Basic Theory in Reflection Seismology

7.1.1 Dynamite Dynamite, a relatively uncontrolled impulsive energy source, was the first source used for seismic exploration [6]. When buried in a borehole dynamite provides an impulsive source with a wide bandwith.

Basic Theory in Reflection Seismology

The material in this volume provides the basic theory necessary to understand the principles behind imaging the subsurface of the Earth using reflection and refraction seismology. For reflection seismology, the end product is a "record section" from a collection of "wiggly traces" that are recorded in the field from which information about the properties of subsurface structure and rock can be derived. For the most part, the principles of imaging are the same regardless of the depth to the target; the same mathematical background is necessary for targeting a shallow water table as for investigating the base of the earth's continental "crust" at a depth of 30-50 km.

Exploration Seismology

This is the completely updated revision of the highly regarded book Exploration Seismology. Available now in one volume, this textbook provides a complete and systematic discussion of exploration seismology. The first part of the book looks at the history of exploration seismology and the theory - developed from the first principles of physics. All aspects of seismic acquisition are then described. The second part of the book goes on to discuss data-processing and interpretation. Applications of seismic exploration to groundwater, environmental and reservoir geophysics are also included. The book is designed to give a comprehensive up-to-date picture of the applications of seismology. Exploration Seismology's comprehensiveness makes it suitable as a text for undergraduate courses for geologists, geophysicists and engineers, as well as a guide and reference work for practising professionals.

K9 Explosive Detection

With oil comes oil exploration, with oil exploration comes seismic and with seismic comes commercial explosives. A lot of these technicians do a lot of flying throughout the western provinces going from oil site to oil site.

K9 Explosive Detection

Conduct efficient, effective and safe searches in any setting K9 Explosive Detection is for detector dog trainers and police departments looking for alternative training ideas or for ways to set up their own course training standards. Ron Mistafa examines some of the major training systems in use by police departments across North America, and he offers a system that combines the most effective elements of each one. This manual focuses on the how-to aspects of explosive detector dog (EDD) training. A gradual build-up of learning experiences and ongoing problem solving techniques produce more confident EDD teams. Ron also examines US and Canadian laws governing possession of explosive materials and devices, provides tips on working with other police specialty units, and explains how to involve non-police personnel at airports in EDD training.
