Derinsu Underwater Engineering & Consulting, Turkey, has ordered the ultra-high resolution sonar system SeaBat 7125-SV to add to their pool of SeaBat sonar systems.
Derinsu is an underwater engineering company located in Ankara, performing nearshore and offshore surveys. The company will use the SeaBat 7125-SV system for high-resolution pipeline surveys and geophysical surveys in and around Turkey. Derinsu has previously conducted numerous surveys using SeaBat sonar systems, including surveys of the Nabucco Gas Pipeline Marmara Sea Crossing offshore route.
Members of the US Geological Survey were filmed while out on the Missouri River at Williston, North Dakota, USA, performing a hydrographic survey to monitor the state of riverbed erosion. They were using a multibeam echo sounder which transmits sound energy and analyses the return signal (echo) that has bounced off the riverbed or other objects. Multibeam sonars emit sound waves from directly beneath a ship's hull to produce fan-shaped coverage of the riverbed.
