Dear All,
Our Smith Lecture speaker this week is Aradhna Tripati, UCLA. She is speaking on Glacial Climate from Clumped Isotope Thermometry. Abstract below.
Smith Lectures are Friday afternoons from 4:00 to 5:00 pm, in Room 1528 C.C. Little Building. A reception is held following the lecture in 2540 C.C. Little. The events are free and open to the public. A full schedule for the term may be found on our website:

This is the final Smith Lecture for Winter term 2014. The Department wishes everyone a pleasant summer, and we look forward to seeing you again on September 12 when the Fall term Smith Lecture series begins.
Best regards, -Anne

Abstract:
A primary goal of paleoclimate research over several decades has been to establish the magnitude of temperature change in different regions since the Last Glacial Maximum (~23-19 thousand years ago). Data on past climates have been used to study climate processes, evaluate the accuracy of model simulations, and assess climate sensitivity to greenhouse gas forcing. During this seminar, I will present what we have been learning about glacial paleoclimate from the application of carbonate “clumped” isotope thermometry. This proxy is based on the measurement of multiply substituted isotopic variants of molecules (isotopologues). I will describe results from modern samples and glacial samples, including from the Western Tropical Pacific.
