Antarctic FAQ
No one lives in Antarctica on a permanent basis. The Antarctic Treaty guarantees that Antarctica is to be used for "peaceful purposes and for scientific research". This means that no one can have Antarctica as their permanent mailing address. Only scientists are allowed to spend any time there. There are over 5,000 scientists and support staff from 27 different countries in Antarctica during the Antarctic summer season.

About Antarctica: Seals
Although there are 35 species of seals, only six types live in Antarctica: Antarctic Fur Seals, Crabeater Seals, Leopard Seals, Ross Seals, and Weddell Seals. However, these six species make up the majority of the world's seal population. With no natural land predators, such as polar bears or man, Antarctic seals behave much differently than northern seals--showing little fear of man.

Admiral Byrd and Antarctica
Born into an aristocratic Virginia family in 1888, Richard E. Byrd served in and worked with the Navy for nearly 45 yeras to become one of the most active explorers of the Antarctic. Byrd began his career after graduating from the U.S. Naval Academy in 1912, when he learned to fly and explored the world. Byrd went on to gain international fame and recognition for his dedication to researching and preserving the unique environment in Antarctica.

Antarctic Ice Loss
However, Antarctica’s contribution to future sea level rise is far from certain. It is much too early to tell whether the variations found by Rignot capture the real behavior of the Antarctic ice sheets, whether they are natural, or whether they indicate a substantial (or even sustainable) increase in ice-melt. These uncertainties are highlighted in a just-published paper by Antarctic researchers Hugb Corr and David Vaughn (2008).

Antarctica is the best place in the world to find meteorites, and the search for Antarctic meteorites begins with the search for blue ice. ... A fallen meteorite in Antarctica is quickly covered by snow and buried in one of the great Antarctic glaciers. The glaciers slowly move toward the ocean, and their ice turns blue because all its air bubbles are squeezed out.

Though most of the East Antarctic sheet sits on land that is above sea level, the portion on the margin of Wilkes Land lies more than 1,000 meters below sea level, which means it is partly supported by the ocean. If sea level rises a little, this causes the ice sheet to lift off of its bed, allowing it to flow faster to the sea. ... Shells of microorganisms that fell to the seafloor long ago also provide clues. In addition to their climate work, the researchers use the sediments to view Antarctica's tectonic history.

The Antarctic Treaty | SCINI-Penguin
The Antarctic Treaty. Posted on October 19, 2013 by StacyKim. Howdy, this is Polar Bear B. I’m here to explain a little bit about why we study in Antarctica. One of the reasons is that Antarctica is the only place on earth that has been set aside by for pure scientific research. Antarctica is the only significant piece of land on Earth not governed by a country or person. This is rather astonishing, considering that Antarctica is whole continent and comprises 8.9% of the world’s land area, larger than either Australia or Europe.

Many people think of Antarctica as a windy place. That is true, but only near the edges of the continent.

There the winds almost always blow from the same direction - the compass quadrant containing Dome A, the highest point on the Antarctic Plateau. At Dome A, typical wind speeds are less than a few km per hour, making it possibly the calmest place on Earth.

Antarctic Governance: From ATCM to A Permanent Antarctic
The Antarctic Treaty System (ATS) with its core being the 1959 Antarctic Treaty has played an important role in the international governance of Antarctica and safeguarding the Antarctic peace and order.

The Antarctic regime has undergone the process from a “decentralized approach” to the partial institutionalization and even to the overall institutionalization during the past 53 years.
Why is The Antarctic Treaty Important?
The Antarctic Treaty is an unusual occurrence in the realm of international relations. It is a treaty that does not recognize any sovereign nation’s claim on any part of the Antarctic territory as well as a treaty that states that the purpose of the Antarctic continent is dedicated to “peace and science.” ( Initially The Antarctic Treaty was also used to demilitarize the continent.

Will Antarctic ice loss continue at this rate? This is not obvious - Antarctica is a very high continent centered on the south pole and therefore surrounded by a powerful polar atmospheric cell which communicates little with the warmer air to the north (this is not true of Greenland, which is farther from the pole and has a different climate and communication outside the north atmospheric Polar Cell).

Warming in Antarctica Tied to Changes in the Atlantic
Scientists have long known that the Antarctic Peninsula in West Antarctica is subject to climate change. ... So, for this paper, researchers focused on the Atlantic, which had been overlooked as a force behind Antarctic climate change. It is remarkable that the recent 30-year trend in North Atlantic Ocean warming is driving climate change in West Antarctica, Holland said.

The rst is the most obvious: a key requirement for Australian Antarctic work was a penis, and until 1975, when three women were allowed on the continent for several weeks in an ofcial capacity, Australia simply did not allow women to work in its polar claim at all. ... To see how this tension has played out in the AAT, this article turns to two brief examples: the debates over Australia’s Antarctic station rebuild-ing program in the 1980s and media coverage of the AAT’s rst private settlers, who lived in Antarctica in 1995.

Antarctic Clouds and Climate: A Study with Two Generations of NASA Earth Science Enterprise Data. Co-PI with Dan Lubin, UCSD/Scripps. The University of Idaho’s contribution to the proposed work consists mainly of analyzing high-resolution infrared spectra from the Infrared Interferometer Spectrometer (IRIS), the Interferometric Monitor for Greenhouse Gases (IMG), and the Atmospheric Infrared Sounder (AIRS), obtained over Antarctica, to produce several data products.

Flight. BOOMERANG was launched on December 29, 1998. For the next 10.5 days it floated slowly around the Antarctica at an altitude of 120,000 feet. We kept track of its status via a satellite link, and refined our observations as we analyzed the data that came through the link. Finally, after a complete circle, the payload was dropped by parachute to a spot about 50 km from the launch pad, for an easy recovery.

Biology in Antarctica 2012-13
Antarctic waters are reported to have a high percentage of endemic organisms. Many of these purported endemic species have been described as circumpolar (i.e., living in connected populations all the way around Antarctica). Although there has been considerable work on the general biology of Antarctic marine fauna and estimates of Antarctic biodiversity, there have been few studies focused on understanding genetic patterns.

Exploring Global Climate Impact If Antarctica’s Ice Sheets Melt
– As the world anticipates a global climate change meeting next month in Paris, there is compelling historical evidence that the West Antarctic Ice Sheet is vulnerable to rapid retreat and collapse, says climate scientist Alan Condron at the University of Massachusetts Amherst, yet very few if any studies have explored what might happen to Earth’s climate if Antarctica’s ice sheets were.

Since its discovery in the early 1820s, Antarctica has drawn interest from a myriad of adventurers, scientists, fishermen and policymakers across the world. In 1958, the People’s Republic of China (PRC) tried to join a group of nations that had composed the Antarctic Treaty but was thwarted by the many non-Soviet countries suspicious of its intentions. In the late 1970s, the PRC again renewed its interest in Antarctica and, in 1985, became a full Consultative Party (CP) to the Antarctic Treaty.

West Antarctica’s ice sheet is an issue of active research and societal concern. Its instability has the potential to cause significant economic impact resulting from an increase in global sea level. West Antarctica is the largest remaining ice-filled marine basin on Earth. Antarctica’s ice sheet is drained by fast-moving ice streams that extend far into the ice-sheet interior. The West Antarctic ice sheet has lost nearly two thirds of its mass, since the peak of the last ice age nearly 20,000 years ago.
