Ocean monitoring plays a vital role in both fisheries and aquaculture sector. There is a need to measure various parameters in different locations at a regular interval of time. In-situ devices come into play and data communication and transfer of data is important. Monitoring devices for underwater studies can send/receive data either via acoustic or electromagnetic (EM) wave propagation.
