Young penguins in the Antarctic may be dying for lack of food, as melting sea ice reduces the numbers of small fish they consume as their primary food source, according to a new study published Monday in the Proceedings of the National Academy of Sciences (PNAS). The researchers found that just 10 percent of baby penguins tagged are returning in two to four years to breed, a drop of 40-50 percent since the 1970s. The study indicates that species often considered likely "winners" of climate...

The Antarctic Peninsula has warmed rapidly for the last half-century or more, and recent studies have shown that an adjacent area, continental West Antarctica, has steadily warmed for at least 30 years, but scientists haven't been sure why. New University of Washington research shows that rising sea surface temperatures in the area of the Pacific Ocean along the equator and near the International Date Line drive atmospheric circulation that has caused some of the largest shifts in Antarctic...

A team of scientists in the United Kingdom and the United States has warned that the native fauna and unique ecology of the Southern Ocean, the vast body of water that surrounds the Antarctic continent, is under threat from human activity. Their study is published this week in the peer-reviewed journal Annals of the New York Academy of Sciences. "Although  Antarctica is still the most pristine environment on Earth, its marine ecosystems are being degraded through the introduction of...

In the latest issue of 'Current Biology', researchers from the British Antarctic Survey (BAS) have published an analysis of growth rates of a tiny sea animal. Samples of the bryozoan, (Cellarinella nutti) a sea-bed filter-feeding animal that looks like branching twigs, collected during Captain Scott's Antarctic trips, are yielding data that may prove valuable in projecting climate change, BBC News is reporting. The samples were collected in the Ross Sea, where Capt. Robert Falcon Scott...

WATERBURY, Vt., Feb. 14, 2011 /PRNewswire/ -- Atlanta Photographer Santiago Vanegas sailed below the Antarctic Circle in 2009 aboard a Quark Expeditions vessel. From the 11,000 pictures he took during the 15-day voyage, he has chosen 50 to include in an exhibit titled - Antarctica: Photographs by Santiago Vanegas. The venue for the year long exhibit is the Transportation Hall of Atlanta Hartsfield Jackson International Airport, the busiest in the world. (Photo:...

Russian scientists are set to pierce through Antarctica's frozen surface to reveal the secrets of an icebound lake that has been sealed deep there for the past 15 million years. Alexei Turkeyev, head of the Russian polar Vostok Station, told Reuters by satellite phone that scientists have "only a bit left to go." His team has been drilling for weeks in a race to reach the lake -- buried 12,000 feet beneath the polar ice cap -- before the end of the brief Antarctic summer. With the...

Scientists studying the world's most enigmatic lake have only 165 feet left to drill as time is running out. Vostok is a sub-glacial lake in Antarctica, hidden about 13,000 ft beneath the ice sheet. With the Antarctic summer almost over, temperatures will soon start to drop. Scientists will leave the remote base on February 6, when conditions are still mild enough for a plane to land. The team has not stopped drilling for weeks. "It's like working on an alien planet where no one has been...

Scientists have previously shown that West Antarctica is losing ice, but how that ice is lost remained unclear. Now, using data from Earth observing satellites and airborne science missions, scientists are closing in on ice loss culprits above and below the ice. The findings, presented Dec. 15 at the fall meeting of the American Geophysical Union (AGU) in San Francisco, Calif., are expected to improve predictions of sea level rise. Time Not Healing Glacial Wounds A new analysis by Ted...

Amundsen Sea Polynya International Research Expedition (ASPIRE) Combines Research and Education In a unique and complex example of "science diplomacy," teams of U.S. and Swedish scientists are sailing this month aboard two research vessels to study the ecology of the Amundsen Sea, one of the least-explored and most productive bodies in Antarctic waters, and to gauge the potential effects of a changing climate on the Southern Ocean. The joint American and Swedish expedition, involving the U.S....

The National Science Foundation has signed a five-year, $34.5-million agreement with the University of Wisconsin-Madison to operate a unique telescope--a cubic kilometer in volume--buried in the Antarctic ice sheet between 1,400 meters and 2,400 meters deep. The collaborative agreement covers the cost of operating the IceCube Neutrino Observatory, located in the ice under the U.S. Amundsen-Scott South Pole Station. The observatory records the rare collisions of neutrinos, elusive sub-atomic...

Antarctic Minke Whale, Balaenoptera bonaerensis
2013-06-22 16:21:07

The Antarctic minke whale (Balaenoptera bonaerensis), also known as the southern minke whale, is one of two minke whales within the Mysticeti suborder, which contains baleen and rorqual whales. It can be found in every ocean in the southern hemisphere, residing in Antarctic waters in the summer months and northern waters in the winter months, where its range overlaps that the smaller common minke whale. The Antarctic minke whale was once classified with the common minke whale as a single...

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...

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...

Crabeater Seal, Lobodon carcinophagus
2012-06-26 14:40:11

The crabeater seal (Lobodon carcinophagus) is a true seal that can be found around the whole of Antarctica. Its range also includes small areas in South America, New Zealand, Africa, and Australia. It resides on the pack ice zone for the entire year, even as it shifts seasonally, and prefers to stay in the continental shelf area in water with a depth of less than 1,968 feet. Because the populations are so wide spread and are sufficiently mixed, there have been no subspecies found. Because...
