13 December 2012Two Bristol biologists, Dr Rick Bruintjes and Irene Voellmy, have been awarded NERC internships through the Marine Renewable Energy scheme. Both will continue their investigations, started with Dr Steve Simpson (University of Exeter) and Dr Andy Radford (University of Bristol), into the potential impacts of anthropogenic noise.
Rick will be working in collaboration with HR Wallingford to improve an existing modelling tool which predicts movements of marine fishes in relation to anthropogenic noise sources. That model takes into account underwater acoustic propagation and hydrodynamics; Rick will add biological relevance in relation to the particular species being considered.
Irene will be working in collaboration with Ultra Electronics Sonar Systems to automate and simplify a military Passive Acoustic Monitoring system, originally invented for the detection of quiet submarines during WWII, to detect, classify and localise marine mammals by their emitted sounds. The system can then be used to assess changes in abundance in relation to anthropogenic noise sources.
