Delia Wanda Oppo is an American scientist who works on paleoceanography where she focuses on past variations in water circulation and the subsequent impact on Earth's climate system.
[2] Following her Ph.D she started at Woods Hole Oceanographic Institution as a postdoctoral scientist working with William Curry.
[1] In 2014, Oppo was elected a fellow of the American Geophysical Union who cited her "for her contributions toward understanding the causes of Earth’s climate variability and its link to ocean circulation and the hydrological cycle".
[4] Oppo's research tracks past changes in ocean circulation, and the resulting impact of these changes on regional climate.
[10][11][12] Her research has revealed a weakening of the Gulf Stream,[13] which may impact weather patterns in the United States and Europe.
