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...

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"...

Most research initiatives aim to discover more knowledge. The International Polar Year (IPY) went even further; it created more discoverers. That is what Canadian Arctic researcher David Hik will tell this week's meeting of the American Association for the Advancement of Science (AAAS) in Vancouver. "For the first time in the 130-year history of international polar years, people living in polar regions were not just objects of study – they led studies," said Hik. "This was the...

WASHINGTON, Aug. 18, 2011 /PRNewswire-USNewswire/ -- NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica. The map, which shows glaciers flowing thousands of miles from the continent's deep interior to its coast, will be critical for tracking future sea-level increases from climate change. The team created the map using integrated radar observations from a consortium of international satellites. (Logo:...

Amundsen Sea Polynya International Research Expedition (ASPIRE) Combines Research and Education In a unique and complex example of "science diplomacy," teams of U.S. and Swedish scientists are sailing this month aboard two research vessels to study the ecology of the Amundsen Sea, one of the least-explored and most productive bodies in Antarctic waters, and to gauge the potential effects of a changing climate on the Southern Ocean. The joint American and Swedish expedition, involving the U.S....

An award-winning new website is using realtime imagery from ESA's Envisat satellite to provide a wealth of information on sea ice to aid safe passage through the treacherous waters of the Antarctic. Although remote, the Southern Ocean is an increasingly busy route for sea traffic. These seas are used more and more to conduct scientific research, transport freight, harvest fertile fishing grounds and carry tourists to experience one of Earth's last wildernesses. However, ever-changing pack ice...

As Arctic sea-ice recedes inexorably towards another record summer minimum, scientists have highlighted the exceptional contribution that satellites have made to the International Polar Year and charting the effects of climate change. Celebrating the remarkable accomplishments of the International Polar Year (IPY), the IPY Oslo Science Conference last week drew together 2400 researchers, educators and members of northern communities "“ making it the biggest polar science meeting ever...

Scientists have announced that climate change is transforming the Arctic environment faster than expected and accelerating the disappearance of sea ice. The research involved over 370 scientists from 27 countries who spent 15 months aboard a research vessel above the Arctic Circle.  This was the first time a ship stayed mobile in Canada's high Arctic for an entire winter. "(Climate change) is happening much faster than our most pessimistic models expected," David Barber, a professor at...

Arctic and Antarctic research teams pulled back to warmer climates when the International Polar Year wrapped last March. But the call has gone out for a return to the poles for a more focused investigation into the effects of global warming. Leading the charge back to the Canadian Arctic is David Hik, a University of Alberta biology professor and a lead researcher with IPY. "IPY gave us a great snapshot of the state of the planet's polar regions," said Hik. "But in the Arctic we made many...

Hundreds of images derived from classified data that could be used to better understand rapid loss and transformation of Arctic sea ice should be immediately released and disseminated to the scientific research community, says a new report from the National Research Council.  The committee that wrote the report emphasized that these Arctic images show detailed melting and freezing processes and also provide information at scales, locations, and time periods that are important for...
