METHOD OF RECONSTRUCTING SEA-FLOOR RELIEF WHEN MEASURING DEPTH USING HYDROACOUSTIC APPARATUS

摘要

FIELD: physics. ^ SUBSTANCE: depth is measured with determination of an adjustment which is determined by the point where the hydroacoustic apparatus is installed. Vertical distribution of sound speed in water is determined from reflected signals. The sea-floor relief is reconstructed. The boundary zone which separates the continental slope from the shelf is selected from the obtained measurement results. The planetary structure of the sea-floor in the transition boundary zones between the slope and the shelf is determined by probing the sea-floor with acoustic waves and measuring the magnetic field. A tectonic map of transition boundary zones is constructed from the measurement results, from which the boundary of the continental shelf is determined by comparing planetary structures in transition boundary zones and planetary structures on dry land. The tidal level is additionally varied when measuring depth. ^ EFFECT: broader functional capabilities. ^ 1 dwg
