ABSTRACT:
A bottom system related to equipment deployed for seabed geo-electrical survey is proposed, in preferred embodiments comprising a basic module, including registration and power supply means, or a combination of the basic module with at least one additional module: a magnetic characteristics measuring module or/and a seismic characteristics measuring module. The additional modules are connected with other modules through hermetic connectors. The modules are attached to a load with Kevlar straps, provided with an electrochemical release system. Arms with electrodes measuring electromagnetic characteristics of seabed, are attached to the basic module, in their initial position directed upwards at minimum 15° from the vertical, and fixed with fixing elements, connected with a releasing element of a device for descending and lifting the bottom station. The arms are made telescopic for convenient transportation. Independent embodiments without additional modules include a non-conductive conical member joined to the basic module and to the load.
