Why the slowing of the world’s fastest ocean current would mean big trouble
STRAITS OF FLORIDA — At 2 a.m., oceanographer Ryan Smith was headed into his 12th hour of work with little sleep when trouble started.
From the rear deck of the University of Miami’s research boat, he guided the vessel’s winch to lower a cage containing 14 long, gray tubes, collectively weighing about 1,000 pounds, hundreds of meters deep into the Atlantic Ocean, to record the temperature, salinity and density of the water. But after running smoothly for the first two-thirds of the trip, the sensors now suddenly stopped transmitting data.
