elusive emperor penguins
2014-06-26 03:11:24

PLOS Field surveys and satellites complement each other when studying remote penguin populations, according to research published June 25 in the open access journal PLOS ONE by André Ancel from the CNRS at Strasbourg and colleagues. Penguins residing on Antarctica's ice sheets must face moving, breaking, and shifting ice. Accurate monitoring of population trends is critical to understanding the ongoing rapid changes in Antarctic ecosystems. However, the remoteness and logistical...

Satellite Evidence Shows Emperor Penguins' Willingness To Relocate
2014-06-23 12:37:57

Brett Smith for redOrbit.com - Your Universe Online Emperor penguins have a reputation for faithfully returning to the same nesting locations every year but a new study from researchers at the University of Minnesota has found that the reality may not fit this reputation. The study, which is set to be published in an upcoming issue of Ecography, revealed six cases in just three years involving emperor penguins that did not come back to the same area to breed. The report also cited one...

Better Protection From Humans Needed For Antarctica's Ice-Free Land
2014-06-19 06:55:51

April Flowers for redOrbit.com - Your Universe Online Despite the harsh conditions, the number of visitors arriving in the Antarctic is soaring each year. This worries the world's leading environmental scientists who say that Antarctica's ice-free land needs better protection from human activities. Of the 55 Antarctic areas designated for protection, all of them lie close to human activity sites and seven are at a high risk for biological invasions. According to the study, published in...

Antarctic icebergs
2014-06-17 05:19:27

April Flowers for redOrbit.com - Your Universe Online Summer and winter on the Antarctic shore are drastically different. Winters are dark and frozen, while summers are characterized by bright, clear waters, thick with algae and drifting icebergs. Over the last 20 years of warming, however, the region has experienced massive losses of sea ice in the winter that has allowed icebergs to roam freely for most of the year. A new study from the British Antarctic Survey demonstrates how...

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...

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

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...
