Mapping with Multibeam Sonar | Nautilus Live

Description:

Mapping the ocean floor aboard E/V Nautilus relies on our advanced Kongsberg EM302 Multibeam Echo Sounder - a tool that uses acoustic sound to "see" beneath the waves at the hidden features of the planet. This system emits sound in a fan-like pattern made of up to 864 individual sonar beams, covering a wide expanse beneath and either side of the ship. Operating at 30 kHz frequency, the system provides high-resolution bathymetric data down to 7,000 m, enabling precise mapping of the seafloor as Nautilus travels around the world. By precisely measuring the time it takes for sound to make a roundtrip journey from the ship to the seafloor and back, the system creates detailed 3D maps, aiding scientists and technical teams in their exploration of the ocean's hidden landscapes. -- E/V Nautilus is exploring unknown regions of the ocean seeking out new discoveries in biology, geology, and archaeology.
