Bioacoustics (3 ECTS)

Semester: 1st

Code: 14331085

Coordinator: Sérgio Jesus (

The objective of this elective unit is to make the student aware of ocean sound of biological origin: sound sources, characteristcs, space-time distributon and sound propagation. Ocean sound imaging and usage for remote passive monitoring. Technicques for measuring and analysing sound.

By the end of this UC, students should acquire the theoretical knowledge above described, as well as the practical knowledge on the identification of the most common species of cetaceans occurring in Portugal and the application of photo-identification techniques. Additionally, students are expected to assess climate conditions for cetacean sightings and also potential constraints related to this type of field work.

15 h of lectures + 12 h of field work + 4 h of labs + 53 h of independent work.

The student will use the time assigned as "independent work" to study for a written exam.


As the registration for any elective is mandatory, please wait for an email by the MSc Coordinating Team requesting the names of the electives that you plan to choose for your 2nd year, 1st semester.


A series of descriptive lectures with the support of reference textbooks, images, movies and sound tracks of a variety of animals from various areas and various underwater choruses. The experimental component is restricted to the role of equipment user and applicatons for underwater sound analysis both in tank and at Ria Formosa lagoon. Grading will use both individual work performed during the semester and the result of the final exam.
