Innomar SES-2000 light Sub-Bottom Profiler

Innomar SES-2000 light parametric sub-bottom profiler The Innomar SES-2000 light sub-bottom profiler is designed for shallow-water applications inshore and near-shore at water depths down to 400 meters.

This 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.
