Event description

Description

Understanding past climates using oxygen isotopes from sediments

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 MBE

Prof Melanie Leng is Chief Scientist for Environmental Change Adaptation, the Director of the Centre for Environmental Geochemistry at the British Geological Survey, and Professor of Isotope Geosciences at the University of Nottingham. Her own lab group comprises the Stable Isotope Facility, which is part of the national centre of excellence for isotope research. She specialises in environmental studies including palaeolimnology and palaeoceanography. She was awarded an MBE in June 2019 for services to Environmental Research
