Seabeam
Quick Summary
Seabeam is a sophisticated acoustic technique used in oceanography for bathymetry, which is the measurement of ocean depth. Unlike earlier methods that involved lowering ropes, Seabeam uses sound pulses to map the seafloor.1
This technology emits sound waves that travel to the ocean floor, reflect back, and are then analyzed. By calculating the time it takes for the sound to return, scientists can create detailed, two-dimensional maps of the seafloor's topography, including features like mountains and plains. This allows for a much more accurate and comprehensive understanding of the ocean's shape and features than traditional methods.21

…techniques as those that employ Seabeam and Gloria (Geological Long-Range Inclined Asdic) permit mapping two-dimensional swaths with great accuracy from a single ship. These methods are widely used to ascertain the major features of the seafloor. The Gloria system, for example, can produce a picture of the morphology of a…
