Abstract
As acoustic pollution in the oceans is increasing, it is becoming more important
to monitor it, with special attention on its effects on the behaviour of cetaceans.
In the near future governments may require constant monitoring during sea
construction projects or operations. One major construction activity in the coming
years will be the construction of wind farms. Not only will these farms produce a
constant low level noise in their direct environment while operating, but the building
of the foundations necessary to support the wind mills will produce impulsive
noise dangerous to any cetaceans in the area and lethal to, for example, fish larvae.
For these reasons, noise monitoring has become one of the objectives of the
European Seafloor Observation Network (ESONET), to investigate the level of noise
produced around European coastlines and its impact on the environment and cetaceans
especially.
Presented is the architecture for noise and marine mammal monitoring as it is currently
implemented in ESONET through the LIDO (Listening to the Deep Ocean Environment)
project. LIDO will detect in real-time changes in the background noise
levels and register acoustic events (natural, biological and anthropogenic), and
identify and track the sources when possible. As the system will be implemented in
varying environments, a modular design is used that can be adapted easily, based
on local requirements. While the system will most often run from a shore station, a
more limited version is developed that can run autonomously with minimal power
requirements.
