Monash University Countries need to work together to ensure Antarctic research continues and key questions on the region are answered, researchers say. In an article published in Nature, 75 scientists along with policy makers in 22 countries have outlined what they see as the major priorities for Antarctic research over the next 20 years and beyond. In it they outline six priorities for Antarctic science – the most important scientific questions to be addressed in the region, as...

isotope anomalies in atmospheric sulfates
2014-08-06 02:00:54

Susan Brown, UC San Diego Anomalous isotopes trace Earth’s ancient atmosphere, past El Niño events and future climate Sulfur signals in the Antarctic snow have revealed the importance of overlooked atmospheric chemistry for understanding climate, past and future. Eruptions of huge volcanoes, the disruptive weather pattern known as El Niño, and a fire season from hell each left distinctive chemical marks in layers of snow excavated near the South Pole, researchers from the...

redOrbit Staff & Wire Reports - Your Universe Online Norwegian explorer Roald Amundsen might have been the first person to reach the South Pole, but an international team of scientists has discovered that he was actually beaten to his destination – by industrial air pollution. In research appearing in Monday’s edition of the Nature journal Scientific Reports, Joe McConnell of Nevada's Desert Research Institute (DRI) and his colleagues explain how data from 16 ice cores collected...

Antarctic fur seal
2014-07-25 03:30:27

British Antarctic Survey Genetic analysis of Antarctic fur seals, alongside decades of in-depth monitoring,* has provided unique insights into the effect of climate change on a population of top-predators. Published in Nature this week, the findings show that the seals have significantly altered in accordance with changes in food availability that are associated with climate conditions. Despite a shift in the population towards ‘fitter’ individuals, this fitness is not passing down...

antarctic sea ice extent
2014-07-23 02:00:24

European Geosciences Union (EGU) New research suggests that Antarctic sea ice may not be expanding as fast as previously thought. A team of scientists say much of the increase measured for Southern Hemisphere sea ice could be due to a processing error in the satellite data. The findings were published July 22 in The Cryosphere, a journal of the European Geosciences Union (EGU). Arctic sea ice is retreating at a dramatic rate. In contrast, satellite observations suggest that sea ice...

Study Reveals Links Between Antarctic Climate And Food Chain
2014-07-08 03:24:51

By David Malmquist, Virginia Institute of Marine Science A long-term study of the links between climate and marine life along the rapidly warming West Antarctic Peninsula reveals how changes in physical factors such as wind speed and sea-ice cover send ripples up the food chain, with impacts on everything from single-celled algae to penguins. The study, published in today’s issue of Nature Communications, is authored by Dr. Grace Saba, an alumna of William & Mary’s Virginia...

New Sea Level Threat Created From Changing Antarctic Winds
2014-07-07 03:55:30

Australian Research Council's Centre of Excellence for Climate System Science New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated. Changes to Antarctic winds have already been linked to southern Australia’s drying climate but now it appears they may also have a profound impact on warming ocean temperatures under the ice shelves along the coastline of West and East Antarctic....

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
2014-06-17 05:19:27

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...

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

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...
