Lamont-Doherty Earth Observatory

Gisela Winckler is a Lamont Research Professor at Columbia University’s Lamont-Doherty Earth Observatory where she also serves as the Associate Director of the Geochemistry Division. Winckler received her Ph.D. in Physics from the University of Heidelberg in 1998. She is a climate scientist and isotope geochemist interested in climate change and biogeochemical cycles. She uses elemental and isotopic analyses (noble gases, U-Th series, cosmogenic and radiogenic isotopes), to unravel processes of climate and environmental change in the oceans and on continents, on timescales ranging from decades to tens of millions of years. Her research uses climate archives such as deep-sea sediments, lake sediments and polar ice cores from Antarctica and Greenland. In 2019, she co-led IODP Expedition 383 (DYNAPACC – Dynamics of the Pacific Antarctic Circumpolar Current) on the Joides Resolution to the South Pacific to investigate Plio-Pleistocene atmosphere-ocean-cryosphere dynamics in the Pacific and their implications for regional and global climate and atmospheric CO2.
