Research at Greenland and Antarctic shows decline in methane and ethane levels Recent data from NSF-funded research in both Greenland and Antarctica demonstrate that fossil-fuel related emissions of both methane and ethane, two of the most abundant hydrocarbons in the atmosphere, declined at the end of the twentieth century, according to a paper published Thursday in the journal Nature. The causes of the decline in methane emission rates to the atmosphere have been puzzling scientists for...

Ice and frozen ground at the North and South Poles are affected by climate change induced warming, but the consequences of thawing at each pole differ due to the geography and geology, according to a Penn State hydrologist. "The polar regions, particularly the Arctic, are warming faster than the rest of the world," Michael N. Gooseff, associate professor of civil and environmental engineering, told attendees today (Aug. 11) at the 96th annual meeting of the Ecological Society of America in...

The Earth was a much different place 1.1 billion years ago. Researchers are discovering strong evidence that parts of what are now Texas and Antarctica were connected, according to Staci Loewy, a geochemist at California State University, Bakersfield. "I can go to the Franklin Mountains in West Texas and stand next to what was once part of Coats Land in Antarctica," says Loewy, "That's so amazing." Long before the supercontinent Pangaea formed, there were other landforms bouncing around on...

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...

Bt Jill Sakai, University of Wisconsin-Madison During the last prolonged warm spell on Earth, the oceans were at least four meters "“ and possibly as much as 6.5 meters, or about 20 feet "“ higher than they are now. Where did all that extra water come from? Mainly from melting ice sheets on Greenland and Antarctica, and many scientists, including University of Wisconsin-Madison geoscience assistant professor Anders Carlson, have expected that Greenland was the main culprit. But...

Blue Ribbon Panel to Assess U.S. Activities on World's Southernmost Continent Norm Augustine, the former Chair of the National Academy of Engineering, will lead an upcoming strategic review of U.S. science-support operations on the continent of Antarctica and the Southern Ocean the Office of Science and Technology Policy (OSTP) and National Science Foundation (NSF) announced today. Augustine, who served on the President's Council of Advisors on Science and Technology during both Democratic...

Fresh research into glaciers could help scientists better predict the impact of changing climates on global sea levels Fresh research into glaciers could help scientists better predict the impact of changing climates on global sea levels. Scientists have shown for the first time that the terrain beneath glaciers influences how much glacier melt contributes to fluctuations in sea levels. Researchers say the study will improve their understanding of how ice sheet movements have affected sea...

Sea levels could be rising faster than scientists originally believed, thanks to the warming subsurface waters that could cause more rapid melting of ice sheets in Greenland and Antarctica, researchers from the University of Arizona are claiming. In a new study, University of Arizona Assistant Professor of Geosciences Jianjun Yin and colleagues analyzed 19 different climate models under which global warming would accelerate the melting of the world's largest ice sheets over the next two...

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...

Ross Seal, Ommatophoca rossii
2013-01-01 15:44:30

The Ross seal (Ommatophoca rossii) is a true seal in the Phocidae family, and can only be found on pack ice in Antarctica. This species was formally described by James Clark Ross in 1841, during his British Antarctic Expedition. It is very uncommon to see in its range and rarely leaves the pack ice, with stray individuals occurring off southeast Australia or sub-Antarctic islands. The Ross seal can reach an average length between 5.5 and 6.9 feet, although some females can reach up to 8.2...

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...

2012-04-02 17:14:35

The Antarctic Silverfish, (Pleuragramma antarcticum), is a member of the Notothenioidei family of fish. It is widely distributed around the Antarctic, but has largely disappeared from the western side of the northern Antarctic Peninsula based on 2010 research funded by the National Science Foundation. It is also found throughout the Southern Ocean. It grows to an average size of 6 inches, but has been known to reach lengths of up to 10 inches. It is usually pink with a silver tint, and...

Cryolophosaurus, meaning "cold crest lizard", is a genus of theropod dinosaur from the Early Jurassic Period (Pliensbachian Age). It is known from the Hanson Formation (previously known as the Upper Falla Formation). It was discovered by paleontologist Dr. William Hammer in 1991. It was the first carnivorous dinosaur to be discovered in Antarctica. It was also the first dinosaur from Antarctica to be officially named. Dr. William Hammer and his team unearthed the dinosaur during the...
