Objectives At the completion of this subject students will have an overview of the physical features of aquatic systems; achieve an understanding of the chemical features of aquatic systems; gain an understanding of the fundamental physico-chemical processes operating in aquatic systems; be able to appreciate current pollution issues; review a range of commonly-used field and water quality monitoring techniques; develop a range of new analytical skills in the laboratory.
Synopsis This eight-point subject will be available in second semester and will give a basic understanding of the principles of water chemistry; experience with sampling and analysis of marine and freshwaters; and an introduction to the broader study of aquatic systems. Subject matter covered will include the hydrologic cycle; geomorphology and hydrodynamics of rivers, lakes and estuaries; light and thermal phenomena in aquatic systems; weathering of rocks and formation and nature of sediments; major ions in natural waters; dissolved gases; carbon dioxide equilibria and pH; nutrient cycles; redox equilibria; heavy metal complexation; dissolved organic carbon; sampling and analysis of natural waters. The practical subject will cover the major techniques used for water analysis and a field excursion.
