Image 1 - Antarctic Expedition Checks CryoSat Data
2011-12-10 04:41:07

Next week marks 100 years since Roald Amundsen reached the South Pole. As a team of scientists brave the Antarctic to validate data from ESA´s CryoSat mission, it´s hard to imagine what these first intrepid explorers would have thought of today´s advances in polar science. The remote and vast expanse of the Antarctic is arguably the most hostile environment on Earth — infamously claiming the lives of Captain Robert Scott and his party all those years ago in their fated...

Accelerated melting of two fast-moving outlet glaciers that drain Antarctic ice into the Amundsen Sea Embayment is likely the result, in part, of an increase in sea-surface temperatures in the tropical Pacific Ocean, according to new University of Washington research. Higher-than-normal sea-level pressure north of the Amundsen Sea sets up westerly winds that push surface water away from the glaciers and allow warmer deep water to rise to the surface under the edges of the glaciers, said...

The end of the last ice age and the processes that led to the melting of the northern and southern ice sheets supply basic information on changes in our climate. Although the maximum size of the ice sheet in the northern hemisphere during the last ice age is relatively well known, there is little reliable data on the dimensions of the Antarctic ice sheet. A publication appearing in the journal “Science” on 1 December now furnishes indications that the two hemispheres attained...

Radiocarbon bomb pulse revelations One hundred years ago, two teams of explorers raced to be the first to reach the South Pole. Roald Engelbregt Gravning Amundsen reached the South Pole on December 14, 1911. Thirty-three days later on 17 January 1912 the Terra Nova Expedition led by Robert Falcon Scott arrived at the Pole in second place. At the same time in East Antarctica, the Australasian Antarctic Expedition led by Douglas Mawson was searching for the South Magnetic Pole. On...

Operation IceBridge: Watching The Birth Of An Iceberg
2011-11-03 04:41:08

[ Watch the Video ] After discovering an emerging crack that cuts across the floating ice shelf of Pine Island Glacier in Antarctica, NASA's Operation IceBridge has flown a follow-up mission and made the first-ever detailed airborne measurements of a major iceberg calving in progress. NASA's Operation Ice Bridge, the largest airborne survey of Earth's polar ice ever flown, is in the midst of its third field campaign from Punta Arenas, Chile. The six-year mission will yield an...

Researchers Brave Bone Chilling Cold To Solve Geologic Mysteries
2011-11-01 10:03:48

[ Watch the Video ] Geologist John Goodge looks for clues about Antarctica's past in the 2 percent of the continent that is not covered in ice! The University of Minnesota-Duluth professor has been visiting Antarctica since 1985, finding and studying rocks that help tell the story of how this desolate continent has formed and changed over time. In late 2010 and early 2011, he spent several weeks in the field, with other scientists, visiting a dozen sites along 1,200 miles of...

Antarctic Killer Whales Seek Spa-like Relief In The Tropics
2011-10-27 04:43:23

NOAA researchers offer a novel explanation for why a type of Antarctic killer whale performs a rapid migration to warmer tropical waters in a paper published this month in the science journal Biology Letters. One tagged Antarctic killer whale monitored by satellite traveled over 5,000 miles to visit the warm waters off southern Brazil before returning immediately to Antarctica just 42 days later. This was the first long distance migration ever reported for killer whales. "The whales are...

New Data Shows Antarctic Ozone Hole Still Remains
2011-10-20 13:06:41

[ Watch the Video ] The Antarctic ozone hole, which yawns wide every Southern Hemisphere spring, reached its annual peak on Sept. 12. It stretched to 10.05 million square miles, the ninth largest ozone hole on record. Above the South Pole, the ozone hole reached its deepest point of the season on Oct. 9, tying this year for the 10th lowest in this 26-year record. NASA and the National Oceanic and Atmospheric Administration (NOAA) use balloon-borne instruments, ground-based instruments...

CFC's the Real Reason for Ozone Loss?
2011-10-13 03:04:52

Op/ed By Kevin Roeten (roetenks@charter.net) How many individuals and corporations have lost money and jobs over theoretical ozone depletion? Why have natural variations never been considered as a possible reason for seasonal ozone loss? With ozone (O3) depletion, millions were (and are) convinced that chlorofluorocarbons (CFC´s), and certain brominated compounds (Halons), were responsible. Due to their theorized Ozone Depletion Potential (ODS), the most stable non-toxic refrigerants,...

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...
