Researchers at Georgia Tech analyzed the weakening of ocean currents and how it could affect ocean life. A report published by Science studied the reaction of ocean currents to climate change, resulting in a potential decline in biological activity and nutrients in the North Atlantic. Using empirical data led by Jean Lynch-Stieglitz, chair of the School of Earth and Atmospheric Sciences, the study observed the sediments at the Gulf Stream's origin. The region plays an important role in the North Atlantic's biological activity, particularly the ocean currents that could weaken due to greenhouse gas emissions and climate change.
