Applied Acoustics Dura-Spark UHD and UHD 400+400

Description

The Dura-Spark UHD 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 single deck Dura-Spark consists of 3 or 5 arrays of 80 tips allowing the operator to tune the source from the vessel to their application. This flexibility together with selectable source depth allows the source to be used in both shallow and deep waters. The typical operational bandwidth of the Dura-Spark UHD  is 300Hz to 1.2kHz. 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.

Newly introduced the Dura-Spark UHD 400+400 consists of 2 decks of 400 tips that allow the operator to tune the source from the vessel to its application. Each deck can be fired independently by its seismic power supply, in flip flop mode, combined with fire delays or a split fire delay. Utilising the fire delay functionality the signatures from the 2 decks can be combined to bubble form the sound source signature. This flexibility, together with selectable source depth, allows the sound source to be used  for multiple seismic data gathering applications.

The typical operational bandwidth of the Dura-Spark UHD 400+400 is 300Hz to 1.2kHz. When coupled with the CSP-SNv Seismic Power Supply the system offers 4000J/s peak discharge rate, as well as industry leading design and safety standards.
