Melting glaciers create noisiest places in ocean, study says

Posted by External 16 minutes ago General
http://feeds.sciencedaily.com — Researchers measure underwater noise in Alaskan and Antarctic fjords and find them to be the noisiest places in the ocean. This leads researchers to ask how animals such as whales and seals use the noise and what will happen to fjord ecosystems once the glaciers recede and the noise disappears. Read More

Combined Arctic ice observations show decades of loss

Posted by External 3 days ago General
http://www.enn.com — It's no surprise that Arctic sea ice is thinning. What is new is just how long, how steadily, and how much it has declined. University of Washington researchers compiled modern and historic measurements to get a full picture of how Arctic sea ice thickness has changed. The results, published this month in The Cryosphere, show a thinning in the central Arctic Ocean of 65 percent between 1975 Read More

How did Emperor Penguins survive the last ice age?

Posted by External 4 days ago General
http://www.enn.com — The study of how climate change has affected emperor penguins over the last 30,000 years found that only three populations may have survived during the last ice age, and that the Ross Sea in Antarctica was likely the refuge for one of these populations.The findings, published in the journal Global Change Biology, suggest that while current climate conditions may be optimal for emperor penguins, Read More

http://feeds.sciencedaily.com — A study of how climate change has affected emperor penguins over the last 30,000 years found that only three populations may have survived during the last ice age, and that the Ross Sea in Antarctica was likely the refuge for one of these populations. The Ross Sea is likely to have been a shelter for emperor penguins for thousands of years during the last ice age, when much of the rest of Antarct Read More

Submarine data used to investigate turbulence beneath Arctic ice

Posted by External 7 days ago General
http://feeds.sciencedaily.com — Using recently released Royal Navy submarine data, researchers have investigated the nature of turbulence in the ocean beneath the Arctic sea-ice. Recent decreases in Arctic sea ice may have a big impact on the circulation, chemistry and biology of the Arctic Ocean, due to ice-free waters becoming more turbulent. By revealing more about how these turbulent motions distribute energy within the oce Read More

Himalayan ice shows chemicals ban is working

Posted by External 9 days ago General
http://feeds.sciencedaily.com — A unique study of frozen ice cores from the Tibetan Himalayas has shown that international agreements on phasing out the use of toxic persistent organic pollutants are working. "Chemical residues are carried thousands of miles on the prevailing winds and deposited in the ice. Ice cores are very effective barometers of pollution over time as ice is laid down over the decades," authors explain. Read More
