The Effects of Noise on Aquatic Life II: Advances in Experimental Medicine and Biology

Costa, D., Schwarz, L., Robinson, P., Schick, R. et al.

Using long-term empirical data, we developed a complete population consequences of acoustic disturbance (PCAD) model and application for northern elephant seals. We assumed that the animals...

2014
Open Access Journal Article

Marine Pollution Bulletin

Merchant, Nathan D., Pirotta Enrico, Barton Tim R., and Thompson Paul M.

The potential impacts of underwater noise on marine mammals are widely recognised, but uncertainty over variability in baseline noise levels often constrains efforts to manage these...
