Gisela Winckler

Gisela Winckler is a Professor of Climate at Columbia University's Lamont-Doherty Earth Observatory. She specializes in geochemistry and paleoclimatology, focusing on climate archives like deep-sea sediments and ice cores to study Earth's climate history over millions of years. Her research employs isotopic analyses (e.g., noble gases, U-Th series) to understand processes driving natural and anthropogenic climate change.

Education: Ph.D. and M.Sc. in Physics from the University of Heidelberg. Active in interdisciplinary projects such as IODP Expedition 383 and GEOTRACES cruises. Key focuses include Antarctic ice sheet dynamics, Southern Ocean circulation, and dust-climate interactions. Collaborates widely on machine learning applications for ice core records and cosmogenic nuclide dating.

Her recent work emphasizes millennial-scale climate transitions, glacial-interglacial variability, and the role of ocean currents in global carbon cycles. Articles highlight advancements in understanding West Antarctic Ice Sheet behavior, Pacific Antarctic Circumpolar Current dynamics, and hydrothermal iron fluxes.
