TITLE Acoustic Remote Sensing and its Application in Marine Science

 
UM LEVEL 03 - Years 2, 3, 4 in Modular Undergraduate Course

 
MQF LEVEL 6

 
ECTS CREDITS 2

 
DEPARTMENT Physics

 
DESCRIPTION The study-unit provides an introduction to the basic concepts, instruments and operation of acoustic-based methodologies used in marine scientific research, and the processing and interpretation of the data they generate.

The structure of the study-unit involves:
1. Theory of underwater acoustics (basic principles of acoustics, sound propagation, interaction of sound with seafloor and water column)
2. Acoustic remote sensing instruments and their operation:
a. Single beam and multibeam echosounders;
b. Side scan sonars;
c. Seismic reflection profiling;
d. Acoustic Doppler Current Profiling;
e. Remotely Operated Vehicles and Autonomous Underwater Vehicles;
f. Underwater navigation and tracking.
g. Survey planning
3. Acoustic data processing, visualisation, integration and interpretation.
4. Advanced acoustic data analyses strategies.
5. Applications in marine science.

Study-unit Aims:

- To give a grounding in the basic principles and core concepts of seafloor surveying and exploration.
- To introduce a range of state-of-the-art geophysical, visual and seabed sampling instruments used in seafloor exploration.
- To introduce the skills required to acquire, process, manipulate, integrate, visualise and interpret seafloor data sets using commercial and open-source software.
- To demonstrate the wide range of industrial and academic applications of seafloor exploration, with a focus on marine geosciences.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be:
- able to explain the basic theory of acoustics and acoustic propagation;
- able to describe the acoustic measurement systems used for sensing the underwater environment;
- able to evaluate the role of acoustic measurement systems with respect to other types of measurements used underwater;
- familiar with the state-of-the-art instruments and techniques used in acoustic remote sensing and their applications in marine science.

2. Skills:

By the end of the study-unit the student will be able to:
- design an acoustic remote sensing survey and report results professionally
- acquire, integrate and interpret a range of acoustic remote sensing data types
- apply industry-standard software to process, visualise and analyse acoustic remote sensing data
- select and apply appropriate acoustic remote sensing data acquisition methodologies for marine scientific applications
