The Organic Geochemistry Unit (OGU) is based in the School of Chemistry of the University of Bristol. The research we conduct aims to develop our understanding of the biogeochemistry of modern-day and ancient environments and the way that it is affected by natural processes and the actions of mankind. This is achieved principally through the application of cutting-edge analytical chemistry and instrumental techniques.

Organic geochemistry is the study of the impacts and processes that organisms and once-living organisms have had on the Earth. Organic geochemistry includes studies of recent sediments to understand the carbon cycle, climate change and ocean processes. Studies of ancient sediments and rock help to understand the origins and sources of oil petroleum geochemistry and the biochemical antecedents of life.
