SES-2000 standard Sub-Bottom Profiler
From the wide range of SES-2000 parametric sub-bottom profilers the SES-2000 standard model is maybe the most versatile one: it is small enough to be used for mobile installations on small boats for inshore surveys but also powerful enough to be applicable for offshore surveys down to 500m water depth.
A high ping rate, a small footprint and the possibility of transmitting sound pulses over a wide frequency range ensure echoprints with excellent resolution and very good sediment penetration. Electronic beam stabilization will give good results under bad weather conditions, too.
A user-friendly Windows data acquisition and system control software (SESWIN) provides the possibility for network remote operation as well as remote data visualization.
SES-2000 standard systems are able to acquire 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 SES-2000 data.
