BIOCOM'19 sea trial (January 14-18, 2019)

A joint IEAPM - UALG experiment took place in the bay of the I. of Cabo Frio, Arraial do Cabo (RJ,Brasil). The objective of the experiment was to gather data to support the research being carried out in the IEAPM lead Biocom project, namely, acoustic communications transmissions, soundscape and particle motion data, to characterize the biological ecosystem off the Cabo Frio Island. The correlation biological activity with the upwelling regime is of particular interest.

The acoustic sound source used in the BIOCOM'19 experiment, transmitting environment probes and communication signals, acrosso the Cabo Frio bay.
Two bottom installed tripods: one with 4 hydrophones cabled to shore and recording since 2018, the other with a SiPLAB (University of Algarve) custom built acoustic vector sensor with a single hydrophone and two tri-axial accelerometers in a single mould (vertical white container) and its battery pack (horizontal container).
