Subglacial Life Found In Ice Cores From Lake Vostok, Antarctica
2013-07-05 11:58:56

Lawrence LeBlond for redOrbit.com - Your Universe Online Lake Vostok, the largest of some 400 subglacial lakes scattering Antarctica's frozen depths, has been the subject of ambitious research for at least the past 15 years. Lying more than 2 miles below the surface, the lake was first drilled in 1998 by a team of Russian, French and American scientists. Because the lake is buried so deeply under an Antarctic glacier and is so dark and cold, researchers have surmised it would be an...

Antarctic King Crabs May Actually Be Native
2013-07-05 05:58:25

Brett Smith for redOrbit.com - Your Universe Online Citing the recent discovery of a major colony of King crabs near Antarctica, some global warming alarmists theorize that rising temperatures have allowed the crabs to claim territory that was previously uninhabitable. According to a new review of crab records published in the journal PLOS ONE, the crabs are not newly established settlers; they've been there all along. The so-called "invasion hypothesis is based on a geographically...

Ghost Lake Found Beneath Antarctica's Ice Sheet
2013-07-03 05:32:53

April Flowers for redOrbit.com - Your Universe Online A vast crater has been found in Antarctica's icy surface by the European Space Agency's (ESA) CryoSat satellite. The crater was formed, scientists believe, when a lake lying under about 2 miles of ice drained suddenly. There are lakes of fresh water trapped without a connection to the ocean, deep below the thick ice sheet that covers Antarctica. Scientists who are trying to understand water transport and ice dynamics beneath the...

Carbon Dioxide Absorption In Antarctic Seas Studied
2013-06-13 09:39:28

Georgia Institute of Technology The seas around Antarctica can, at times, resemble a garden. Large-scale experiments where scientists spray iron into the waters, literally fertilizing phytoplankton, have created huge man-made algal blooms. Such geoengineering experiments produce diatoms, which pull carbon dioxide out of the air. Experts argue that this practice can help offset Earth´s rising carbon dioxide levels. However, the experiments are controversial and, according to a new...

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,...

Mount Erebus
2014-08-19 09:49:48

Mount Erebus is an active volcano that can be found on Ross Island in Antarctica. It is the second largest volcano in Antarctica, reaching a height of 12,448 feet. Sir James Clark Ross discovered it in 1841 in mid-eruption and named it and another volcano Mount Erebus and Mount Terror, after two of his ships. The first people to climb the volcano and reach its summit were part of Sir Ernest Shackleton's party, including Professor Edgeworth David, Jameson Adams, and Dr. Eric Marshall. Mount...

Antarctica
2013-02-18 10:15:24

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...

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...
