Upcoming BIOCOM'19 experiment in Cabo Frio - Brazil

BIOCOM'19 - Bio Communications sea trial

This IEAPM - UALG joint experiment will place in the bay of the I. of Cabo Frio, Arraial do Cabo (RJ,Brasil) from 9 to 16th January, 2019. The objective of the experiment is 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.

People involved from UALG: S.M. Jesus.
