Dr. Bruce Armstrong has worked in underwater transducer design, acoustics, and system design for over 30 years. He received a B.E. in Engineering Physics from the University of Saskatchewan, and a M.Sc. and PhD. in plasmas physics from the University of British Columbia.
Dr. Armstrong worked for the Defence Research Establishment Atlantic from 1978 to 1985. As a member of the Transducer Group, he co-developed the transducer analysis finite element program MAVART, designed sound projectors and hydrophones for other Defence Scientists, and designed systems for ocean trials.
In 1985, Dr. Armstrong began work for what is now Ultra Electronics Maritime Systems Inc., where he developed two generations of directional hydrophones for DIFAR sonobuoys that continue to define the state of the art for flow and thermal noise, and bearing accuracy.
In 1994, Dr. Armstrong founded GeoSpectrum Technologies Inc., where he continues to use his experience in low-cost, high-volume transducers design to the benefit of customers in many countries.
Paul Yeatman has worked in transducer and acoustic system design for the past 16 years. Prior to that he worked with advanced materials and has experience with manufacture of a wide range of materials, including chemical compatibility and corrosion. Paul has a B. Eng. in Mechanical Engineering from Dalhousie University (then TUNS) and graduated with the Governor General’s Gold Medal for outstanding academic achievement.
Paul joined Hermes Electronics in January 1992, reporting to Dr. Armstrong. In 1994 he took over the transducer group when Dr. Armstrong left. In 1998 Paul joined Geco-Prakla and oversaw the productionisation of a new hydrophone design. He continued working for Geco on various aspects of seismic streamer development until he returned to Hermes, now Ultra Electronics, as the Manager of a new business unit called Naval Systems. Paul was in charge of a team of engineers developing towed arrays, towed active sources, moored systems, etc. In 2006 Paul joined GeoSpectrum as a partner.
Paul’s experience encompasses transducer design, but primarily his expertise is complementary to Dr. Armstrong’s as a systems design expert in the field of hydroacoustics, and with experience in assembling teams of people and companies well suited to solving systems problems.
Arnold Furlong has over 30 years experience in business operations, technology development, and sales in the ocean technology sector. He has a B. Eng. in Mechanical Engineering from Dalhousie University and a B.Sc. from Mount Allison University.
Arnold co-owned Brooke Ocean Technology with Geoff Lebans from 1990 until it was acquired by ODIM in 2006, and later by Rolls Royce. While at ODIM and Rolls-Royce he was the site manager and managed the sales and production of environmental sensing products. Under his leadership a product line was created that generated millions in annual sales. Arnold joined GeoSpectrum in 2013.
Arnold’s technical expertise is in the development and production of ocean instrumentation (non-acoustic), autonomous cable handling systems, towed systems and sensor platforms.
Geoff Lebans has 30 years experience in underwater equipment design, towed systems, sensor platforms, winches and handling systems for towed sensors, and off-board craft launch and recovery systems. He holds a B. Eng. in Mechanical Engineering from Dalhousie University, (then TUNS) and B.Sc. from Mount Allison University.
Geoff was co-owner of Brooke Ocean Technology from 1990 until acquired by ODIM in 2006. While at ODIM Brooke Ocean, Geoff and his partner Arnold Furlong commercialized a number of technologies and grew the company to a team of over 50 employees. After ODIM was acquired by Rolls-Royce and became part of their Naval group in 2010, Geoff joined the Advanced Programs group in conjunction with being the business development lead for the Canadian Naval operations in Dartmouth, Nova Scotia and Peterborough, Ontario. Geoff also acted as the subject matter expert for off-board craft and unmanned vehicle launch and recovery systems.
