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....

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...

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...
