Sonar Interface Unit

The Octopus 160 sonar interface unit's design and is compact, rugged and weather-proof. Compatible with EdgeTech's work-horse 272TD dual-frequency side-scan sonar, it is simple to operate and is suitable for small boat use in many types of underwater survey. Housed in a rugged custom Pelicase, the 160 is highly portable and it can be operated with the lid closed allowing uninterrupted operation in harsh environments.   Another popular feature is the new user interface for all controls and once configured for a specific towfish, this needs no further adjustment. With direct connection to standard EdgeTech 272TD tow cables and full... (read more)

Sentinel Sonar Order

The US Naval Underwater Warfare Center (NUWC) in Rhode Island (USA) has placed a contract with Sonardyne Inc., Houston (TX, USA) for the supply of an additional Sentinel Intruder Detection Sonar system.     The announcement follows the completion of rigorous acceptance and readiness trials by NUWC in 2008 when Sentinel was shown to meet the US Navy's performance requirements for diver detection. The latest contract adds an additional Sentinel to the new Integrated Swimmer Defence System. This is being led by the Program Executive Office, Littoral Mine Warfare (PEO-LMW - PMS480) and the first Sentinel was delivered to NUWC... (read more)

Side-scan Sonar Demonstration

GeoAcoustics has launched Sonar 2094 Digital. A series of seminars and demonstrations were held by Simrad Spain, the local Kongsberg office, in November and December of the past year for their naval, scientific and industry customers. The capabilities of this technology for environmental mapping, engineering and archaeology surveys as well as object detection and classification were shown in various places along the Mediterranean coast.   Sonar 2094 Digital is the successor of the Dual Frequency Side-scan sonar, which was first launched in 1996 and developed into an industry standard, with over 1,000 units sold worldwide. Sonar 2094 Digital combines the... (read more)

3D Sonar Technology

The journey from oil and gas to homeland security and back again
Since its introduction many years ago, survey sonar has evolved steadily, but is still a difficult and non-intuitive survey tool, requiring large amounts of processing to arrive at the most basic end product. Initially, anyone wanting to survey or inspect the underwater environment was limited to single beam echo-sounders, in simple terms one-dimensional sonar, yielding very little quantifiable data. These in turn were developed into mechanically scanned sonars, and subsequently into today’s high performance multi-beam and forward looking sonars which are the back-bone of the survey industry. Even the very best commercially available multi-beam sonar delivers only 2 dimensional data... (read more)

Sonar in Fisheries Research

A year round study on fish migration
Fisheries acoustics has its origin in the marine environment. Only with the development of small elliptical beams has it become possible to apply sonar in shallow freshwater. Since 1992 the Organisation for the Improvement of Inland Fisheries uses sonar for fisheries research, in The Netherlands. The mean application of sonar in freshwater is fish stock assessment by means of a mobile survey. In addition, sonar equipment can be applied at a fixed location to study fish migration. This gives information on the exact timing, direction and relative number of migrating fish over time. To be sure of the absolute number,... (read more)

Side-Scan Sonar Deliveries

The MacArtney Group has during the winter and early spring delivered 6 EdgeTech 4200-FS side scan sonar systems in different countries. Three complete 300/600 kHz systems plus spares and one spare towfish has been delivered to The Royal Danish Administration of Navigation & Hydrography. This order also included 3 x 300 meter tow cable. One 4200 side scan system was sold to Geoconsult A/S in Norway for ROV installation and another AUV type 4200 system was delivered to Noordhoek, Holland, in connection with their purchase of 2 FOCUS-2 ROTV systems. The last system was delivered to GSI (Geological Survey of... (read more)

Forward-looking Sonar Upgrade

FarSounder will be launching a software upgrade for its FarSounder-500 and FarSounder-1000 forward-looking navigation sonars. The upgrade will increase the intuitive nature of the information and enhance users' understanding of the obstacles and sea bed ahead of their ship. The full release will be announced at SMM Hamburg and the Monaco Yacht Show later this year. At FarSounder’s recent customer demonstrations and technical training class, participants were introduced to a few of the upcoming new capabilities. A sampling of these features included Ping-to-Ping Sea Floor Stabilisation, Improved Sea Floor Imaging and Sea Floor Chart Overlay. FarSounder’s guests saw a demonstration... (read more)
