Side-Scan Sonar Seminar

L-3 Klein Associates announces a Side-Scan Sonar Operations and Maintenance Training Seminar from 9 October to 11 October 2007. The three-day seminar will be conducted at L-3 Klein's Facility in Salem (NH, USA). The training will include two days of classroom instruction and 1 day of on the water training.   This seminar is geared to the operator, as well as to the manager, who wants a better understanding of Side Scan Sonar techniques. The course is open to any user of side scan sonar regardless of brand, experience, or occupation. Topics covered will include Basic Sonar Principles; Types of... (read more)

SHADOWS Mapping Sonar

The delivery of high quality, repeatable data is of paramount importance for the successful collation of any large dataset, particularly when the data is acquired in a number of successive campaigns (as with EEZ mapping, route surveys, debris surveys, pre-seismic surveys, environmental characterization surveys, etc). IXSEAs SHADOWS Mapping Sonar is an innovation in seafloor mapping, that may give the answer.   Aside a Synthetic Aperture Sonar (SAS technology), SHADOWS combines automatic generation in real-time of high-resolution mosaic in GeoTiff format; high-accuracy positioning (the mosaic is generated from the fish position); 600 m true swath (no blind zone at nadir); coverage...

Simrad's New Sonar Direction

Simrad invited distributors from all over the world to join them onboard the M/V Finnmarken, which left Tromsø harbor on 5th October, reaching Trondheim on the morning of 7th October. Simrad presented three new sensors for its PI trawl monitoring system: the Geometry Sensor, Seine Sounder and combination Spread/Depth sensors.   The fisheries research community was well represented onboard M/V Finnmarken. Simrad's fishery research experts discussed the latest high-tech developments in its tools for fishery research, focusing on multibeam systems such as the ME70 Multibeam Echosounder and MS70 Multibeam Sonar.   63 delegates from 20 countries joined Simrad on the...

Navy Sonar Operations Proposal

NOAA's Fisheries Service is seeking comments now through 19th November on its proposed rule to authorise impacts to marine mammals during Navy training exercises around the Mariana Islands. The NOAA proposal includes protective measures designed to minimise effects on marine mammals.     The Navy has requested an authorization under the Marine Mammal Protection Act, because the mid-frequency sound generated by tactical sonar, and the sound and pressure generated by detonating explosives, may affect the behavior of some marine mammals, or cause a temporary loss of their hearing sensitivity.   NOAA's Fisheries Service does not expect the exercises to result...

CHIRP Sidescan Sonar System

Falmouth Scientific, Inc. (FSI) has reached into its well of experience and knowledge to develop the HMS-624 digital CHIRP sidescan sonar system offering dual simultaneous 100/400KHz frequency operation. The HMS-624 provides imaging capabilities for deep and shallow water applications. The twofish electronics incorporate FSI’s CHIRPceiver 24-bit CHIRP signal processing, which results in very-high-resolution sidescan data at towing depths of up to 2,000 metres. The Topside Power/Data Multiplexer Interface is packaged in a standard 2U 19” rack mount enclosure and provides a 4Mb/s DSL connection for the towfish and a standard Ethernet connection for the data processing computer. The system uses... (read more)

Forward-looking Sonar Simulator

BlueView Technologies recently teamed with Marine Simulation to develop a sonar simulator based on BlueView's line of forward looking multibeam imaging sonars. The new computer-based simulator is designed to be used with ROVsim Pro, Marine Simulation's flagship undersea ROV simulator and will be offered as an optional module later this quarter.   With the addition of BlueView's imaging sonar, ROV pilots can now quickly learn how to navigate in low visibility conditions using the sonar's real-time feedback.  This technique of ‘flying-by-sonar' can dramatically decrease an ROV's downtime resulting from poor water conditions. ROVsim simulators are currently being used by ROV... (read more)

Large Imaging Sonar Order

BlueView Technologies has received an order for one hundred (100) high-resolution P Series Imaging Sonar systems. In the coming months BlueView will deliver the compact, low-power 900kHz imaging sonar systems to VideoRay for integration onto their microROV systems providing their customers with real-time underwater search and navigation capabilities.     BlueView’s P Series Imaging Sonar are available with 3 field-of-view options – 45º, 90º, and 130º (the widest available), and operate in low or zero visibility conditions minimizing downtime due to water clarity conditions. Engineered to operate while in motion or from a stationary position, BlueView 2D Imaging Sonar enhance... (read more)

Compact Side-scan Sonar

Tritech has launched the StarFish 450H, a hull-mounted side scan sonar which produces spectacular images of the seabed. The compact, slim-line sonar design combined with flexible mounting bracket can be fixed on to any vessel and allows you to monitor the seabed for interesting targets during every journey.     With hull-mounted systems there’s no need to worry about snagging a towing cable when surveying in shallow or high traffic waters, making it very simple to operate. Its ease of use makes it an ideal system for anyone needing to capture digital images of the seabed on their own. Utilising... (read more)

Towed Underwater Camera and Sonar

A new concept of towed underwater vehicles has been presented by Oceanflite. Through the shape of their bodies, the TUVs can fly underwater. The depth of their flight is determined by the speed of the boat: the faster the TUV is pulled, the deeper it will float. The TUVs can be euqipped with sonar or an underwater camera, making the device fit for surveying jobs, fish finding or underwater inspections. Images can be displayed on an in-boat monitor.

Search & Recovery Side Scan Sonar

EdgeTech has introduced their 4125-P Portable Search & Recovery Side Scan System. The 4125-P is a digital single or dual frequency 400/1250 kHz system that produces very high resolution imagery. Designed with Search and Recovery and Harbor Security in mind, the system can quickly be deployed by one person within minutes from a very small boat and a 12-24 VDC power source. The 4125-P comes standard with a lightweight towfish in a rugged portable carrying case, portable waterproof topside processor with laptop computer and 50 metres of tow cable.       (read more)
