SES-2000 light Sub-Bottom Profiler
The SES-2000 light sub-bottom profiler is designed for shallow-water applications in near-shore and inland waters down to 400m.
There is an integrated control PC and included features like full-waveform data acquisition and multi-frequency signals give advantages compared to the SES-2000 compact model.
SES-2000 light parametric sub-bottom profiler echoprint data example
(frequency 10kHz; range 170–310m; sediment penetration up to 50m at about 250m water depth).
Some more data examples are shown in the Extremely Shallow Water Applications and Shallow Water Applications sections.
