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,...

Scientists To Study Underground Lake In Antarctica
2011-10-11 09:43:06

An Antarctic lake hidden under 1.8 miles of ice in the western region of the continent could reveal what life on Earth looked like a million years ago and could narrow down the search for extraterrestrial life, as well as give scientists clues to future climate impacts, according to a British expedition taking up the study. Expedition members will use hot water to melt down through the nearly 2-mile-thick ice to reach Lake Ellsworth, which has been isolated from the outside world for more...

HAMPTON, Va., Oct. 2, 2011 /PRNewswire-USNewswire/ -- A NASA-led study has documented an unprecedented depletion of Earth's protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere. (Logo: <font size="2" face="Arial">http://photos.prnewswire.com/prnh/20081007/38461LOGO</font> ) The study, published online Sunday in the journal Nature, finds the amount of ozone destroyed in the Arctic...

Image 1 - 50-million-year-old Clam Shells Hint At Future Of El Niño Phenomenon
2011-09-20 04:44:31

  Earth warming will presumably not lead to a permanent El Niño state in the South Pacific Ocean. This is the conclusion drawn by an international team of researchers after it investigated 50-million-year-old clam shells and wood from the Antarctic. The growth rings of these fossils indicate that there was also a climate rhythm over the South Pacific during the last prolonged interglacial phase of the Earth´s history resembling the present-day interplay of El...

WASHINGTON, Aug. 18, 2011 /PRNewswire-USNewswire/ -- NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica. The map, which shows glaciers flowing thousands of miles from the continent's deep interior to its coast, will be critical for tracking future sea-level increases from climate change. The team created the map using integrated radar observations from a consortium of international satellites. (Logo:...

A NASA scientist and her colleagues were able to observe for the first time the power of an earthquake and tsunami to break off large icebergs a hemisphere away. Kelly Brunt, a cryosphere specialist at Goddard Space Flight Center, Greenbelt, Md., and colleagues were able to link the calving of icebergs from the Sulzberger Ice Shelf in Antarctica following the Tohoku Tsunami, which originated with an earthquake off the coast of Japan in March 2011. The finding, detailed in a paper published...

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...
