Sidney R. Hemming
Sidney R Hemming is a Professor in the Department of Earth and Environmental Sciences at Columbia University and a member of the senior staff at Lamont-Doherty Earth Observatory. She was trained as a geologist and isotope geochemist at Stony Brook University where she studied tectonics and sedimentation of the Paleoproterozoic Animikie Basin for her Ph.D., and she used similar analytical approaches to study the provenance of North Atlantic “Heinrich” layers as a post doc at Lamont. Since joining Columbia she has established Lamont’s AGES (Argon Geochronology for the Earth Sciences) lab. Her current research interests are geochronology, paleoceanography and paleoclimate. Her research themes include understanding provenance and processes in marine sediments, with specific emphasis on the archives collected from IODP Expeditions 361 (Agulhas Current System), 382 (Iceberg Alley, Antarctica) and 395 (Reykjanes Ridge).
