Ted has over 37 years of experience in geophysics, during which time he has been
involved in field surveys/operations/management, data quality , safety, data
enhancement, compilation and interpretation for various projects throughout the world.
Ted was an owner and president of High-Sense Geophysics Ltd. (the third largest
geophysical airborne survey company in the world until it was sold to Fugro N.V at
the beginning of 2000) and one of three partners in the geophysical consulting company
Urquhart Dvorak Limited. He is now the owner of New-Sense Geophysics Limited conducting
airborne geophysical surveys world wide.
He has participated in projects as diverse as oil basin
studies, mineral and diamond exploration and radioactive satellite fragment recovery
and was actively involved in the development of several EM systems (HeliTEM, Quantem
and AFEM). Academically, Ted has conducted research into the correlation of magnetic
anomalies with geological factors on both a large and small scale. Several of his
publications are frequently quoted in the scientific literature. Ted consults with
clients, manages projects, provides quality control services, processes and interprets
EM, magnetic and radiometric data, and trains foreign geotechnical personnel.
He is actively involved in the geoscientific community and was a director and past
VP of the Prospectors and Developers Association of Canada. Ted also developed many
of the processing and interpretation strategies in common use today including
filtering, inversion and anomaly enhancement routines. Under his management and
guidance these ideas formed the core of the software package of Geopak Systems, a
division of UDL.
Currently Ted is a Director of CHAPLEAU RESOURCES LTD., SILVER SPRUCE RESOURCES INC. and SHOULDICE HOSPITAL LIMITED as well as the Vise President of South American exploration for Global Gold Corp. and President of GeoExplo Limitada and New-Sense Geophysics Limited.
Owner and President, GeoExplo Ltda. (2002 - present)
Purchased High-Sense Geophysica Limitada from Fugro Airborne Surveys and changed the name to GeoExplo Ltda. The original company provided only airborne geophysical surveys. The company now specializes in all aspects of airborne geophysical surveys including project management, quality control, safety, interpretation and processing.Regional Manager (South America), Fugro Airborne surveys (2000-Dec 2001)
After selling High-Sense Geophysics to Fugro NV. at the beginning of 2000 Ted moved to Santiago, Chile to reorganize and set up new offices and operations in South America for Fugro Airborne Surveys in Rio, Lima and Santiago. Duties included overall management of operations, quality control and safety.Owner and President, High-Sense Geophysics Limited (1993-2000)
Formed High-Sense Geophysics Limited, which quickly grew to become the third largest geophysical survey company in the world based on a reputation of quality and safety. As president Ted managed the company and its operations. As chief quality control officer Ted maintained a special interest in the quality of the operations and data as well as developed systems for maintaining quality and safety.Urquhart Dvorak Limited (UDL) and Geopak Systems (1984 -1993)
Formed Urquhart Dvorak Limited as well as directed the development of Geopak Systems as a software division. Ted performed processing and interpretation of both ground and airborne electromagnetic, magnetic and radiometric data as well as survey planning, quality control, management and supervision for clients. UDL/Geopak under Ted's direction and supervision also developed software and unique processing procedures as well as training of foreign nationals.Consulting Geophysicist W.E.S. Urquhart Associates Limited (1980-1984)
Formed W.E.S.Urquhart Associates Limited and development several software packages including contouring, filtering, and inversion. Specialized in interpretation of EM and magnetic data and computer hardware and software installations. Performed detailed theoretical and practical study of pole/equator reduction of magnetic data. Ted was part of the NASA Magsat team responsible for the reduction, analysis and utilization of magnetic information collected by satellite and received the NASA Group Achievement Award for his work with NASA.Project Geophysicist (1980)
Questor Surveys Limited, Toronto, Canada -- Interpretation of electromagnetic and magnetic airborne surveys for diamond exploration in West Africa and the James Bay Lowlands.Project Geophysicist (1976-1979)
Northway Survey Corporation, Toronto, Canada -- Duties included field geophysicist and project manager responsible for field operations, quality control and safety. Ted interpreted aeromagnetic and spectrometric data for the countries of Lesotho, Venezuela, Brazil and Upper Volta. Targets included base and precious metals, diamond and oil exploration and regional evaluations. Field geophysicist in charge of the interpretation of airborne spectrometric data for the Soviet COSMOS 914 fragment recovery project.Project Geophysicist (1970-1976)
Summer projects for Imperial Oil Limited and University of Toronto -- Worked on various projects involving geological and geophysical mapping.PUBLICATIONS: (Sample only)
