China Maps Ocean Floor as It Builds Submarine Warfare Capability
need information about underwater terrain to avoid collisions and hide their vessels.But that data is also essential for detecting submarines, which operate within a few hundred meters of the surface. Typically, submarines are identified through the sounds they emit or echoes from signals sent by sonar systems. Tom Shugart, a former U.S. submarine commander who is now an adjunct senior fellow at the Center for a New American Security, said the movement of those sound waves changes depending on the underwater landscape.Sound waves and submarine movements are also affected by water temperature, salinity
Breakthrough Technology Unveiled at Oceanology International
Water Partners earlier this month, is building a differentiated platform focused on technologies that enable greater understanding and visibility beneath the ocean surface.The company announced the acquisition of Sound Metrics, a leading developer and manufacturer of high-resolution acoustic imaging sonar systems used in underwater inspection, monitoring, and security applications.“Sound Metrics brings highly differentiated technology and a strong reputation for innovation in underwater imaging,” said Mike Read, Chief Executive Officer of OceanSight. “Together with Ocean Floor Geophysics

How Impact Subsea's ISS360 Series is Redefining Compact Sonar
Impact Subsea, a leader in subsea sensor technology, has continued to develop their ISS360 Imaging Sonar range.Since its debut in 2020, the ISS360 is a solution for ROV and AUV navigation and target identification, offering a replacement for legacy scanning sonar systems.A Five-Year Journey Launched in March 2020 as the world’s smallest scanning, imaging sonar, the ISS360, was designed to provide a step-change in capability for the underwater vehicle market.The ISS360 Imaging Sonar has undergone development, evolving from the world’s most compact, scanning sonar into a high-definition
Schmidt Ocean Institute Advances R/V Falkor (too)’s Mapping Capabilities
;June 28) in Talcahuano, Chile, the team reconstructed the bow of R/V Falkor (too), transforming it from a bulbous bow more common on offshore commercial vessels into a streamlined, V-shaped bow optimized for science missions. The new bow improves the precision and reliability of the ship’s sonar systems in capturing high-quality mapping data, even in challenging weather conditions. It can now capture high-resolution data in 6-11 knots (~7-13 mph) and in swells exceeding three meters.R/V Falkor (too)’s new bow helps to eliminate bubbles from interfering with the ship’s sonars and
