Deep convection, or mixing, of ocean waters in the North Atlantic, widely thought to occur in only the Labrador Sea and the Mediterranean, may occur in a third location first proposed nearly 100 years ago by the explorer and oceanographer Fridtjof Nansen. The findings, reported this week in the journal Nature, may alter thinking about the oceans overturning circulation that affects earths climate.
An international team of scientists reports in Nature that convection, a process that forms deep waters of the worlds oceans and plays a major role in the climate system, may also be occurring in the Irminger Sea east of Greenland because of a sporadic and localized atmospheric phenomenon known as the Greenland tip jet.
Lead author Robert Pickart of the Woods Hole Oceanographic Institution (WHOI) says the study places an additional complexity to the climate puzzle that must now be taken into account in observations and models, and that the implications of an additional source of Labrador Sea Water are far-reaching.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
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...
