A major Atlantic Ocean current system that regulates global climate has been slowing down for nearly 20 years. New research provides direct evidence of the decline across a wide area of the North Atlantic.
Scientists at the University of Miami Rosenstiel School of Marine, Atmospheric and Earth Science led the study. They analyzed data from four seafloor monitoring arrays stretching from the tropics to mid-latitudes. The instruments measured pressure, temperature, and currents to track deep ocean flows below 1,000 meters.
