SOES6015 Introduction to Chemical Oceanography
The module is designed for graduates in any science discipline embarking on postgraduate studies in Ocean and Earth Science.
Aims and Objectives
• To introduce the basic concepts used in chemical oceanography. • To provide a basic knowledge of chemical processes in the ocean. • To provide a frame work to undertake more advanced courses within OES. • To introduce some of the techniques and practical skills needed when undertaking oceanographic chemical sampling and analyses.
Having successfully completed this module you will be able to:
- Able to convert between the different units used in chemical oceanography.
- Able to describe the distribution of the major sediment types in the ocean basins and the chemical controls that result in the observed distributions.
- Aware of the behaviour and importance of trace metals dissolved in seawater.
- Aware of some of the different chemical tracers used in oceanography.
- Able to interpret an estuarine nutrient data set.
- Ability to access chemical oceanography literature
- Data handling and interpretation skills
- Chemical oceanographic sampling techniques
- Chemical laboratory techniques and safety
- Familiar with the hydrological cycle and erosion processes.
- Aware of the differences between river water and seawater and the reasons for the differences.
- Able to discuss the impact of mid ocean ridge hydrothermal activity on ocean chemistry.
- Familiar with conservative and non conservative elements and their behaviour in the oceans using examples including nutrients, major and minor element, and trace metals.
- Aware of the biogeochemical cycles of the major nutrients within the oceans.
- Able to construct two box models.
- Aware of the behaviour of elements within estuaries.
- Familiar with the behaviour of dissolved gases in the ocean and their impact on ocean anoxia and carbonate chemistry.
The format of the module is lecture based. Calculations and simple exercises will be set throughout the course to allow students to employ the skills learnt in a practical sense that is relevant to their discipline. Chemical oceanography covers many facets of marine environmental science and a multitude of different spatial and temporal scales. Topics covered in this module span from evolution of the ocean to controls on chemical speciation in sea water and molecular diffusion processes. Chemical processes are essential in biological systems, they control the geology of the planet and they are key tracers utilised in understanding the physics of the ocean.
Restricted to MSc/MRes students within Ocean and Earth Science
Learning and Teaching
Teaching and learning methods
Formal Lectures: Will provide an introduction to the theory underlying chemical processes in the marine environment. Each lecture systematically covers the main concepts and topics by the use of PowerPoint presentations, supported by illustrated handout materials. The lecturers’ own experience in this field is incorporated where possible. Appropriate references to parts of course textbooks and introductory journal references are provided at each lecture. Problem Sheets: Numerical problems and answers are available each week to allow individual study to reinforce the concepts taught in the lectures. Online test: A test with multiple choice and single word answer questions will be available on www.blackboard.soton.ac.uk to give you feedback on your knowledge and understanding of the first half of the course. A wide range of support can be provided for those students who have further or specific learning and teaching needs.
