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...

Arctic Crustaceans Survive Ice Melt By Migrating Via Deep Ocean Currents
2012-09-14 11:29:59

Brett Smith for redOrbit.com - Your Universe Online As climate change tightens its grip on the polar regions, many biologists are investigating how different species that live there are being affected by increasing temperatures and decreasing polar ice. Some arctic crustaceans are showing why they have persisted for millions of years by adapting to the changes in their environment, according to a new report published in the journal Biology Letters by an international team of scientists....

Antarctic Expedition Looks For Life In Lake Under Ice Sheet
2012-09-10 13:12:21

Brett Smith for redOrbit.com - Your Universe Online A team of 12 British scientists are about to embark on a grueling two-and-a-half month expedition to search for life in Lake Ellsworth, which is located 1.6 miles below the surface of the Antarctic ice sheet. The British Antarctic Survey expedition, which also aims to find out the overall stability of the ice sheet, will be closely observed by NASA as a model for future space missions to the icy moons of Jupiter where it is believed...

Arctic Sea Ice Expected To Hit Record Low Soon
2012-08-22 07:46:38

April Flowers for redOrbit.com - Your Universe Online Sea ice in the Arctic Ocean is likely to hit its lowest next week and then keep on shrinking. Scientists at the U.S. National Snow and Ice Data Center say data shows that the sea ice coverage is tracking below the previous record low, set in 2007. Arctic sea ice extent during the first two weeks of August continues to track below the 2007 record low daily ice extents. As of August 13, ice extent is already among the four lowest...

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...
