Freshwater is accumulating in the Arctic Ocean A simulated red dye tracer released in the Arctic Ocean shows freshwater transport. Freshwater is accumulating in the Arctic Ocean. The Beaufort Sea, which is the largest Arctic Ocean freshwater reservoir, has increased its freshwater content by 40% over the past two decades. How and where this water will flow into the Atlantic Ocean is important for local and global ocean conditions. A U.S. National Science Foundation-funded ...

A smashing discovery Article by Tracey Bryant, adapted from IceCube collaboration Photos courtesy of Frank Schroeder and the IceCube Collaboration March 10, 2021 IceCube detector helps prove 60-year-old theory An electron antineutrino races to Earth from outer space at nearly the speed of light, carrying 6.3 petaelectronvolts (PeV) of energy. Deep in the ice sheet at the South Pole, this high-energy particle smashes into an electron and prod...

Oak Ridge Today Posted at Praveena Krishnan The National Science Foundation Office of Polar Programs has awarded ORAU a collaborative research grant to study greenhouse gas emissions in the Arctic. The award is valued at $581,829. The grant will be used to study local and regional emissions of isotopes of methane and carbon dioxide. Methane and carbon dioxide are two greenhouse gases. Greenhouse gases can help raise the Earth’s temperature, changing the climate and causing other significan...
