On the impact of climate change on sonar performance
conference paper
Climate change has a substantial effect on the environment. Consequently, it will also impact sensors that are deployed in these changing environments. This paper investigates the impact of climate change on sonar performance, and aims to identify both direct and indirect relationships. Changes in oceanography, including layering of the water column and modifications of sound ducts, evidently influence the propagation of sound. Furthermore, climate change will change the soundscape, which comprises environmental noise generated by wind, rain, waves, sea ice, biological noise generated by marine mammals, and anthropogenic noise. The latter needs to be considered, as climate change will change human economic activities. Knowledge whether climate change impacts sonar performance in areas of interest to NATO is important for the planning and execution of anti-submarine warfare operations, and can be used as an indicator whether the environmental knowledge needs to be strengthened to realize an effective capability.
