Will Adelie Penguins, attempting to cope with climate change, go extinct because they can't find food in the darkness of the Antarctic winter?  A recent paper published in the scientific journal Ecology presents this finding: Adelie Penguins need both ice and light, even just twilight, to find food in the winter. As climate change causes the winter ice to retract south into the darkness, penguins won't have what they need to survive and could ultimately face extinction as a result. ...

Rutgers' Oscar Schofield and five colleagues from other institutions have published in Science, calling for expanded ocean-observing in the Antarctic, particularly in the Western Antarctic Peninsula, or WAP. This mountainous arm of the continent stretches north toward South America. In their review paper, the co-authors, who have done research in the Antarctic, often together, argue that research in this region is imperative: The WAP's climate, they say, is changing faster than the climate...

Ice shelves are retreating in the southern section of the Antarctic Peninsula due to climate change. This could result in glacier retreat and sea-level rise if warming continues, threatening coastal communities and low-lying islands worldwide. Research by the U.S. Geological Survey is the first to document that every ice front in the southern part of the Antarctic Peninsula has been retreating overall from 1947 to 2009, with the most dramatic changes occurring since 1990. The USGS previously...

A major scientific report released on Tuesday showed that rapid ice loss in West Antarctica will likely contribute heavily to a projected sea level rise of up to 4.5 feet by 2100, AFP reported. For years scientists believed that most of Antarctica's continent-sized ice sheet was highly resistant to global warming, and that the more vulnerable West Antarctic ice block would remain intact for thousands of years to come. But according to the review by more than 100 experts on the Scientific...

'Antarctic Climate Change and the Environment' The first comprehensive review of the state of Antarctica's climate and its relationship to the global climate system is published this week (Tuesday 1 December) by the Scientific Committee on Antarctic Research (SCAR). The review - Antarctic Climate Change and the Environment "“ presents the latest research from the icy continent, identifies areas for future scientific research, and addresses the urgent questions that policy makers have...

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,...

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...

The Wilkins Ice Shelf is at risk of partly breaking away from the Antarctic Peninsula as the ice bridge that connects it to Charcot and Latady Islands looks set to collapse. The beginning of what appears to be the demise of the ice bridge began this week when new rifts forming along its centre axis resulted in a large block of ice breaking away. The Advanced Synthetic Aperture Radar (ASAR) images acquired on 2 April by ESA's Envisat satellite confirm that the rifts are quickly expanding...

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...
