I received my B.Sc. degree in physics from the University of Victoria, Canada in 1982, my M.Sc. degree in physics from the University of Victoria, Canada in 1985. At that point, I took a period of time off studies and worked as an Experimental Scientist at the CSIRO Marine Laboratories in Hobart, Tasmania. At CSIRO, I configured and developed the data acquisition system for one of the early RD Instruments, Acoustic Doppler Current Profilers on the RV Franklin. I returned to Canada in 1987 and began work on my Ph.D. at the University of British Columbia Oceanography Department. Working with the IOS Ocean Acoustics group my thesis research involved the use of acoustics to study near surface ocean processes. After graduating in 1991, I took up a position as a Research Associate with Dr. Alex Hay at Memorial University of Newfoundland (MUN), in St. John's, NF studying sediment transport processes using acoustic systems. I accepted a post of Assistant Professor in the Dept of Physics and Physical Oceanography at MUN in 1996.
Self-contained scientific echo sounder system.
Research activities involve the exploration of oceanographic processes through the use of acoustic systems. The revolution in electronics and computing capabilities provide many opportunities for instrument development in oceanography. Current interests include; the processes responsible for ambient sound in the ocean, the use of coherent Doppler sonar for high resolution water velocity profiling, the suspension of sediment in the nearshore zone, and the application of acoustic systems to fisheries acoustics. I believe that it is fundamental that any instrument development be motivated by scientific need and not simply by technological capability.
