Underwater acoustics is the study of sound propagation through water. As sound travels much more efficiently through water cetaceans have evolved to use this mechanism for navigating, finding food and communicating. This ability allows cetaceans to carry out their normal functions irrespective of sight which would be greatly influenced by turbidity, depth and darkness.

Module material placed on moodle to include:
All assessments are formative and summative, they contribute to the module grade. The module is 100% continuous assessment and there is no terminal examination. The module is assessed using a combinatino of theoretical and practical excercises including presentations, data analysis and reporting.
