Increase the signal/noise ratio of the seismic records with a multi-channel coverage.
Our multi-channel streamers are dedicated to high and very high resolution seismics, with small diameter, short hydro spacings and group intervals.
Preamplification can be completed with a low-cut filter, depending on the energy source used.
The streamers are supplied neutrally buoyant, and can be ballasted to achieve the required towing depth, depending again of the emitted signal.

with SIG16 multi-channel streamers
and Delph Seismic acquisition system.
The spacing of the common depth points (CDP) depends on the hydrophones group-spacing of the array, the speed of the vessel, and the shooting rate.
The seismic signal of a particular point is identical for each channel, except for the noise which can thus be discriminated.
Exemple of the same profile from the west side of the island of Ouessant at about 200 km (courtesy of UBO Brest, team of JP Rehault), recorded with one channel, compared with a six-channel coverage.
DELPH Seismic Analog Acquisition Unit is the latest topside generation for acquiring seismic data. Embedding all necessary inputs and outputs, it accurately digitizes single to multi-channel seismic signals. Thanks to a single Ethernet output, acquired data is logged on any laptop or workstation running DELPH Seismic Acquisition software. This is a new standard for high-resolution seismic surveys with simplified integration, maintenance and operation.
