Calcareous Nannofossils and Paleogene Hyperthermal Events of the Salisbury Embayment
Jean Self-Trail
U.S. Geological Survey Reston, VA
Multiple extreme and rapid warming events, also called hyperthermals, occurred during the Late Paleocene and Early Eocene. Calcareous nannofossils (a type of marine algae), along with other microfossils, carbon isotopes, and lithology are used to document changes in ocean acidification and sedimentation during three of these events in the Salisbury Embayment. I will discuss ongoing research on the Pre-Onset Excursion (POE), the Paleocene Eocene Thermal Maximum (PETM) and present a “sneak peek” of preliminary research on the Eocene Thermal Maximum 3.
Non-Smithsonian visitors will be escorted to the Cooper Reading Room at 6:50 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitutional Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.
