Learning Outcomes
- To analyse and interpret acoustic data sets, notably echo-sounder, side scan sonar and sub-bottom profiler data.
- To appreciate the potential pitfalls in positional data in terms of geodetic datums, and understand the basic principles of geodesy as they influence the apparent position of any acquired scientific field data.
- To demonstrate an ability to use computer packages for image analysis of spatial (remote sensing) data
- To understand and appreciate practical applications of marine acoustics.
- To understand how GPS, DGPS and RTK GPS works and be able to decide upon the most appropriate position fixing systems for a given application (to appreciate their accuracy limits, practical limitations and pitfalls in their use).
- To understand the behaviour of EM radiation and its utility in remote sensing systems
- To understand the fundamentals of acoustic propagation in ocean waters and near surface sediments.
