Professor Victor Humphrey
His interests include numerical modelling of transducers and fields; parametric arrays and their applications in the laboratory and at sea; techniques of measuring the acoustic properties of materials; acoustic scattering from structures; nonlinear propagation in tissues and its use to improve imaging in medical ultrasonics.
Victor has a keen interest in applied acoustics and the potential for cross fertilisation of ideas between different fields of acoustics. He has a wide experience of conveying acoustic concepts to students from a broad range of backgrounds.
Dr Paul Lepper
Paul’s research topics include measurement and characterisation of underwater noise sources and the assessment of noise impact on marine fauna. These topics have included work to assess the construction noise from several offshore windfarm developments. They also involve investigation of various petroleum platforms and include projects looking at noise from small leisure craft.
Source characterisation, sound field modelling and modelling marine species exposure are treated by Paul. He is also involved in projects to assess hearing abilities of marine mammals and the use of acoustic deterrents. Furthermore, he is involved in the development of various systems for long term noise field assessment and passive detection of marine species and the use of various propagation models for sound field assessment.
Dr Peter Dobbins
Peter left Bath and went to SEA, Bristol, in 2005 where he worked partly on research projects related to marine mammals and novel waveforms, but mainly on product development programmes. Peter moved to Ultra Electronics, Weymouth, in 2010, where he has continued his interests in marine mammal monitoring, expanding the range of applications into the renewable energy field and covering active as well as passive systems. He has also been working on a range of conventional sonars.
Dr Philippe Blondel
Experiments are performed in the large tank facilities of the laboratory, in short sea trials, and in long deep-sea marine expeditions. Theoretical developments currently focus on models of high-frequency bistatic scattering (above 100 kHz) and monostatic backscattering (1 kHz to 500 kHz). The applications are varied and include: seabed mapping, tsunami studies habitat mapping (deep-sea coral reefs, Arctic ecosystems, continental margins), mine counter-measures (MCM), seafloor characterisation (TexAn software) and 3-D imaging of toxic waste in/on the seabed.
Dr Paul Fernandes
Paul’s work involves fisheries acoustics, including the use of echosounders and other sonar equipment for studying marine life and measuring fish stock densities. For active SONAR acoustic instruments, Paul is particularly interested in methods for identifying objects which scatter sound of multiple frequencies according to their physical, physiological and behavioural characteristics. He is involved in the development of scattering models, and validating these with empirical data.
Paul is Chair of various groups of the International Council for the Exploration of the Sea where his interests are centred around the development of active acoustics and the introduction of new technologies to study the abundance and distribution of fish.
He has been a key developer of acoustic techniques deployed in Antarctic waters using the AUTOSUB vehicle (NOCS, Southampton), for obtaining biomass estimations under ice.
