Learning Outcomes

Having successfully completed this module you will be able to:

• Outline the fundamental principles that underpin stable and radiogenic isotopes systems.
• Discuss how geochemistry can help solve geological, environmental and oceanographic problems.
• Describe common geochemical reactions in the Earth and Ocean System and interpret complex geochemical datasets.
• Analyse, explain and interpret a variety of geochemical data sets
• Compare and contrast the distribution of chemical elements in water, soils, and rocks.
• Explain how different elements cycle through the earth-ocean system in past, present and future environments.

This module will introduce the fundamental chemical processes that operate within the Earth and Ocean system. You will learn about the origin, distribution and abundance of chemical elements in the Earth and Ocean. Via lectures, in-class exercises and practicals, we will introduce fundamental geochemical principles and explain how elements cycle through the Earth and Ocean. Practicals will be delivered within the Centre for Earth Research and Analysis Southampton (CERAS), a world-class facility for the chemical and isotopic analysis of natural and anthropogenic materials. We will introduce different isotope systems (including radiogenic and stable isotopes) and relate these to exciting real-world practical examples. By the end of this module, you will have developed a holistic and quantitative understanding of geochemical cycles in the Earth and Ocean system and how these interact in a diverse range of past, present and future environments. The following material will be discussed within SOES2018: 1.Key Geochemical Principles 2. Distribution of elements in the Earth and Ocean system 3. Earths formation and its geochemical evolution 4. Earths carbon cycle and climate regulation 5. Isotopes and ocean circulation 6. Ocean acidification and carbonate chemistry 7. Geochemical tools and reconstructing past environments 8. Environmental geochemistry and the Anthropocene

Lectures: ~27 x 40 minute lectures will discuss key geochemical principles and how they relate to ocean, earth and environmental scientists. Lectures will be delivered using PowerPoint with material uploaded to Blackboard and Panopto. Where relevant, lecturer's own research experience is brought into the lecture sessions. References to relevant journal articles are provided as pre-session reading. Interactive learning sessions: In-class exercises during which students work alone or in small groups to re-inforce learning. Students will use using theoretical knowledge from lectures to make quantitative geochemical predictions, solve research questions, and analyse research papers. Practical laboratory sessions: Three laboratory sessions will allow students to consolidate knowledge from lecture material and apply their knowledge to real world case studies. Sessions will explore: (i) ocean acidification and the carbonate system, (ii) organic geochemistry and past environments, and (iii) isotope provenance and radiometric dating. In laboratory practicals, staff and postgraduate demonstrators provide support A wide range of support can be provided for those students who have further or specific learning and teaching needs.
