Polar Bear Diets Change Climate Change
2014-01-23 13:03:52

Lee Rannals for redOrbit.com - Your Universe Online Polar bears are able to switch up their diet in order to help them survive the warming Arctic, according to a new study. Scientists at the American Museum of Natural History performed a three-part study that shows how polar bears switch up plant and animal food sources as they face the changing climate. Arctic sea ice is beginning to melt earlier and freezing later each year, so polar bears are having a limited amount of time to hunt...

Slight changes in the timing of the annual loss of sea-ice in polar regions could have dire consequences for polar ecosystems, by allowing a lot more sunlight to reach the sea floor. The research by scientists at UNSW and the Australian Antarctic Division predicts that biodiversity on some areas of the polar seabed could be reduced by as much as one third within decades, as the poles warm. The study, Light-driven tipping points in polar ecosystems, will be published in the journal...

Different Genetic Mechanisms Used By Antarctic and Arctic Insects To Cope With Lack of Water
2013-03-13 08:00:08

National Science Foundation Although they live in similarly extreme ecosystems at opposite ends of the world, Antarctic insects appear to employ entirely different methods at the genetic level to cope with extremely dry conditions than their counterparts that live north of the Arctic Circle, according to National Science Foundation- (NSF) funded researchers. Writing in the Proceedings of the National Academy of Sciences, the researchers concluded, "Polar arthropods have developed...

Autonomous Machine Makes Over-ice Travel Safer
2013-03-04 11:09:54

National Science Foundation A century after Western explorers first crossed the dangerous landscapes of the Arctic and Antarctic, researchers funded by the National Science Foundation (NSF) have successfully deployed a self-guided robot that uses ground-penetrating radar to map deadly crevasses hidden in ice-covered terrains. Deployment of the robot--dubbed Yeti--could make Arctic and Antarctic explorations safer by revealing unseen fissures buried beneath ice and snow that could...

Antarctica’s Halley VI Now Open For Business
2013-02-05 18:39:33

Lee Rannals for redOrbit.com — Your Universe Online A new scientific research facility in Antarctica has now officially opened, helping to bring a modern twist to adventuring to the most southern part of our world. The Antarctic Research Station has opened 100 years after Captain Robert Falcon Scott's Antarctica expeditions, replacing the 20-year-old Halley V facility. The Halley VI Research Station is the sixth to be built on the floating Brunt Ice Shelf, the first station...

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...

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....

Today the U.S. National Research Council released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions. University of Massachusetts Amherst geosciences researcher and expert in the paleoclimate of the Arctic, Julie Brigham-Grette, co-chaired the NRC report, "Lessons and Legacies of the IPY 2007-08"...

Europe Hammered By Winter, Is North America Next?
2012-02-18 04:40:38

For the first half of this year's winter, the big news was warm temperatures and lack of snow. Ski resorts were covered in bare dirt, while January temperatures in southern California topped July highs. Then, out of the blue, Europe got clobbered: Over the past two weeks, temperatures in Eastern Europe have nose-dived to -30 degrees Celsius (-22 degrees Fahrenheit). Blizzards and the bone-chilling cold have resulted in the deaths of over 550 people so far, with rooftop-high snow drifts...
