New Twist On Arctic Melt Revealed By River Ice
2014-04-04 09:32:47

Simon Fraser University A new study led by Lance Lesack, a Simon Fraser University geographer and Faculty of Environment professor, has discovered unexpected climate-driven changes in the mighty Mackenzie River’s ice breakup. This discovery may help resolve the complex puzzle underlying why Arctic ice is disappearing more rapidly than expected. Lesack is the lead author on Local spring warming drives earlier river-ice breakup in a large Arctic delta. Published recently in Geophysical...

Brett Smith for redOrbit.com - Your Universe Online According to a new study from NASA researchers, warm river waters draining into the Arctic Ocean are adding to the melting of sea ice in the Arctic Ocean each summer. Published in the journal Geophysical Research Letters, researchers reported on an abrupt inflow of warm river water into the Arctic Ocean that swiftly warmed the top layers in the sea, fueling the melting of summer ice. “River discharge is a key factor contributing...

Watershed covers roughly 20 percent of Canada, including oil sands; The Mackenzie may discharge more water into the Arctic than the St. Lawrence into the Atlantic The governance of Canada's massive Mackenzie River Basin holds enormous national but also global importance due to the watershed's impact on the Arctic Ocean, international migratory birds and climate stability, say experts convening a special forum on the topic. "Relevant parties in western Canada have recognized the need for...

Canadian scientists say they have discovered brown grizzly bears are feeding on migrating broad whitefish in a Northwest Territories stream. Scientists from the University of Alberta say the discovery in the Mackenzie Delta region of the Northwest Territories has researchers advising increased care in petroleum extraction and infrastructure development within the area. Oliver Barker and Andrew Derocher, who led the study, said they observed at least one brown bear engaged in the unusual...

Scientists say they've found a much higher level of mercury flowing from Canada's Mackenzie River into the Arctic Ocean than found by previous studies. University of Alberta researcher Jennifer Graydon and her colleagues analyzed water in the Mackenzie River as it flowed north into the Beaufort Sea. She collected samples for three months and discovered the total amount of mercury exported from the river during that period was equal to an entire year's worth of mercury calculated in previous...

University of Alberta researchers conducting a water study in the Mackenzie River Delta have found a dramatically higher delivery of mercury from the Mackenzie River to the Arctic Ocean than determined in previous studies.Researcher Jennifer Graydon analyzed water in the Mackenzie River as it flowed north into the Beaufort Sea. She collected samples for three months and discovered the total amount of mercury exported from the river during that three-month period was equal to an entire year's...

CALGARY, Alberta (Reuters) - Public hearings into North America's first major Arctic gas pipeline will start next month and travel to communities throughout Canada's far North and elsewhere for nearly a year, regulators said on Tuesday. Epic regulatory and environment-impact proceedings for the C$7 billion ($6 billion) Mackenzie Gas project are slated to begin in the northern town of Inuvik, Northwest Territories, on January 25, the National Energy Board said. The environmental joint review...
