FIELD: technologies for measurement of specific electric conductivity of sea bottom.
SUBSTANCE: the system contains a large number of blocks, each block representing a unit, made with possible positioning in place on sea bottom for measuring horizontal electrical and magnetic fields. To the block unit, a vertically oriented rigid bar is attached and stretched vertically from it. The bar has a pair of electrodes, shifted vertically, which form a vertically oriented dipole antenna. The electrodes are in electric connection with the amplifier positioned inside the unit. Signal from the amplifier is dispatched to data registration processor, which is also positioned inside the unit. By means of the processor, time series of amplified signals of electric and magnetic fields are accumulated over a given time period.
EFFECT: usage of vertical field for measuring transverse changes in the geological structure of sea bottom.
