Surprising New Pathway For North Atlantic Circulation - heh not like GW nuts think!
Now, research led by oceanographers at Woods Hole Oceanographic Institution (WHOI) and Duke University have teased out a new piece of that puzzle, expanding our understanding of this circulation model.

Using field observations and computer models, the study shows that much of the southward flow of cold water from the Labrador Sea moves not along the deep western boundary current, but along a previously unknown path in the interior of the North Atlantic.
There are still things to be discovered? Who'd have thunk it!
"This new path is not constrained by the continental shelf. It's more diffuse," said Bower. "It's a swath in the wide-open, turbulent interior of the North Atlantic and much more difficult to access and study."

And since this cold southward-flowing water is thought to influence and perhaps moderate human-caused climate change, this finding may impact the work of global warming forecasters.
"La la lalalala I can't hear you!"
"This finding means it is going to be more difficult to measure climate signals in the deep ocean," Lozier said. "We thought we could just measure them in the Deep Western Boundary Current, but we really can't."
"Never mind!"
