Description

This unit will cover the observational and analytical approaches used to trace the earth and environmental processes that underpin our understanding of the Earth System. Topics will 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.

Students will find the third year unit EASC30017 Oceanography of value. Students who have not taken EASC30017 will be expected to complete additional introductory reading.

Intended learning outcomes

On successful completion of the unit students will be able to:

  • outline the basic logic behind the use of a range of isotopic and chemical tracers of Earth System processes
  • understand the application of these tracers to the study of the present and past Earth system;
  • outline the basic strategies for direct and remote observations of the Earth and to choose between different methods for different applications
  • discuss climate forcing and mechanisms across a range of timescales;
  • understand the concept of climate sensitivity and how we estimate its magnitude from the geological record;
  • critically evaluate the evidence for a changing world presented in the Intergovernmental Panel on Climate Change (IPCC) reports, against a backdrop of palaeoclimate data
  • 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
