Gentoo penguins
2014-06-13 07:30:18

Gerard LeBlond for redOrbit.com - Your Universe Online The penguin population from the last ice age to about 1,000 years ago has been on an up and down trend. However, due to a warming climate and retracting ice, certain penguin populations have steadily declined, according to a recent paper which was published in the journal Scientific Reports. The team of scientists from the Universities of Southampton and Oxford used a genetic technique to estimate penguin populations of the past....

West Antarctica's Thwaites Glacier Is Melting Due To Geothermal Heat
2014-06-10 10:18:21

Gerard LeBlond for redorbit.com - Your Universe Online Researchers from the Institute for Geophysics at The University of Texas at Austin (UTIG) have discovered that Thwaites Glacier is being eroded by the ocean, as well as being melted from geothermal heat. Their findings are published in the current edition of the Proceedings of the National Academy of Sciences (PNAS). Accurate information from beneath the West Antarctic Ice Sheet has previously been inaccessible, but new findings of...

Antarctic Ice Sheet Became Unstable At The End Of The Last Ice Age
2014-05-29 05:20:26

redOrbit Staff & Wire Reports - Your Universe Online The Antarctic Ice Sheet started melting approximately 5,000 years earlier than previously believed following the last ice age, according to new research appearing in this week’s edition of the journal Nature. The study, which comes in the wake of research suggesting that destabilization of some of the West Antarctic Ice Sheet has already begun, also said that the shrinkage of the ice sheet accelerated and caused rapid sea level...

CryoSat Shows Increase In Antarctica’s Ice Losses
2014-05-19 03:52:32

ESA Three years of observations from ESA’s CryoSat satellite show that the Antarctic ice sheet is now losing 159 billion tonnes of ice each year – twice as much as when it was last surveyed. The polar ice sheets are a major contributor to the rise in global sea levels, and these newly measured losses from Antarctica alone are enough to raise global sea levels by 0.45 mm each year. These latest findings by a team of scientists from the UK’s Centre for Polar Observation and...

Thwaites Glacier
2014-05-12 13:27:19

redOrbit Staff & Wire Reports - Your Universe Online A rapidly melting region of the West Antarctic Ice Sheet appears to have reached an irreversible state of decline, meaning that nothing can be done to prevent the glaciers from melting into the sea, researchers from NASA and the University of California, Irvine claim in a new study. The researchers came to that conclusion after analyzing four decades worth of data on glaciers located in the Amundsen Sea sector of West Antarctica....

Southern Ocean Winds Keep Antarctica Cold And Australia Dry
2014-05-12 03:02:49

[ Watch The Video: Southern Ocean Winds Keep Antarctica Cool, Australia Dry ] Australian National University New Australian National University-led research has explained why Antarctica is not warming as much as other continents, and why southern Australia is recording more droughts. Researchers have found rising levels of carbon dioxide in the atmosphere are strengthening the stormy Southern Ocean winds which deliver rain to southern Australia, but pushing them further south...

Gerard LeBlond for redOrbit.com - Your Universe Online Antarctica’s ice shelf lays motionless at the surface, but 250 miles below, the Earth is moving at an incredible rate, according to recent research. The new study explains why the upward movement of the Earth’s crust is happening so rapidly in the northern Antarctic Peninsula and was published in this week’s Earth and Planetary Science Letters. Scientists from Newcastle University in the UK led the research with assistance...

Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...

Ross Seal, Ommatophoca rossii
2013-01-01 15:44:30

The Ross seal (Ommatophoca rossii) is a true seal in the Phocidae family, and can only be found on pack ice in Antarctica. This species was formally described by James Clark Ross in 1841, during his British Antarctic Expedition. It is very uncommon to see in its range and rarely leaves the pack ice, with stray individuals occurring off southeast Australia or sub-Antarctic islands. The Ross seal can reach an average length between 5.5 and 6.9 feet, although some females can reach up to 8.2...

The Weddell seal (Leptonychotes weddellii) is a large true seal in the Lobodontini tribe. It is native to Antarctica, with its range consisting of a large “ring” that surrounds Antarctica. This seal will spend most of its time in the water instead of on land. The Weddell seal appears on the IUCN Red List with a conservation status of “Least Concern”.  It is estimated this seal numbers over 800,000 individuals in the wild. First discovered in 1820s by a British sealing captain...

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...

Cryolophosaurus, meaning "cold crest lizard", is a genus of theropod dinosaur from the Early Jurassic Period (Pliensbachian Age). It is known from the Hanson Formation (previously known as the Upper Falla Formation). It was discovered by paleontologist Dr. William Hammer in 1991. It was the first carnivorous dinosaur to be discovered in Antarctica. It was also the first dinosaur from Antarctica to be officially named. Dr. William Hammer and his team unearthed the dinosaur during the...
