Only 8 percent of the RAFOS
floats followed the Deep Western Boundary Current, or DWBC--"a remarkably low number in light of the expectation that the DWBC is the dominant pathway for Labrador Sea Water," the researchers wrote in Nature.
In this experiment, 40 subsurface RAFOS
floats are being launched in the Mediterranean Undercurrent south of Portugal over a six-month period, at the rate of two per week.
We will be setting more than 200 floats, mostly of a variety known as RAFOS
floats developed originally by Tom Rossby at the University of Rhode Island and now commercially produced in North Falmouth, MA.
