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.

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
