SIG Boomer on Yangtze River

SIG France has announced the delivery of a new SIG Pulse S1 boomer system to the Changjiang Institute of Survey Planning Design and Research (CISPDR). CISPDR is a state-owned enterprise subordinated to the Changjiang Water Resources Commission of the Chinese Ministry of Water Resources. It has been involved in two important hydraulic projects: the Three Gorges project and the South-to-North Water Diversion project. The commissioning has just been performed on the Yangtze River, in Wuhan. The geophysical team of CISPDR has been trained by Kim Ola of Meridata, Finland. The SIG Pulse S1 is a small 300-joules energy source, which can... (read more)

Sparker/Boomer in Baltic Sea

The University of Klaipeda, Lithuania, has taken delivery of a new SIG sparker system from SIG France. The sparker/boomer is a multi-channel seismic system suitable for working in shallow water conditions (water column of 100m) in the Baltic Sea. The energy source has a maximal output of 1,000 joules with the sparker, and 500 joules with the boomer sound source. The sparker works well in the low salinity (7g/l) of the Baltic Sea. Onboard training has been conducted by SIG France, Geomatrix UK, and system integrator and manufacturer of custom solutions Emma Technologies. Emma Technologies has manufactured the oceanographic winch... (read more)

SIG Pulse M2 Sparker/Boomer System for Chinese University

China Eastern Normal University has purchased the SIG Pulse M2 system for students who are training in marine seismic data capture and processing. They will be using sparker and boomer techniques with the same energy source SIG Pulse M2 which delivers from 100 to 2,000 joules. The sea acceptance tests (SAT) of June 2014 were performed around the Zhoushang Islands, one of the most famous China East Sea fishing locations. The result from both boomer and sparker were quite good, according to the supplying company Geo-Marine-Tech in China. The seismic data is recorded and processed with the Triton SB-logger system,...

Zen and the Black Art of the Boomer and Sparker System

Since the 1940s the use of an electrical spark to produce an underwater acoustic pulse has become an industry standard in the retrieval of sub-bottom profile data. Although conceptually simple, continuing demand for improved safety and technology for this type of equipment have spawned successively more advanced designs of Power Supply. From the very early EG&G and Teledyne units of the 1960s and 1970s to the second generation units of the 1980s and 1990s which gave rise to the adoption of solid state chargers and discharge devices, all have contributed towards reduced size, increased reliability and automatic discharge circuitry for...

S-Boom Technology for Fugro

Fugro Survey (Middle East) Ltd has ordered Applied Acoustics' S-Boom sub-bottom profiling system for its geophysical survey operations based out of Abu Dhabi (UAE). Developed for shallow-water, ultra-high resolution surveys, the S-Boom system had been undergoing extensive trials with Fugro during the late summer of 2011 before being accepted and selected at the end of that year.     S-Boom sub bottom profiling systems combine the power of three modified boomer plates to provide a single pulse, driven by a single source power supply. The fusion of these three transducers delivers a source level high enough to significantly increase sub-bottom... (read more)

S-Boom Delivers Triple Power

By harnessing the combined power of three of their Applied Acoustics 202 Boomer Plates to provide a single pulse, the Applied Acoustics’ S-Boom System is redefining the boundaries of shallow seismic surveying. Already recognised for producing high-resolution seabed profiles, the fusion of these three transducers delivers a source level high enough to significantly increase sub-bottom penetration without loss of data quality.       Capable of operating at a maximum energy setting of 1,000 Joules per pulse, and firing at three pulses per second, the S-Boom has achieved penetration results of over 200mS through sand and limestone whilst delivering the...

12-Element Streamer Hydrophones

Applied Acoustics have added a further streamer hydrophone to their range of sub-bottom profiling products. Up to now the company has offered standard streamer hydrophones with 1-8 or 20 element designs but from July it is introducing a 12 element hydrophone spacing, with the array calculated to offer the optimum resolution and penetration for either sparker or boomer applications.   The length of the hydrophone streamers, as with the other variants, remains at 4.5m with a robust 50m tow leader as standard, but the elements are spaced at 250mm. Extensive trials proved this was an ideal specification to bridge the... (read more)

SIG France Delivery to Meridata

Kim Ola, from Meridata Finland, has taken delivery of the SIG Pulse S1. The SIG Pulse is the new generation of energy sources developed by SIG France. It is a light energy source of 35kg, with the easy adjustment of the power: from 20 to 300 joules by small steps of 10 between 20 and 60 joules and steps of 20 onwards. This enables tuning of the energy according to the geological environment. Meridata integrates the SIG sparker/boomer with its multifrequency sub-bottom profiling systems. With the latest generation of dual-band chirps operating on frequency bands 2-9kHz, 10-20kHz, 20-40kHz, and the... (read more)
