Climate Change Slowing Down Deep Ocean Conveyor Belt
2014-03-24 08:42:04

Katherine Unger Baillie, University of Pennsylvania Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe. A new study by the University of Pennsylvania’s Irina Marinov and Raffaele Bernardello and colleagues from McGill University has found that recent climate change may be acting to slow down one of these conveyer belts, with potentially serious consequences for the future of the planet’s climate....

Antarctic ice shelf

McGill University In the mid-1970s, the first available satellite images of Antarctica during the polar winter revealed a huge ice-free region within the ice pack of the Weddell Sea. This ice-free region, or polynya, stayed open for three full winters before it closed. Subsequent research showed that the opening was maintained as relatively warm waters churned upward from kilometers below the ocean's surface and released heat from the ocean's deepest reaches. But the polynya -- which...

Southern Ocean Sampling Shows Travels Of Marine Microbes

University of New South Wales By collecting water samples up to six kilometers below the surface of the Southern Ocean, UNSW researchers have shown for the first time the impact of ocean currents on the distribution and abundance of marine micro-organisms. The sampling was the deepest ever undertaken from the Australian icebreaker, RSV Aurora Australis. Microbes are so tiny they are invisible to the naked eye, but they are vital to sustaining life on earth, producing most of the...
