EDMONTON, June 20, 2014 /CNW/ - Drawing attention to improvements made by the operator, the Transportation Safety Board of Canada (TSB) today released its investigation report into the January 2013 collision with terrain of an aircraft operated by Kenn Borek Air Ltd. On 23 January 2013, the de Havilland DHC-6-300 Twin Otter departed South Pole Station, Antarctica, for a visual flight rules (VFR) repositioning flight to Terra Nova Bay, with a crew of 3 on board. When an...

Better Protection From Humans Needed For Antarctica's Ice-Free Land
2014-06-19 06:55:51

April Flowers for redOrbit.com - Your Universe Online Despite the harsh conditions, the number of visitors arriving in the Antarctic is soaring each year. This worries the world's leading environmental scientists who say that Antarctica's ice-free land needs better protection from human activities. Of the 55 Antarctic areas designated for protection, all of them lie close to human activity sites and seven are at a high risk for biological invasions. According to the study, published in...

Antarctic icebergs

April Flowers for redOrbit.com - Your Universe Online Summer and winter on the Antarctic shore are drastically different. Winters are dark and frozen, while summers are characterized by bright, clear waters, thick with algae and drifting icebergs. Over the last 20 years of warming, however, the region has experienced massive losses of sea ice in the winter that has allowed icebergs to roam freely for most of the year. A new study from the British Antarctic Survey demonstrates how...

Thwaites Glacier
2014-05-12 13:27:19

redOrbit Staff & Wire Reports - Your Universe Online A rapidly melting region of the West Antarctic Ice Sheet appears to have reached an irreversible state of decline, meaning that nothing can be done to prevent the glaciers from melting into the sea, researchers from NASA and the University of California, Irvine claim in a new study. The researchers came to that conclusion after analyzing four decades worth of data on glaciers located in the Amundsen Sea sector of West Antarctica....

Antarctic minke whales

redOrbit Staff & Wire Reports - Your Universe Online Researchers have discovered the origins of a bizarre duck-like sound heard in winter and spring in the ocean around Antarctica and off Australia’s west coast. The sound – a series of low-pitched, repetitive pulses dubbed “bio-duck” – was first recorded more than half a century ago, but its source has eluded scientists, until now. Using acoustic recorders, researchers Denise Risch of NOAA's Northeast Fisheries Science...

New campaign aims for international cooperation to protect sentinel species WASHINGTON, April 22, 2014 /PRNewswire-USNewswire/ -- Penguin lovers around the world will unite to observe World Penguin Day on April 25th, and The Pew Charitable Trusts is joining the celebration by announcing the launch of the first global effort aimed at protecting penguins wherever they live. Eighteen species of penguin range from the cold of Antarctica to the equatorial heat of the Galapagos Islands....

Researchers Decipher Climate Paradox From The Miocene Using Complex Model Simulations
2014-04-14 12:34:00

AWI Scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have deciphered a supposed climate paradox from the Miocene era by means of complex model simulations. When the Antarctic ice sheet grew to its present-day size around 14 million years ago, it did not get colder everywhere on the Earth, but there were regions that became warmer. A physical contradiction? No, as AWI experts now found out, the expansion of the ice sheet on the Antarctic...

[ Watch The Video: Researchers Test Drones To Monitor Antarctic Ice ] National Science Foundation Boldly going where larger, human-piloted planes cannot, they promise to close a key gap in knowledge for climate modelers Scientists studying the behavior of the world's ice sheets--and the future implications of ice sheet behavior for global sea-level rise--may soon have a new airborne tool that will allow radar measurements that previously would have been prohibitively expensive or...

Japan Loses Against Australia, UN In Fight To Continue Annual Whaling
2014-03-31 14:48:05

Brett Smith for redOrbit.com - Your Universe Online Japan’s highly-contentious whaling campaign experienced a major setback on Monday when a United Nations court ruled that the island nation could no longer continue its annual whale hunt in the waters around Antarctica. The International Court of Justice ruled in favor of Australia, which had sued Japan and rejected that country’s argument that the whaling has been conducted mainly for scientific reasons. “The court concludes,...

Moss Still Lives After 1500 Years Buried In Antarctic Ice
2014-03-17 14:57:18

Brett Smith for redOrbit.com - Your Universe Online British researchers who typically study polar moss samples because they provide indications of past climate conditions have found that Antarctic moss can survive trapped under ice for over 1,500 years. While some plant material has been brought back to life after 20 years of being frozen, only microbes have been shown to be capable of thousand-year feats of revival; that is until now. "These mosses were basically in a very long-term...

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...
