- Model SES-2000 - Sub Bottom Profiler

0

From the wide range of 'Innomar SES-2000' parametric sub-bottom profilers the 'Innomar SES-2000 standard' model is the most versatile one: it is small enough to be used on small boats for inshore surveys but also powerful enough to be applicable for offshore surveys down to 500m water depth.

The high ping rate, small footprint and the possibility of transmitting sound pulses over a wide frequency range ensure sub-seafloor data with excellent resolution and very good sediment penetration. Electronicbeam stabilizationwill give good results under bad weather conditions, too.

A user-friendly data acquisition and system control software (SESWIN) provides the possibility for network remote operation as well as remote data visualization.

The 'Innomar SES-2000 standard' 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 SBP data.
