Innomar SES-2000 smart Sub-Bottom Profiler

Innomar SES-2000 smart parametric sub-bottom profiler The Innomar SES-2000 smart model is the smallest member of the Innomar SES-2000 sub-bottom profiler family. It has been designed for inshore surveys in shallow waters down to 100 metres water depth using small boats, but can also be used in coastal areas.

Because of its small size and weight this system is convenient even on the smallest boat. Controlled via Ethernet using any Windows based PC or tablet it is a user friendly and affordable design, too.

The Innomar SES-2000 smart model is utilized on the Innomar SES-2000 autonomous unmanned surface vehicle (USV) for remote-controlled and autonomous surveys in sensible environments.

The Innomar SES-2000 smart model acquires full-waveform data that can be processed with any seismic software (SEG-Y format). Innomar also provides the ISE post-processing software specialized on the Innomar SES-2000 SBP data.

For survey examples please see the Extremely Shallow Water Applications and Shallow Water Applications.
