Summary of Expertise:

Listed with other top experts in: 

GEOPHYSICS; MINERAL RESOURCE EXPLORATION. Expert has extensive experience in the use of geophysical techniques for solving geological and engineering problems. His primary skill lies in the application of non-seismic geophysical methods for environmental, groundwater and geotechnical investigations. He has also been involved in the use of geophysical techniques for exploration of metallic minerals, industrial minerals, oil, and natural gas. This work has taken him to four continents.

GEODESY (GRAVITY MEASUREMENTS). A significant part of Expert's career has been spent in measuring the earth's gravitational field. Much of this work has been directed to the delineation of bedrock valleys in water resource investigations. He has made numerous measurements of the gravity field to calibrate pressure measuring devices.

MAGNETICS. Expert has conducted numerous magnetic surveys. He has used magnetics extensively to locate metallic debris in environmental projects. In the area of mineral resource investigations, he has supervised numerous magnetic surveys to determine the distribution of magnetic material in the earth's upper crust.

ELECTROMAGNETICS. Expert has used electromagnetic measurements to determine the distribution of geological units within the earth's near surface. A significant part of his work is the delineation of leachate plumes in environmental studies. He has also used electromagnetics to determine the distribution of conductive minerals in mineral resource exploration.

GEOPHYSICAL ELECTRICAL METHODS. Expert has used electrical surveys (resistivity, induced polarization, and spontaneous potential) to delineate geological units. A major part of this work has been documenting the distribution of leachate plumes, both vertical and horizontal. He has conducted resistivity surveys for designing electrical grounding systems.
