Noise logger overview

Summary

In our attempt to monitor the presence of marine mammals, especially cetaceans, their acoustic activity opens the opportunity for us to eavesdrop and to study their behaviour passively through listening and detecting their sounds and vocalisations. This overview of underwater sound recording systems which can be used to study the life of the mainly cryptic marine mammal species is intended to facilitate researchers, potential funding bodies and finally regulators with information on the potential of this technique, its limitations and most importantly with technical details and a market overview.
