Sub bottom profiler
Innomar SES-2000 Light
The SES-2000 light sub bottom profiler is used to study the topography of the seabed and the structure of the sediment strata by registering with a receiving antenna signals of difference frequency emitted by an antenna emitter and reflected from the surface of the bottom and layers of sediments. According to the time of arrival of the reflected signals to the receiving device, the distance to the various layers of bottom sediments and their composition are determined.

Appointment

The SES-2000 light sub bottom profiler is used to study the topography of the seabed and the structure of the sediment strata by registering with a receiving antenna signals of difference frequency emitted by an antenna emitter and reflected from the surface of the bottom and layers of sediments. According to the time of arrival of the reflected signals to the receiving device, the distance to the various layers of bottom sediments and their composition are determined.

The principle of operation of the device

The result of the work of the sub bottom profiler is a profilogram, which shows the structure of the bottom relief and the geological section of the sediment thickness in the form of a graphic image. It is possible to use a profiler in the range of sea depths from 1 to 400 meters with a signal penetration of up to 40 meters into a given pound (depending on the composition of the soil, frequency and noise level).This profiler uses a signal with a primary frequency of 100 kHz. The secondary frequency (4 - 15 kHz) should be selected based on the followingcriteria: - the best signal-to-noise ratio; - maximum penetration depth; - High resolution.
