Multibeam and Singlebeam Bathymetric Surveys

Hydrographic Survey is the science of measurement and description of features which affect maritime navigation, marine construction, dredging, offshore oil exploration/offshore oil drilling and related activities. The term Bathymetric Survey originally referred to the ocean's depth relative to sea level, although it has come to mean Submarine Topography or the depths and shapes of underwater terrain. Echo sounding is a technique for measuring water depths by transmitting acoustic pulses from the ocean surface and listening for their reflection (or echo) from the sea floor. Echo sounding is done either by a single beam or multi-beam echo sounder. Single beam echo sounder make a single depth measurement with each acoustic pulse (or ping) and include both wide and narrow beam systems. A multi-beam echo sounder is an instrument that can map more than one location on the ocean floor with a single ping and with higher resolution than those of conventional echo sounders. Effectively, the job of a narrow single-beam echo sounder is performed at several different locations on the sea bottom at once. Our experienced survey team offers both single and multi beam bathymetric surveys in Middle East and North Africa Region and India.
