Understanding past climates using oxygen isotopes from sediments – 2019 Rick Battarbee Lecture

Professor Melanie Leng will be giving the 2019 Rick Battarbee Lecture at UCL Geography on 30thMay 2019. Melanie is one of the world’s leading isotope geochemists, and many members of the department have sustained collaborations with her over the past 20 years.

Tickets are free, but please register here in advance. Usual wine and nibbles to follow after the lecture.


Talk Abstract

The isotope composition of endogenic and biogenic carbonates and diatom silica are commonly used as palaeoclimate proxies from lake and ocean sediments. This talk reviews the controls on the isotope composition of lacustrine skeletal and non skeletal deposits and illustrates how stable isotope studies contribute to an understanding of environmental and climate change. There are differences in the palaeoclimate potential of different types of sediments which will be investigated. A number of recent case studies will be presented from across the globe.

Professor Melanie Leng Biography
