Antarctic ice shelf
2014-03-03 05:04:27

McGill University In the mid-1970s, the first available satellite images of Antarctica during the polar winter revealed a huge ice-free region within the ice pack of the Weddell Sea. This ice-free region, or polynya, stayed open for three full winters before it closed. Subsequent research showed that the opening was maintained as relatively warm waters churned upward from kilometers below the ocean's surface and released heat from the ocean's deepest reaches. But the polynya -- which...

Adelies Ross Sea ice floes
2014-02-27 05:21:14

April Flowers for redOrbit.com - Your Universe Online The Ross Sea is a major, biologically productive ecosystem in the Antarctic, which "clearly will be extensively modified by future climate change" in the coming decades as longer periods of ice-free open water are created by rising temperatures and changing wind patterns. According to a new paper funded by the National Science Foundation (NSF), these ice-free periods affect the life cycles of both predators and prey. The research...

pine island glacier
2014-02-21 04:41:24

redOrbit Staff & Wire Reports - Your Universe Online Previous instances of rapid thinning of Pine Island Glacier suggests that current ice loss in the Antarctic could continue for several more decades, a team of geologists from the US, UK and Germany report in this week’s edition of the journal Science. Pine Island Glacier, which is part of the West Antarctic Ice Sheet, is rapidly accelerating, thinning and retreating, and the researchers report that it has thinned rapidly in the...

Disappearing Snow Increases Risk Of Ice Shelves Collapsing  In Antarctica
2014-01-30 08:19:42

British Antarctic Survey Sea-level research in Antarctica A number of floating ice shelves in Antarctica are at risk of disappearing entirely in the next 200 years, as global warming reduces their snow cover. Their collapse would enhance the discharge of ice into the oceans and increase the rate at which sea-level rises. A rapid reduction of greenhouse gas emissions could save a number of these ice shelves, researchers at Utrecht University and the British Antarctic Survey say in a new...

Climate Change In Antarctica Partially Driven By Warming In The North And Tropical Atlantic Ocean
2014-01-23 04:26:22

April Flowers for redOrbit.com - Your Universe Online A team of New York University climatologists has concluded that the gradual warming of the North and Tropical Atlantic Ocean is adding to climate change in Antarctica. The conclusions rely on more than three decades of atmospheric data and reveal new ways in which Antarctic climate change is affected by distant regional conditions. "Our findings reveal a previously unknown—and surprising—force behind climate change that is...

Sea Anemones In Antarctica Find A Home On The Ice
2014-01-17 07:46:08

April Flowers for redOrbit.com - Your Universe Online A team of scientists and engineers with the Antarctic Geological Drilling (ANDRILL) Program used a camera-equipped robot to explore beneath the Ross Ice Shelf off Antarctica, making an astonishing discovery. The team found many thousands of small sea anemones that were burrowed into the underside of the ice shelf with their tentacles protruding into frigid water like flowers on a ceiling. "The pictures blew my mind," said...

Joint Antarctic School Expedition Sends High-school Students To Chilean Station
2014-01-15 06:40:23

National Science Foundation Three high-school students and a teacher from Wisconsin will participate in a joint pilot program of the US and Chilean Antarctic programs that will send them to a Chilean research station this February for hands-on experience with Antarctic environments and ecosystems research. The US students and teacher, from the Monona Grove, Wisc., school district, will join their Chilean peers--winners of Chile's Antarctic School Fair--in the first Joint Antarctic...

Pine Island Glacier Retreating
2014-01-14 14:44:51

Lee Rannals for redOrbit.com - Your Universe Online Antarctica’s Pine Island Glacier (PIG) is now in an irreversible retreat, according to a study published in the journal Nature Climate Change. PIG is one of the biggest single contributors to global sea-level rise, and the latest study says that it could add as much as 0.39-inches to ocean levels in 20 years. “Over the past 40 years Pine Island Glacier in West Antarctica has thinned at an accelerating rate, so that at present it is...

Antarctica Holds Subglacial Valley Bigger Than The Grand Canyon
2014-01-14 09:44:05

[ Watch the Video: A Giant Is Lurking Beneath Antarctica's Ice ] Gerard LeBlond for redOrbit.com - Your Universe Online A team of scientists from Newcastle University, the University of Bristol’s Glaciology Centre, the British Antarctic Survey and the universities of Edinburgh, Exeter and York, have discovered a giant trench below the ice in Antarctica. The research team has spent the last three seasons in the West Antarctic region investigating and mapping the area. Recently, they...

Shrinking Habitat Doesn't Keep Emperor Penguins From Breeding
2014-01-09 11:35:03

[ Watch the Video: Emperor Penguins Are Breeding On Ice Shelves ] Gerard LeBlond for redorbit.com - Your Universe Online The emperor penguins of Antarctica, which have lost much of their breeding habitat due to shrinking ice pack, have shown their resiliency to environmental impacts by moving to new breeding locations where ice is thicker, as has been seen via satellite images, reports BBC News' Jonathan Amos. A new study, published in the online journal PLOS ONE, describes the...

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...

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...
