Like the human orchestra, the North Atlantic Current is a large scale oscillator continually created and sustained by a multitude of lower level, smaller scale oscillators as well as being constrained by larger processes at higher levels.
The slowing of the North Atlantic Current can also be thought of as a consequence of semiotic corruption.
Purple colors show somewhat thinner LSW spreading northeast into the Irminger Basin east of Greenland, eastward via the North Atlantic Current into the Iceland Basin, and southwestward along the western boundary into the subtropical basin.
Recirculations associated with the Deep Western Boundary Current, the Gulf Stream, and the North Atlantic Current (an extension of the Gulf Stream) mix the LSW and Mediterranean waters, creating the intermediate thicknesses (blue colors) and temperatures (green colors) between the two sources.
"Every year North Atlantic currents
cause a vast amount of litter to be washed up on Pembrokeshire beaches.
In the July 2 Nature, Swingedouw and colleagues report that solar variations don't change circulation of North Atlantic currents
Dr Barbara Maher of the University of Lancaster mapped magnetic sediments on the ocean floor to test a model developed by Dr Grant Bigg of the University of East Anglia that shows that North Atlantic currents
can switch between two main states.
"If this continues, it could, in theory, disrupt the circulation of North Atlantic currents
and cause them to slow or eventually shut down.
This means that warm North Atlantic currents
flowed up into the Norwegian Sea in the past and that these incursions were strongest near the coast -- similar to modern-day current patterns, says Krissek.
