Bathymetry

Bathymetry

Bathymetry is the science of measuring the depths and relief of the ocean to determine the topography of the sea floor. This technique maps the depth of water columns. A complete bathymetry system combines a water column measuring instrument (echo probe) and a positioning instrument (DGPS or RTK). Géosig, through its partner Géophysique GPR, is able to meet all your bathymetry requirements since we have systems ranging from single-beam bathymeters to multibeam devices and state-of-the-art helicopter-borne ground penetrating radar. Bathymetric sounders work like sonars, emitting sound vibrations, detecting their echo after bounce off the bottom and determining travel time. The information thus provides a horizontal or two-dimensional profile. Applications of bathymetry: Hydrographic surveys for boating safety; Production of digital models of the seabed for engineering design (tunnel layout, pipeline, bridge); Dredging control; Hydroelectric projects; Geotechnical and engineering studies. A convention using color codes makes it possible to map the seabed in a standardized way (General Bathymetric Chart of the Oceans or GEBCO, established under the aegis of the Intergovernmental Oceanographic Commission and the International Hydrographic Organization).
