Listening Underwater

2pm

Listening Lab

Underwater there is usually no silence. It’s true that many sounds can be almost unnoticeable, but there are species that produce sounds that can dominate the acoustic landscape of a location. We are not just talking about whales and dolphins, many fish and invertebrates produce sounds to communicate with each other. On the other hand, anthropogenic noise now occurs in almost all marine ecosystems. While it is easy to realise the effects of noise in the air, it is usually not very clear to us what impact the noise we generate can have on aquatic animals. In this activity we will realise what can be heard underwater with several examples that can be found in Portuguese waters.

Activity promoted by Fish Bioacoustics Lab (MARE and CE3C – FCUL).
