When internal waves up to 300 feet first form they cause a mighty churning of ocean waters – something invisible to and unfelt by anyone at the surface.
Maps, the first of their kind, show energy of internal waves carried away from where they originated. The larger and longer the arrows (vectors) the more energy is being carried away from where the waves originated. The upper map shows that, in general, internal waves generated by storms move through the ocean depths toward the mid-latitudes. The lower maps shows energy moving directly away from places where tidal forces have created internal waves.Graphic credit required: University of Washington/Nature
Now in a novel use of mooring data, some of it three decades old, a University of Washington researcher has calculated just how much punch these waves appear to carry as they travel, or propagate, thousands of miles from where they originate.
Its energy that appears to be crucial to the conveyor-belt-like circulation wherein millions of cubic meters of icy-cold water sink each second at high latitudes and are driven to upwell at lower latitudes. Without such upwelling, global ocean circulation would stall, causing the entire ocean to fill with cold water. Further, nutrients that have drifted down to the ocean depths would remain in the deep instead of being carried back to surface waters for use by plankton, the tiny plants and animals on which all other marine life depend and which greatly affect how much carbon dioxide is absorbed and released by the oceans.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
