K. Douglas Nelson Lecture Series, this week featuring Hope Jahren
The Department of Earth Sciences is pleased to announce a lecture by Hope Jahren, from the School of Ocean and Earth Science at the University of Hawai’i:
“The Effect of Elevated pCO2 on C3 Plants through Geologic Time,” Thursday, Oct. 24, at 4 p.m. in Heroy Geology Lab, room 113
Professor Jahren is an isotope detective. Her research focuses on living and fossil organisms and how they are chemically linked to the global environment. She uses measurements of the stable isotopes of carbon, nitrogen, hydrogen and oxygen in organic matter to elucidate information about metabolism and environment, both on human time scales and through geologic time. She is well known for her work on the chemistry of fossil wood, coaxing detailed climate information about precipitation, carbon dioxide, seasonality and humidity from the remains of trees that grew many tens of millions of years ago.
