Latest Extreme points of Earth Stories
An ambitious expedition to search for life in one of the world’s most remote regions has ended in failure early Christmas morning. Team members from the British Antarctic Survey (BAS) called off a project to drill through two miles of Antarctica’s ice sheet to reach Lake Ellsworth due to problems linking boreholes in the ice.
Three very large-scale, National Science Foundation-funded Antarctic science projects--investigating scientifically significant subjects as varied as life in extreme ecosystems, the fate of one of the world's largest ice sheets and the nature of abrupt global climate-change events--have recently each reached important technological milestones that will advance cutting-edge research.
A project more than 15 years in the making is about to become a reality for a group or scientists wanting to learn more about life deep below the Antarctic ice sheet.
While global warming has caused extensive melting of sea ice in the Arctic region in recent years, the opposite phenomenon has been occurring in Antarctica, and now experts believe they've discovered the reason why.
Over the past few years, researchers have consistently shown an overall decrease in the size of the Arctic ice cap—particularly during the summer months when the most melting occurs.
Scientists and flight crew members with Operation IceBridge, NASA's airborne mission to study Earth's changing polar ice, are beginning another campaign over Antarctica.
Part of NSF's International Polar Year research portfolio, the six-nation study indicates that shallow-water populations have little in common
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 Amundsen-Scott South Pole Station is a U.S. research facility based at the South Pole, in Antarctica. It is the southernmost continually inhabited place on the planet. Its name honors Roald Amundsen who reached the South Pole in December 1911, and Robert F. Scott who reached the South Pole in January 1912. The station was constructed in 1956 to support the International Geophysical Year in 1957. It has been continuously occupied since then. It currently lies within 330 feet of the...
Arctic Circle -- The Arctic (Land of the Midnight Sun) is the area around the earth's North Pole while antarctic is in South Pole. It includes parts of Russia, Alaska, Canada, Greenland, Lapland and Svalbard as well as the Arctic Ocean. The Arctic Circle is one of the five major circles of latitude that mark maps of the Earth. Everything north of this circle is known as the Arctic, and the zone just to the south of this circle is the Northern Temperate Zone. This is the parallel of...
