The Biosphere in the Earth System

Year Three, Semester Two Course Code: GY3354

This module will provide you with an advanced-level understanding of contemporary biosphere processes, with an emphasis on the carbon cycle. We will consider the broad drivers of the biosphere and the feedbacks between the biosphere and the wider climate system. The module will consider in detail photosynthesis in relation to the global carbon cycle. You will then learn about the different feedbacks in various biomes and current research into the relationships between Climate and the Carbon Cycle. The importance for future climate change will be addressed. The module introduces stable isotope theory and focuses on applications to explore carbon exchange processes. In practical sessions, you will use state of the art instrumentation to measure and analyse a range of plant physiological data. The results will be presented in the form of a scientific paper.

Assessment will by:

• A written report (ca 2500 words) as an article for Biogeosciences. Students can choose which practical they would like to use for their report (Photosynthesis & Farquhar model or tree ring isotopes) offered.
• 50% by written examination.
