Comparative bioacoustics II: Marine Mammals (3 ECTS)

​

Aims: In this module we will review the production/perception, nature, function of acoustic signals in marine mammals (pinnipeds and cetaceans) as well as the impact of noise. We will describe the different types of acoustic signals produced by pinnipeds, odontocetes and Mysticetes, and the anatomical basis of their production. We will see their hearing abilities, and review the impact of noise on their general behaviour and vocal production. We will also present technologies used to study marine mammal vocal behaviour, from passive to active monitoring and the analysis methods linked to these monitoring methods (PAM and tags). During the practical sessions, we will use sound analysis software such as Seewave, Avisoft and Raven. 

 

​

Research talks on pinniped and cetacean acoustic communication networks and noise

impact will expose you directly to current research.

 

Learning outcomes

 

By the end of the module, a successful student should be able to:

1. Demonstrate an understanding of how acoustic signals of marine mammals are produced, structured and perceived;

2. Demonstrate an understanding of noise impact on marine mammals

3. Demonstrate a good understanding of tools for analysing marine mammal vocalisations

4. Demonstrate a good understanding of scientific devices that can be used to study marine mammal behaviour (PAM and tags).

​

Assessment

​

The final mark will be based on the oral presentation of a scientific paper (duration = 10 min + 5 min questions).
