large,...

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...

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...
