The Hunter's Breath tells a story of adventure and discovery in Antarctica

SANTA CRUZ, CA--In six trips to Antarctica, biologist Terrie Williams endured brutal conditions on the coldest, driest, windiest continent on Earth in order to learn the secrets of the mysterious Weddell seals, the only wild mammals capable of surviving Antarctic winters. In her new book, The Hunter's Breath, Williams interweaves two amazing stories from those expeditions: One is the story of the...

Explanation offered for Antarctica's 'blood falls'

COLUMBUS, Ohio Researchers here have discovered that a reddish deposit seeping out from the face of a glacier in Antarcticas remote Taylor Valley is probably the last remnant of an ancient salt-water lake.

Facing extreme ice conditions, coast guard, NSF deploy second icebreaker to Antarctica

Extremely unusual ice conditions at McMurdo Station, the National Science Foundation's (NSF) logistics and science hub in Antarctica, will require two Coast Guard icebreakers to ensure that resupply and refueling ships can reach the station. ... Al Sutherland, ocean projects manager in NSF's Office of Polar Programs, said the ice extends almost three times farther out from the station than...

AAAS at the BA: Whale food, winners and losers in Antarctica and solar insights

...........................9 SEPTEMBER 2002- The latest thinking on the chances of extinction for Antarctic animals in seas and lakes, whale food hiding beneath sea ice, and new insights on the Sun's spin are among the hot topics slated for discussion at today's Frontiers of Polar Science panel, organized by the American Association for the Advancement of Science (AAAS), through its journal ......

Frozen 'lake' beneath Antarctica ideal to test sterile drilling techniques

Berkeley - Measurements of the ice temperature far below the South Pole suggest that a so-called "lake" discovered at the base of the ice is most likely permafrost - a frozen mixture of dirt and ice - because the temperature is too low for liquid water....... Far from being a disappointment, says a University of California, Berkeley physicist, the permafrost subglacial lake may be ideal for devel...

'Mercury sunrise' phenomenon found in Antarctica

In just five months during the spring each year, the northernmost coast of Alaska, a region that includes the Arctic National Wildlife Refuge, receives more than double the amount of mercury that falls on the northeastern United States in a year. New research now shows a similar phenomenon also occurs each year in the Antarctic the first time its been reported in the South Polar Region. ... ...T...

Research season will feature use of sophisticated technologies to map Antarctica

Researchers plan to map the surface of the vast Antarctic ice sheet with airborne radar, measure the movement of the Earth's crust beneath the ice with Global Positioning System transceivers and deploy buoys to explore the waters off the Antarctic Peninsula when the U.S. Antarctic Program's 2001-2002 research season gets underway next month.... ..."For almost 50 years, the United States has been...

Marine biology course uses Antarctica as its classroom

Scientists have become so alarmed that they are pressing.for international agreement on a wide-ranging set of measures designed to keep.the continent free of dangerous pathogens. . The proposals, adopted last week in Hobart, Tasmania, at a gathering of.50 Antarctic specialists, will be presented...

New Dinosaur Finds In Antarctica Paint Fuller Picture Of Past Ecosystem

A team of Argentinean and U.S. scientists has found fossils of a duck-billed dinosaur, along with.remains of Antarctica's most ancient bird and an array of giant marine reptiles, on Vega Island off.the eastern side of the Antarctic Peninsula. .The tooth of a duck-billed dinosaur, or hadrosaur, was found in sands about 66-67 million years.old, from the Cretaceous period (about 1-2 million year...
