Ecosystem monitoring

Revealing the secrets of the deep Acoustic sensing enables non-invasive learning about the aquatic ecosystem. Active acoustics have been used by academia and governmental institutions for decades to quantify fish stocks in order to manage the populations. Recently the management focus has shifted from individual fish stocks towards a more holistic ecosystem approach, looking at the whole food web from small plankton to large mammals.

Ecosystem monitoring

Through the extensive range of Simrad scientific echo sounders, multibeams and sonars, Kongsberg Maritime is well positioned to give the users the very best overview of what happens below the surface. From layers of zooplankton drifting around the oceans, fish feeding on the plankton and predator prey interactions between fish and mammal, acoustics will reveal it all without disturbing the actual interactions. All systems are calibrated in order to output absolute values of the biomass observed, and all data is stored in a well documented RAW data format that has been scrutinised by scientists worldwide.
