Description including Unit Aims
This unit will be presented in 20 lectures by lecturers from three Schools and will cover the major observational and analytical approaches used to trace earth and environmental processes, thereby underpinning our understanding of the Earth System. These include the use of isotopic and chemical tracers that track movement of energy and mass around the major reservoirs of the surface Earth (biosphere, lithosphere, geosphere) and the transformations of chemical state that govern the Earth’s environment. We will seek to understand the major controls on these tracers on the modern Earth with a view to using them to understand the past, particularly, but not limited to Pleistocene, Holocene and Anthropocene timescales. We will also discuss the major changes that the ocean-atmosphere-climate system has undergone over Earth history and the context that provides for understanding the modern climate system.
Intended Learning Outcomes
On successful completion of the unit you will be able to:
- outline the basic logic behind the use of a range of isotopic and chemical tracers of Earth System processes;
- quantitatively analyse data on a range of chemical and isotopic tracers, including mass balance calculations, simple box models etc;
- understand the application of these tracers to the study of the present and past Earth system;
- outline the basic strategies for the remote observation of the Earth and to choose between different methods for different applications;
- synthesise data from a range of scientific sources (especially journal articles) into a quantitative understanding and presentation of the operation of key tracers of the Earth system.

Assessment Information
This unit will be assessed through a combination of a 3-hour exam in January (90%) and through participation in literature based discussion sessions (10%). Assessment will be completed in accordance with the University Regulations and Code of Practice for Taught Programmes, available online at http://www.bristol.ac.uk/esu/assessment/codeonline.html
