Birddog

This manual describes all aspects of a field seismic crew, on land, in terms of their relevance to the activities of the birddog, who is the company's representative on that field crew. In particular, it descibes the essential functions of the birddog which are data quality control (all forms) and testing to ensure optimum data quality. Some fundamental concepts of the seismic methods are described. Written in a way that is not specific to any particular equipment or technology, it concentrates on the principles and methods of supervision which are common to all procedures and equipment.
