Causes Of 2011 Arctic Ozone Hole Pinpointed By NASA
2013-03-12 10:16:04

NASA A combination of extreme cold temperatures, man-made chemicals and a stagnant atmosphere were behind what became known as the Arctic ozone hole of 2011, a new NASA study finds. Even when both poles of the planet undergo ozone losses during the winter, the Arctic´s ozone depletion tends to be milder and shorter-lived than the Antarctic´s. This is because the three key ingredients needed for ozone-destroying chemical reactions –chlorine from man-made...

Autonomous Machine Makes Over-ice Travel Safer
2013-03-04 11:09:54

National Science Foundation A century after Western explorers first crossed the dangerous landscapes of the Arctic and Antarctic, researchers funded by the National Science Foundation (NSF) have successfully deployed a self-guided robot that uses ground-penetrating radar to map deadly crevasses hidden in ice-covered terrains. Deployment of the robot--dubbed Yeti--could make Arctic and Antarctic explorations safer by revealing unseen fissures buried beneath ice and snow that could...

NASA Sub Helps Explore Depths Of Antarctica
2013-03-01 21:01:43

Lee Rannals for redOrbit.com — Your Universe Online NASA is best known for its explorations away from this planet, but the US space agency has a whole other program aimed at investigating the depths of this planet. One NASA researcher from the Jet Propulsion Laboratory in Pasadena, California joined up with an international Antarctic expedition last month to try and explore an unexplored aquatic environment on Earth. Alberto Behar used a small robotic sub about the size of a...

Fluffy Antarctic Snow Provides New Insights On Climate Cycles
2013-02-26 10:35:56

April Flowers for redOrbit.com - Your Universe Online A team of scientists, led by researchers at the University of California, San Diego, has found particles from the upper atmosphere trapped in a deep pile of Antarctic snow that hold clear chemical traces of global meteorological events. The study was published in the early online edition of the Proceedings of the National Academy of Sciences and suggests anomalies in oxygen found in sulfate particles coincide with several episodes of...

Huge Data Combined Into A Unique Georeferenced Macrobenthic Collection Database
2013-02-19 10:46:31

Pensoft Publishers A new peer-reviewed data paper offers a comprehensive, open-access collection of georeferenced biological information about the Antarctic macrobenthic communities. The term macrobenthic refers to the visible-for-the-eye organisms that live near or on the sea bottom such as echinoderms, sponges, ascidians, crustaceans. The paper will help in coordinating biodiversity research and conservation activities on species living near the ocean bottom of the Antarctic. The data...

Ocean Circulation Disrupted By A Thinning Antarctic Ozone Layer
2013-02-01 09:27:29

redOrbit Staff & Wire Reports - Your Universe Online The impact of the depleting Antarctic ozone layer on both the shifting direction of the Southern Hemisphere´s jet stream and the way in which the waters of the nearby southern oceans mix together is the topic of research published in this week´s edition of the journal Science. In one study, a team of researchers led by earth scientist Darryn W. Waugh of Johns Hopkins University wrote that the hole in the region´s...

Search Team Confirms Three Canadians Killed After Plane Goes Down In Antarctic Mountains
2013-01-29 06:42:54

Lawrence LeBlond for redOrbit.com - Your Universe Online Three Canadians who were reported missing last Wednesday after an emergency beacon on their plane started transmitting over Queen Alexandra Mountains in Antarctica, have been confirmed dead by the National Science Foundation (NSF) on Monday. Officials with the US Antarctic Program (USAP) and Antarctica New Zealand called off their search-and-rescue efforts on Monday, saying the crash wreckage was in a perilous position on a steep...

Three Canadians Believed To Have Crashed In Antarctic Mountains, Rescue Delayed Due To Bad Weather
2013-01-24 08:21:55

Lawrence LeBlond for redOrbit.com - Your Universe Online Three Canadians who were aboard a small plane flying over the Antarctic are presumably missing after an emergency locator started transmitting a signal Wednesday night. Matters were complicated when bad weather forced a search and rescue mission to go on hold. The flight was going from the US-operated McMurdo Station near the South Pole to Zucchelli Station, an Italian research base in Terra Nova Bay. The emergency locator began...

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...

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...
