SES-2000 ROV Sub-Bottom Profiler

SES-2000 ROV parametric sub-bottom profiler for operation on remotely operated vehicles (ROVs) The SES-2000 ROV model performs like a SES-2000 standard SBP and is intended to be used on ROVs diving up to 2,000m below sea level.

The 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 along track (pitch) is used to compensate ROV tilt when following the seabed.

A user-friendly Windows data acquisition and system control software (SESWIN) is used for network remote operation. SES-2000 ROV systems are able to acquire full-waveform data that can be processed with any seismic software (SEG-Y format). Innomar also provides it's ISE post-processing software specialized on the SES-2000 data.
