Warm water has penetrated the Arctic interior

Warm water has penetrated the Arctic interior

Science
Aug. 30 (UPI) -- Arctic ice faces a threat from within, according to a new study by researchers at Yale University. Scientists have identified a mass of "archived" heat trapped beneath the Arctic surface. The mass of warm water originated from hundreds of miles away, but has infiltrated the Arctic interior. "We document a striking ocean warming in one of the main basins of the interior Arctic Ocean, the Canadian Basin," Mary-Louise Timmermans, a professor of geology and geophysics at Yale, said in a news release. Over the last three decades, the amount of heat in the Canadian Basin's upper ocean has doubled. Timmermans and her colleagues traced the heat source to waters a few hundred miles south, where sea ice losses have left the surface of the ocean exposed to the summer sun. Arctic win...

Warm rock rising deep beneath New England, seismic study reveals

Science
Dec. 1 (UPI) -- Deep beneath New England, a giant mass of warm rock is slowly but steadily rising toward the surface. The revelation undermines some of what scientists thought they understand about plate tectonics and the geology of the mantle."The upwelling we detected is like a hot air balloon, and we infer that something is rising up through the deeper part of our planet under New England," researcher Vadim Levin, a geophysicist and professor at Rutgers University-New Brunswick, said in a news release.The mass of rock is not on the scale of Yellowstone. It measures a couple hundred miles across, and though it may one day form a new volcanic system, it is unlikely to yield an eruption for millions of years.Scientists were first alerted to something peculiar after noticing a temperature a...
Antarctica's warm underbelly revealed

Antarctica's warm underbelly revealed

Science
This is the best map yet produced of the warmth coming up from the rocks underneath the Antarctic ice sheet. This "geothermal heat flux" is key data required by scientists in order to model how the White Continent is going to react to climate change. If the rockbed's temperature is raised, it makes it easier for the ice above to move. And if global warming is already forcing change on the ice sheet, a higher flux could accelerate matters. The map was made by researchers at the British Antarctic survey and is published in the journal Geophysical Research Letters."The heat coming from the Earth’s interior is important to understand the overall conditions that control the dynamics at the base of the ice sheet and hence the ice flow,” explained Yasmina Martos, currently affiliated to the US sp

Warm waters off West Coast has lingering effects for salmon

Warm waters off West Coast has lingering effects for salmon

Technology
The mass of warm water known as "the blob" that heated up the North Pacific Ocean has dissipated, but scientists are still seeing the lingering effects of those unusually warm sea surface temperatures on Pacific Northwest salmon and steelhead. Federal research surveys this summer caught among the lowest numbers of juvenile coho and Chinook salmon in 20 years, suggesting that many fish did not survive their first months at sea. Scientists warn that salmon fisheries may face hard times in the next few years. Fisheries managers also worry about below average runs of steelhead returning to the Columbia River now. Returns of adult steelhead that went to sea as juveniles a year ago so far rank among the lowest in 50 years. Scientists believe poor ocean conditions are likely to blame: Cold-water...
