644929 external_news 1614786074 1614802444 Georgia Tech College of Sciences Dean Susan Lozier is quoted, and her research cited, in a New York Times story detailing scientists' concerns about the northern arm of the Gulf Stream, the river-within-an-ocean that transports warmth to the North Atlantic. Several studies now suggest this northern portion of the Stream and the deep ocean currents it’s connected to may be slowing, resulting in a "cold blob" of water just south of Greenland that could result in negative consequences for continents along the Atlantic.  Lozier, the John Clark Sutherland and Betsy Middleton Chair, is a physical oceanographer who is also the president of the American Geophysical Union. She is the international project lead investigator for Osnap, an array of ocean sensors stretching from Canada to Greenland and Scotland. “There are very strong signals in the ocean of climate change,” Lozier says in the story. But most studies on the AMOC (Atlantic meridional overturning circulation) don’t measure the “conveyor belt” directly.
