NASA's Operation IceBridge Mission Contributes To New Map Of Antarctica
2013-06-06 09:26:57

NASA A new dataset called Bedmap2 gives a clearer picture of Antarctica from the ice surface down to the bedrock below. Bedmap2 is a significant improvement on the previous collection of Antarctic data–known as Bedmap–that was produced more than 10 years ago. The product was a result of work led by the British Antarctic Survey, where researchers compiled decades worth of geophysical measurements, such as surface elevation measurements from NASA's Ice, Cloud and Land Elevation...

Researchers Map New Jersey Sea-Level Changes Over Last 10,000 Years
2013-05-29 09:07:40

April Flowers for redOrbit.com - Your Universe Online The public and policymakers alike were caught off guard when Hurricane Sandy hit the east coast of the US last fall. The majority of the destruction came from the storm surge and flooding that followed the storm, leading researchers to pay attention to how climate change and sea-level rise may have played a role in the disaster, and how those same factors may impact the shoreline in the future. Benjamin P. Horton, an associate...

Earth’s Ice Sheets More Stable Than Once Thought
2013-05-17 10:44:21

April Flowers for redOrbit.com - Your Universe Online For decades, researchers have used ancient shorelines to predict the stability of today´s largest ice sheets in Greenland and Antarctica. High shoreline markings from three million years ago as Earth was going through a warm period were thought to be evidence of a high sea level due to ice sheet collapse at the time — an assumption that has led many scientists to believe that if the world´s largest ice sheets collapsed...

Melting Glaciers Contributing Significantly To Sea Rise
2013-05-17 09:49:29

April Flowers for redOrbit.com - Your Universe Online Scientists have known for some time that melting glaciers are contributing to the global sea-level rise. However, the amount being contributed by each region of the planet has never before been calculated with the accuracy of a new study led by researchers at the University of Colorado at Boulder and Clark University. Ninety-nine percent of Earth´s land ice is locked up in the Greenland and Antarctica ice sheets. The study,...

WASHINGTON, May 16, 2013 /PRNewswire-USNewswire/ -- A new study of glaciers worldwide using observations from two NASA satellites has helped resolve differences in estimates of how fast glaciers are disappearing and contributing to sea level rise. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The new research found glaciers outside of the Greenland and Antarctic ice sheets, repositories of 1 percent of all land ice, lost an average of 571 trillion pounds (259 trillion...

Antarctic Ecosystem Caused Rapid Evolution 041913
2013-04-19 09:39:52

redOrbit Staff & Wire Reports - Your Universe Online The development of the sea-ice ecosystem in the circum-Antarctic Southern Ocean may have triggered further adaptation and evolution of larger organisms such as baleen whales and penguins, according to a new study published Thursday in the journal Science. The area´s ecosystem can be traced back to the emergence of the Antarctic ice sheets some 33.6 million years ago and plays an important role in global marine food webs and...

For Antarctic Clams Age Matters
2013-04-19 09:03:56

April Flowers for redOrbit.com - Your Universe Online According to a new study from the British Antarctic Survey (BAS), the University of Kiel, and the Alfred Wegener Institute, age matters for Antarctic clams when it comes to adapting to the effects of climate change. The study, published in the journal Global Change Biology, provides new insights into the likely impact that predicted environmental change could have on the future of ocean biodiversity. The Antarctic clam (laturnula...

1000-year Antarctic Peninsula climate reconstruction A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid 20th Century. Summer ice melt affects the stability of Antarctic ice shelves and glaciers. The research, published this week in the journal Nature Geoscience, adds new knowledge to the international effort that is required to understand the causes of environmental change in Antarctica and...

Antarctic Glacial Melt May Be Natural
2013-04-15 11:05:27

Brett Smith for redOrbit.com - Your Universe Online As the debate over climate change continues, so does the publication of studies that support or challenge the notion that human activity is the main driver of rising temperatures. According to a new study in“¯Nature Geoscience, the dramatic thinning of glaciers in Western Antarctica is due to natural variation, and cannot be attributed directly to carbon emissions. "If we could look back at this region of Antarctica in...

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...

Weddell Seal, Leptonychotes weddellii
2012-06-27 21:35:24

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...

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...

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...
