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)

New Sparker for UST21

UST21, a South Korean offshore survey company, has acquired the new SIG Pulse M2. The sparker has been chosen to complement the geophysical equipments pole, with now 2 subbottom profilers, 2 sparkers, and 1 magnetometer. The SIG sparker will be used for high-resolution subbottom profiling and to improve penetration due to the frequency range of around 1,000Hz. Based in Busan, Underwater Survey Technology 21 is specialised in geophysical surveys, offshore support and resource exploration. Image: SIG Pulse M2 - 2000 joules energy source. (read more)

Mini-sparker for University of Perpignan

The University of Perpignan (France) has come into possession of the new generation of SIG mini-sparker. The SIG Pulse S1 is a 35kg energy source with easy power adjustment: from 20 to 300 joules in small steps of 10 between 20 and 60 joules and in steps of 20 above that. This enables the energy to be tuned according to the geological environment. The CEFREM is a research unit of the university specialised in the coastal environment. The researches are focusing on material and energy transfers at the interfaces of the coastal system. The research team is composed of sedimentologists,... (read more)

SIG 2mille Sparker In Hangzhou

The 2nd Institute of Oceanography, SOA, in Hangzhou, is now ready to operate their new seismic equipment. The technicians of the Institute have been trained by SIG during the FAT, to use the energy source and easy-replaceable sparker-tips. The model of sparker-tip is chosen according to the water-depth conditions, and the energy levels used. The 2nd Institute owns a SIG 2mille system, operating between 60 and 2000 joules. (read more)

Sparker System for Chinese Academy of Geological Sciences

Orangelamp from Beijing, China, has signed a contract with the Chinese Academy of Geological Sciences (CAGS) for the supply of a new SIG Pulse L5 sparker system. CAGS is an organisation engaged in geoscience research. The expected working depth will be within 2,000m. The L5 is the extended version of the SIG Pulse M2, which allows the user to go from the shallow-water environment to deeper waters. The second extension box increases the power to 6,000 joules if necessary. SIG France has appointed Orangelamp to represent the company in China. Orangelamp is well established in the geophysical land environment and... (read more)

Mediterranean Survey for Applied Acoustics’ Deep Tow Sparker

The Applied Acoustics deep-tow sparker, the DTS-500, has recently been deployed in the Mediterranean Sea, off the continental slope of Majorca, working on a project with SOCIB, the Balearic Islands coastal observing and forecasting body. Assisted by Carlos Castilla Álvarez, SOCIB’s oceanographic instrumentation technician, the DTS-500 was deployed in deep water, up to 500m, at a distance up to 1km from the SOCIB research vessel. The researchers achieved greater than 60m penetration and with increased data resolution, up to 15cm, they called the sub-bottom profiling results excellent across the full-working depth range of the DTS-500, according to Neil MacDonald, project...

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,...

Successful Sea Trials For SIG Pulse M2 Sparker

Guangzhou Waterway Bureau, China, has approved the performance of the new SIG Pulse M2. The sparker system has been tested on the site of the bridge project that will connect the west side of Hong Kong to Macau and the mainland Zhuhai. The Hong Kong-Zhuhai-Macau bridge will cross the Pearl River estuary. Part of the project is a sub-sea immersed tunnel of 6.7km. The project area must be covered by a seismic reflection sparker. The SIG Pulse is the lightest system available on the market to install and operate on board any geophysical vessel or vessel of opportunity. The energy... (read more)

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...
