Deep Sea Currents may be Slowed by Climate Change
2014-03-21 22:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Deep ocean currents may be slowing down due to climate change, according to a new study. Ocean currents act as conveyor belts that channel heat, carbon, oxygen and other nutrients around the world's seas, and the slowdown of deep sea currents is worrisome, scientists say. "Our observations are showing us that there is less formation of these deep waters near Antarctica," said Irina Marinov, a climate scientist at the University of Pennsylvania. "This is worrisome because, if this is the case,...
The illusory calm of Australia's deadly ocean currents

BBC: Researchers in Australia have declared treacherous ocean currents the nation's deadliest natural hazard ahead of bushfires and floods. Rip currents are strong, narrow channels that pull the unwitting away from the shore and some move faster than an Olympic swimmer. "The way they work on surf beaches, the white water - the breaking waves - bring water to the beach," said Rob Brander, a geomorphologist -someone who studies the way the ocean and the land interacts - at the University of New South...

How Earths rotation affects vortices in nature, such as hurricanes and ocean currents
2013-10-15 16:59:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: What do smoke rings, tornadoes and the Great Red Spot of Jupiter have in common? They are all examples of vortices, regions within a fluid (liquid, gas or plasma) where the flow spins around an imaginary straight or curved axis. Understanding how geophysical (natural world) vortices behave can be critical for tasks such as weather forecasting and environmental pollution monitoring. In a new paper in the journal Physics of Fluids, researchers Junho Park and Paul Billant of the CNRS Laboratoire...
