FINDING THE SPOT
“They’ll have to work with flotsam,” he said. “You get the wind and current data and work back. You have to distinguish between the light material that is on the surface and exposed to the wind, and the buoyant material, which is floating, but just under the surface and not exposed to the winds.”
Chris German, the chief scientist for the deep submergence group at the Woods Hole Oceanographic Institute on Cape Cod, said that even with two debris fields located miles apart, the backtracking can be done.
“You look at the ocean currents and wind and determine where the debris was 10 hours before, then 10 hours before that. You do that all the way back to when you think the crash occurred.” Fish said that the hindcasting could trace out the path up to 30 days back in time
