Education and career
An interest in the natural world, combined with the logic of science and math, attracted Lynch-Stieglitz to science and after a summer at the Duke University Marine Laboratory she decided on a career in physical oceanography.[1] In 1986, she earned B.S. degrees in physics and geology from Duke University[2] and for two years she worked as an oceanographer at the Pacific Marine Environmental Laboratory. From 1988 until 1989 she worked at the Maryland Science Center and as a programmer at Johns Hopkins University before moving to Columbia University where she earned an M.A. (1991) and Ph.D. (1995) in geological sciences.[3] After two years as a postdoctoral scholar at Woods Hole Oceanographic Institution, in 1996 she returned to New York where she joined the faculty of the Lamont–Doherty Earth Observatory. In 2004, Lynch-Stieglitz moved to the Georgia Institute of Technology where she was promoted to professor in 2010.[3]
From 2012 to 2015, Lynch-Stieglitz was the Editor of Earth and Planetary Science Letters.[4]
In 2015, Lynch-Stieglitz was elected a fellow of the American Association for the Advancement of Science "for bringing physical oceanography approaches to the study of transient circulation changes during ice ages, providing a window into the ocean’s interaction with today’s climate change."[5]
Research
Lynch-Stieglitz's research links the ocean and climate over the past 100,000 years. She has used carbon isotopes in benthic foraminifera to reconstruct air-sea exchange in carbon isotopes,[6] changes in the movement of deep water masses,[7] and Antarctic Intermediate Water in the transitions between glacial and interglacial periods.[8] In the Atlantic Ocean, she has examined movement of the Gulf Stream during the Last Glacial Maximum[9] and linked changes in the Atlantic meridional overturning circulation and to rapid changes in climate.[10][11][12] Her research also extends to regions where ice alters the exchange of carbon dioxide between atmosphere and ocean in glacial periods,[13] and work in the Pacific Ocean where she has examined sea surface temperatures from the Last Glacial Maximum to the present.[14]
