- Antarctic Waters Yield Hundreds of Species (MSNBC News)
"Carnivorous sponges, blind creepy-crawlies adorned with hairy antennae and ribbed worms are just some of the new characters found to inhabit the dark abysses of the Southern Ocean, an alien abode once thought devoid of such life."
- Antarctic Ice Shelf Breaking Up (UK.Reuters.com)
"An Antarctic ice shelf is on the brink of collapse with just a sliver of ice holding it in place, the latest victim of global warming that is altering maps of the frozen continent." 01-09
- An Organism Survives Antarctica, Maybe Mars (Time.com)
"Say what you will about the simple, uninteresting lives of microorganisms, they're tough little critters. You try surviving for a million and a half years without heat, food or sunlight and see how you do. A team of National Science Foundation researchers just discovered a species of Antarctic organisms that has accomplished exactly that — and the microbes' unlikely survival can tell us a lot not just about the adaptability of life on Earth, but the prospects for it on Mars." 04-09
- Antarctica Ice Melting (Time.com)
"According to a new report in Nature, glaciers are getting thinner all around the perimeter of Greenland, and in western Antarctica as well. It's not so much that they're melting, says lead author Hamish Pritchard, of the British Antarctic Survey; it's that their seaward motion is accelerating. And, says Pritchard, 'that's a much more rapid way of losing ice than through melting alone.' " 2-06
- Antarctic Ice Melting Faster than Expected (Time.com)
"We already know that Arctic ice is melting faster than expected, and that sea level rise will likely bust the IPCC predictions. Now, thanks to a new paper published yesterday in Nature Geoscience, we have a better idea of why. Researchers from the British Antarctic Survey (BAS) and Columbia University's Lamont-Doherty Earth Observatory examined the Pine Island Glacier in West Antarctica—one of the frozen continent's largest glaciers—and found that it was melting more than 50% faster than it had been just 15 years ago, when an earlier group of scientists visited it. The glacier is now losing 80 cu. km of ice a year, up from 50 cu. km in 1994." 06-11

Uses colors to show the flow of ice. Pictures were collected and compiled from satellite images. 02-12
- -First-Ever Discovery of Whale Bones on the Antarctic Seafloor (New.Yahoo.com)
"For the first time ever, scientists say they have discovered a whale skeleton on the ocean floor near Antarctica. Resting nearly a mile below the surface, the boneyard is teeming with strange life, including at least nine new species of tiny of deep-sea creatures, according to a new study." 03-13

- Earth Climate History Through Ice Caps (PBS.org)
Provides graphs and explanations of climate changes, as well as greenhouse gases, radioactivity, and other measures. Shows that climate over the past ten thousand years has been very stable compared to the time before. Uses ice cores from Antarctica to determine past climate. 3-01
- New Underwater Volcano Found (Bloomberg.com)
"A previously unknown underwater volcano has been discovered off the coast of Antarctica, the National Science Foundation said Thursday." 5-04
- Southern Ocean (Wikipedia.org)
"The Southern Ocean is the body of water encircling the continent of Antarctica. It is the world's fourth-largest body of water, and the latest to be defined as an Ocean, having been accepted by a decision of the International Hydrographic Organization in 2000, though the term has long been traditional among mariners. Prior to that, the Atlantic, Pacific and Indian Oceans were considered to extend to Antarctica." 10-04
- -07-17-05 Ice Shelf Collapse Reveals Extreme Life Forms (MSNBC News)
"The collapse of a giant ice shelf in Antarctica has revealed a thriving ecosystem half a mile below the sea."
"Despite near freezing and sunless conditions, a community of clams and a thin layer of bacterial mats are flourishing in undersea sediments."
"Since light could not penetrate the ice or water, these organisms do not use photosynthesis to make energy. Instead, these extreme creatures get their energy from methane, Domack said today." 7-05
- Food Chain in Oceans Threatened (Time.com)
"Rising carbon dioxide in the atmosphere is threatening to make oceans too corrosive for marine organisms to grow protective shells, according to researchers."
"If emissions continue unabated, the entire Southern Ocean, which stretches north from the Antarctic coastline, and subarctic regions of the Pacific Ocean will soon become so acidic that the shells of marine creatures will soften and dissolve making them easy targets for predators. Others will not be able to grow sufficient shells to survive."
"The loss of shelled creatures at the lower end of the food chain could have disastrous consequences for larger marine animals." 9-05
- -12-11-05 Ice Core Extends Climate Record 650,000 Years (Scientific American)
"Researchers have recovered a nearly two-mile-long cylinder of ice from eastern Antarctica that contains a record of atmospheric concentrations of carbon dioxide (CO2) and methane--two potent and ubiquitous greenhouse gases--spanning the last two glacial periods. Analysis of this core shows that current atmospheric concentrations of CO2--380 parts per million (ppm)--are 27 percent higher than the highest levels found in the last 650,000 years." 12-05
- Thermohaline Conveyor Currents (GRID-Arendal)
"The global conveyor belt thermohaline circulation is driven primarily by the formation and sinking of deep water (from around 1500m to the Antarctic bottom water overlying the bottom of the ocean) in the Norwegian Sea. This circulation is thought to be responsible for the large flow of upper ocean water from the tropical Pacific to the Indian Ocean through the Indonesian Archipelogo. The two counteracting forcings operating in the North Atlantic control the conveyor belt circulation: (1) the thermal forcing (high-latitude cooling and the low-latitude heating) which drives a polar southward flow; and (2) haline forcing (net high-latitude freshwater gain and low-latitude evaporation) which moves in the opposite direction. In today's Atlantic the thermal forcing dominates, hence, the flow of upper current from south to north."
Provides a global chart of the flow of the currents.
"When the strength of the haline forcing increases due to excess precipitation, runoff, or ice melt the conveyor belt will weaken or even shut down." 01-06

"For the first time, scientists have confirmed Earth is melting at both ends, which could have disastrous effects for coastal cities and villages."
"Antarctica has been called 'a slumbering giant' by a climate scientist who predicts that if all the ice melted, sea levels would rise by 200 feet. Other scientists believe that such a thing won't happen, but new studies show that the slumbering giant has started to stir." 03-06
