Introduction to the Dura Spark Sound Source
The Dura-Spark has been designed to provide a stable, repeatable sound source for
sub-bottom geophysical surveys. The long life, durable electrodes produce a
consistent pulse signature and keep operational maintenance to a minimum. This
provides increased survey efficiency and equipment reliability as the sparker tips
rarely need replacement.
The Dura-Spark L80 is based on the CAT100 catamaran, providing a stable platform
whilst under tow. The Dura-Spark L80 consists of 2 arrays of 40 tips forming a single
array of 80 tips, providing a powerful high resolution sound source.
The typical operational bandwidth of the Dura-Spark L80 is 500Hz to 5KHz. When
coupled with the CSP-Nv Seismic Power Supply the system offers 2000J/s peak
discharge rate, as well as industry leading design and safety standards.
