Antarctic Ozone Hole Is Shrinking
2012-09-15 08:17:08

April Flowers for redOrbit.com - Your Universe Online The United Nations reported Friday that the hole in the ozone layer is expected to be smaller this year over the Antarctic than last year. They claim this illustrates how a ban on harmful substances has slowed ozone depletion. The ozone layer in the Earth's atmosphere contains relatively high concentrations of ozone (03).  This layer is found mainly in the lower portion of the stratosphere and absorbs 97 — 99% of the Sun's...

Methane Reservoir Beneath Antarctic Ice Sheet
2012-08-30 08:32:12

April Flowers for redOrbit.com - Your Universe Online A recent study of the Antarctic Ice Sheet suggests that it could be a largely overlooked source of the potent greenhouse gas methane. An international team of scientists from the University of Bristol, the University of California, Santa Cruz, the University of Alberta, Edmonton, and the University of Utrecht, demonstrate that old organic matter in sedimentary basins located beneath the Antarctic Ice Sheet may have been converted to...

Antarctic Ice Shelf Collapse Has Been Occurring For 600 Years, Manmade Climate Change Is Now Adding To Problem
2012-08-23 10:53:35

Lawrence LeBlond for redOrbit.com - Your Universe Online The Antarctic Peninsula has been continually shrinking for centuries, since long before the Industrial Revolution, according to an international team of researchers. However, rapid warming over the past 100 years has been unusual and, if it continues, the ice shelf could be on par for a complete collapse. Temperatures in the Antarctic Peninsula began rising around 600 years ago, occurring naturally. This was long before manmade...

Medical Evacuation In Antarctic
2012-08-09 09:23:01

Patient is currently stable but may require corrective surgery National Science Foundation (NSF) officials have set in motion the necessary steps to airlift a patient from McMurdo Station, one of three year-round stations NSF maintains in Antarctica. The patient's condition may require treatment beyond what can be provided at the station's medical facility. The patient, whose identity NSF is not releasing, is currently stable but may require immediate corrective surgery best delivered...

Antarctic Was Tropical During The Eocene Epoch

Brett Smith for redOrbit.com - Your Universe Online As the world´s greatest athletes compete for gold, silver, and bronze in London, new scientific evidence suggests that future summer Olympics could be hosted in a more remote location: Antarctica. An international team of climate scientists has discovered 50 million-year-old fossilized pollen in the seabed off the eastern coast of the polar continent, according to their report published this week in the journal Nature. The...

Tropical Climate In The Antarctic
2012-08-01 14:14:47

Palm trees once thrived on today's icy coasts 52 million years ago Given the predicted rise in global temperatures in the coming decades, climate scientists are particularly interested in warm periods that occurred in the geological past. Knowledge of past episodes of global warmth can be used to better understand the relationship between climate change, variations in atmospheric carbon dioxide and the reaction of Earth's biosphere. An international team led by scientists from the Goethe...

Ancient Antarctica Was A Completely Different Place
2012-06-18 04:13:26

A new university-led study with NASA participation finds ancient Antarctica was much warmer and wetter than previously suspected. The climate was suitable to support substantial vegetation -- including stunted trees -- along the edges of the frozen continent. The team of scientists involved in the study, published online June 17 in Nature Geoscience, was led by Sarah J. Feakins of the University of Southern California in Los Angeles, and included researchers from NASA's Jet Propulsion...

Proposal follows first continent-wide survey of Antarctic biogeography An international team of scientists have published the first continent-wide assessment of the Antarctic's biogeography, and propose that the landmass should be divided into 15 distinct conservation regions to protect the continent from invasive alien species. The team's findings are published in Diversity and Distributions, while the authors' proposals were outlined today at a lecture to the Antarctic Treaty...

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...
