ABSTRACT:
The invention relates to a device for measuring the impedance of a medium along a measurement line, the medium being either sea water or a sediment on the sea-bottom or else a mixture thereof. According to the invention, a special antenna (2) is used, which extends along the measurement line and contains a succession of ring electrodes (10, 11), which can selectively be fitted into a meter circuit (FIG. 2) via cyclically switched Reed relays (34, 35). The invention can especially be applied to the study of the alterations of a hole in a sediment at sea-bottom created behind a torpedo-shaped container penetrating by gravity into the sediment.
