Passive Acoustic Monitoring 

Decimus and our Data Acquisition Card have been designed with the customer in mind. Our products minimise the risks associated with time and location delays by returning data to you on a daily or more frequent, if desired basis, giving confidence that project timelines can be met.

Conventionally, surveys for marine mammals have used visual techniques to search for animals at the water surface. However, sighting efficiency can be severely affected by weather conditions; it rapidly decreases in rough seas, is curtailed by factors such as fog and it cannot be used during the hours of darkness.
