What does a SeaBeam do?
What does a SeaBeam do?
The SEA BEAM 2112 is a multibeam survey system that generates data which allows the production of wide-swath contour maps and sidescan images of the seafloor. It transmits a sonar signal from projectors mounted along the keel of the ship.
How do scientists make maps of the ocean floor?
Echo sounding is the key method scientists use to map the seafloor today. The technique, first used by German scientists in the early 20th century, uses sound waves bounced off the ocean bottom. Echo sounders aboard ships have components called transducers that both transmit and receive sound waves.
Who made the SeaBeam?
Starting in the 1970s, companies such as General Instrument (now SeaBeam Instruments, part of L3 Klein) in the United States, Krupp Atlas (now Atlas Hydrographic) and Elac Nautik (now part of the Wärtsilä Corporation) in Germany, Simrad (now Kongsberg Maritime) in Norway and RESON now Teledyne RESON A/S in Denmark …
How does a multibeam sonar work?
How does it work? Unlike single beam sonar, which uses just one transducer to map the seafloor, a multibeam sonar sends out multiple, simultaneous sonar beams (or sound waves) at once in a fan-shaped pattern. Backscatter is a measurement of the intensity of the sound echo that reflects back to the multibeam array.
What do maps of the ocean floor made by SeaBeam technology rely on?
SeaBeam technology uses sonar to map the ocean floor from a ship.
How has the multibeam improved our knowledge of the sea floor?
Combined with automated contouring, multibeam systems produced the ability to make detailed, complete maps of large areas of the sea floor, which became available to the scientific community for the first time in the late 1970s, after the Navy declassified the technology.

What is a sea bream?
Sea bream are popular for eating in Europe. The sea bream’s body shape is its main distinguishing feature. Their color varies widely from species to species, mainly depending on water type and environment. In brackish waters, for example, the fish tend to be darker, with shades of blacks and grays to help them blend in with the environment.
