Image 1 - Antarctic Expedition Checks CryoSat Data
2011-12-10 04:41:07

Next week marks 100 years since Roald Amundsen reached the South Pole. As a team of scientists brave the Antarctic to validate data from ESA´s CryoSat mission, it´s hard to imagine what these first intrepid explorers would have thought of today´s advances in polar science. The remote and vast expanse of the Antarctic is arguably the most hostile environment on Earth — infamously claiming the lives of Captain Robert Scott and his party all those years ago in their fated...

Accelerated melting of two fast-moving outlet glaciers that drain Antarctic ice into the Amundsen Sea Embayment is likely the result, in part, of an increase in sea-surface temperatures in the tropical Pacific Ocean, according to new University of Washington research. Higher-than-normal sea-level pressure north of the Amundsen Sea sets up westerly winds that push surface water away from the glaciers and allow warmer deep water to rise to the surface under the edges of the glaciers, said...

Scientists have created a detailed map called BEDMAP of Antarctica's rock bed that lies underneath its icy surface. The map gives a view of the landscape beneath the ice, and incorporates decades of survey data acquired by planes, satellites, ships and even people on dogsleds. In the map, the highest elevations are marked in red/black, while the light blue color shows the extent of the continental shelf.  The lowest elevations are dark blue, some of which lie below today's seal...

In order to identify the flight routes of the birds, postgraduate Matthias Kopp, under the guidance of Dr. Peter, equipped South Polar skuas with geolocators in their breeding areas on King George Island, about 120 kilometers off the Antarctic Mainland. Thus he has been screening their position data over a period of several years, followed by an analysis together with British colleagues and a scientist from Switzerland. "With the help of these data we can now for the first time...

A remarkable ESA campaign in one of the remotest regions on Earth has been fundamental in ensuring that the SMOS mission is delivering reliable data to improve our understanding of Earth´s water cycle. The two-year campaign set out to answer a simple but important question: do the microwave signals of a particular wavelength emitted from the surface the Antarctic ice shelf towards the SMOS satellite change over time? For a satellite mission that maps variations in soil...

The end of the last ice age and the processes that led to the melting of the northern and southern ice sheets supply basic information on changes in our climate. Although the maximum size of the ice sheet in the northern hemisphere during the last ice age is relatively well known, there is little reliable data on the dimensions of the Antarctic ice sheet. A publication appearing in the journal “Science” on 1 December now furnishes indications that the two hemispheres attained...

Radiocarbon bomb pulse revelations One hundred years ago, two teams of explorers raced to be the first to reach the South Pole. Roald Engelbregt Gravning Amundsen reached the South Pole on December 14, 1911. Thirty-three days later on 17 January 1912 the Terra Nova Expedition led by Robert Falcon Scott arrived at the Pole in second place. At the same time in East Antarctica, the Australasian Antarctic Expedition led by Douglas Mawson was searching for the South Magnetic Pole. On...

Application deadline is Nov. 28, 2011; deployments to take place Jan. 13-20, 2012 The National Science Foundation (NSF), manager of the U.S. Antarctic Program is accepting written requests from professional journalists to report on scientific research supported by NSF's Office of Polar Programs (OPP). Selected journalists will deploy to Antarctica for approximately one working week. NSF annually selects a small group of journalists, representing a range of news organizations, to make...

Image 1 - Researchers Unravel Gamburtsev Mountains Enigma
2011-11-17 10:35:05

Researchers funded by the National Science Foundation may have finally found how Antarctica´s Gamburtsev Subglacial Mountains were formed, a conundrum that has plagued scientists since they were first discovered in 1958. The international team of scientists explored the subglacial mountain range -- buried under nearly 10,000 feet of ice -- during the International Polar Year (2007-2009) by using two twin-engine aircraft equipped with ice penetrating radar, gravity meters and...

Researchers To Drill Beneath Massive Antarctic Ice Shelf
2011-11-10 04:49:24

[ Watch the Video ] An international team of researchers funded by NASA and the National Science Foundation (NSF) will travel next month to one of Antarctica's most active, remote and harsh spots to determine how changes in the waters circulating under an active ice sheet are causing a glacier to accelerate and drain into the sea. The science expedition will be the most extensive ever deployed to Pine Island Glacier. It is the area of the ice-covered continent that concerns scientists...

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...

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...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
