NASA Studies Antarctic Sea Ice
2012-11-14 19:43:13

Alan McStravick for redOrbit.com — Your Universe Online A new study by NASA and the British Antarctic Survey tries to explain the increase of ice cover in the Antarctic that is seemingly contrary to the effects of climate change that have been witnessed over the previous two decades. In their report, they purport they have the first direct evidence that this increase in sea ice cover is due to changing winds that have had an impact on the changes to Antarctic sea ice drift. The...

Global Warming Melting Vital Antarctic Airstrip
2012-10-25 14:23:46

Brett Smith for redOrbit.com - Your Universe Online The future of Australia´s once highly touted Wilkins airstrip, built to link the country with its research stations in Antarctica, is in jeopardy as warmer temperatures have caused the $46-million runway carved from glacial ice to soften and melt. The Australian government announced on Wednesday that it was looking at both temporary and permanent alternatives for supplying its research stations on the frozen continent. "There...

Ice Caps Grow and Shrink
2012-10-24 20:26:45

Brett Smith for redOrbit.com — Your Universe Online 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. However, a new study from NASA scientists has shown that this melt off around the Arctic is accompanied by the record expansion of sea ice around Antarctica, when the Southern Hemisphere is experiencing its colder temperatures of the year....

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. Now in its fourth year, IceBridge's return to the Antarctic comes almost a year after the discovery of a large rift in the continent's Pine Island Glacier. The first science flight of the campaign began Friday at 8 a.m. EDT when NASA's DC-8 research aircraft left Punta Arenas, Chile, for an 11-hour flight that will take it...

Composition Of Microbial Populations Determined By Freshwater Flows Into The Arctic And Southern Oceans
2012-10-11 08:05:22

Part of NSF's International Polar Year research portfolio, the six-nation study indicates that shallow-water populations have little in common Differing contributions of freshwater from glaciers and streams to the Arctic and Southern oceans appear to be responsible for the fact that the majority of microbial communities that thrive near the surface at the Poles share few common members, according to an international team of researchers, some of whom were supported by the National Science...

The Arctic is getting warmer and wetter. As temperatures rise and sea ice melts, scientists suspect that system feedback cycles may further speed up the warming process. Now, a new study out of the University of Colorado at Boulder is showing how shifting patterns of humidity may bring about changes in the Arctic atmosphere. The new study compiled data from the 1950s through the present to examine the subtle changes in the Arctic atmosphere over time. The team then incorporated the data...

ESA Satellites Taking A Deeper Look Into Sea Ice
2012-10-05 08:28:31

This year, satellites saw the extent of Arctic sea ice hit a record low since measurements began in the 1970s. ESA´s SMOS and CryoSat satellites are now taking a deeper look by measuring the volume of the sea-ice cover. Measurements from ESA´s Soil Moisture and Ocean Salinity (SMOS) mission show that ice has thinned significantly in the seasonal ice zones, with extensive areas less than half a metre thick. Sea ice has a large influence on the heat exchange between the ocean...

Roald Amundsen
2013-10-29 11:20:57

Roald Amundsen was a Norwegian explorer that was known for his expeditions into polar regions. He is best known for his discovery of the South Pole, being the first recognized explorer to reach the North Pole, and being the first explorer to travel along the Northwest Passage. He was born to Jens Amundsen and Hanna Sahlqvist in July of 1872. His family owned and managed a number of ships, but his mother did not want him to join the family trade, encouraging him to become a doctor. Amundsen...

Antarctica

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

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...
