Bioacoustics experiment

Bioacoustics experiment in Ria Formosa

mussels sound tripod in Ria Formosa

In the framework on the course of Bioacoustics (Master of Marine Biology) students have deployed an acoustic recording device and a CTD over a 24 hours period, near a bivalve aquaculture farm in Ria Formosa Natural Park, near Faro beach. Both tidal related mussel generated sound and anthropogenic noise of passing by boats was recorded together with dissolved O2 and other environmental parameters. People involved from CINTAL/SiPLAB: S.M. Jesus and R. Duarte and the Bioacoustics students.[more...].
