Antarctic Ice Shelf Collapse Has Been Occurring For 600 Years, Manmade Climate Change Is Now Adding To Problem
2012-08-23 10:53:35

Lawrence LeBlond for redOrbit.com - Your Universe Online The Antarctic Peninsula has been continually shrinking for centuries, since long before the Industrial Revolution, according to an international team of researchers. However, rapid warming over the past 100 years has been unusual and, if it continues, the ice shelf could be on par for a complete collapse. Temperatures in the Antarctic Peninsula began rising around 600 years ago, occurring naturally. This was long before manmade...

Proposal follows first continent-wide survey of Antarctic biogeography An international team of scientists have published the first continent-wide assessment of the Antarctic's biogeography, and propose that the landmass should be divided into 15 distinct conservation regions to protect the continent from invasive alien species. The team's findings are published in Diversity and Distributions, while the authors' proposals were outlined today at a lecture to the Antarctic Treaty...

Satellite Observes Rapid Ice Shelf Disintegration In Antarctic
2012-04-06 04:16:49

As ESA´s Envisat satellite marks ten years in orbit, it continues to observe the rapid retreat of one of Antarctica´s ice shelves due to climate warming. One of the satellite´s first observations following its launch on 1 March 2002 was of break-up of a main section of the Larsen B ice shelf in Antarctica — when 3200 sq km of ice disintegrated within a few days due to mechanical instabilities of the ice masses triggered by climate warming. Now, with ten years of...

Invasive Species Put Antarctic Natives At Risk
2012-03-06 11:15:04

As temperatures warm along Antarctica´s outer fringes, it allows for invasive plants and organisms to be carried in inadvertently by visiting scientists and tourists, putting the pristine ecosystem at risk, researchers have found. An international team of researchers, writing in the Proceedings of the National Academy of Sciences (PNAS), said they scoured the clothes and boots of those visiting the southernmost continent and found that most were carrying plant seeds. The risks from...

An international team of researchers has combined data from multiple sources to provide the clearest account yet of how much glacial ice surges into the sea following the collapse of Antarctic ice shelves. The work by researchers at the University of Maryland, Baltimore County (UMBC), the Laboratoire d'Etudes en G©ophysique et Oc©anographie Spatiales, Centre National de la Recherche Scientifique at the University of Toulouse, France, and the University of Colorado's National Snow...

Analysis of direct climate record shows Antarctic tundra persisted until 12 million years ago A painstaking examination of the first direct and detailed climate record from the continental shelves surrounding Antarctica reveals that the last remnant of Antarctic vegetation existed in a tundra landscape on the continent's northern peninsula about 12 million years ago. The research, which was led by researchers at Rice University and Louisiana State University, appears online this week and will...

Scientists have observed a "super-aggregation" of more than 300 humpback whales gorging on the largest swarm of Antarctic krill seen in more than 20 years in bays along the Western Antarctic Peninsula. The sightings, made in waters still largely ice-free deep into austral autumn, suggest the previously little-studied bays are important late-season foraging grounds for the endangered whales. But they also highlight how rapid climate change is affecting the region. The Duke University-led team...

Young penguins in the Antarctic may be dying for lack of food, as melting sea ice reduces the numbers of small fish they consume as their primary food source, according to a new study published Monday in the Proceedings of the National Academy of Sciences (PNAS). The researchers found that just 10 percent of baby penguins tagged are returning in two to four years to breed, a drop of 40-50 percent since the 1970s. The study indicates that species often considered likely "winners" of climate...

Icebergs apparently head off to South Georgia when they are going to die. The blocks of ice break off Antarctica and get swept towards the Atlantic and then ground on the shallow continental shelf that surrounds the 105-mile long island. They dump billions of tons of freshwater into the local marine environment. U.K. scientists say that the giants have quite dramatic impacts, even altering the food webs for South Georgia's animals. "The scale of some these icebergs is something else,"...

Antarctica may not be the world's largest landmass -- it's the fifth-largest continent -- but resting on top of that land is the world's largest ice sheet. That ice holds more than 60 percent of Earth's fresh water and carries the potential to significantly raise sea level. The continent is losing ice to the sea, and scientists want to know how much. Antarctica's ice generally flows from the middle of the continent toward the edge, dipping toward the sea before lifting back up and floating....

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...
