SeaSprite Sonar for VideoRay

VideoRay LLC announced that Tritech International has produced the SeaSprite sonar as a new accessory for the VideoRay ROV. The SeaSprite weighs just 5 ounces in water and is ideal for small ROVs and AUVs in military and covert uses. By equipping the VideoRay with the SeaSprite sonar, obstacles can be located, identified, and measured in low visibility environments. The SeaSprite simply plugs into any VideoRay Pro II and features an extremely fast scan rate to match VideoRay's high maneuverability. No calibration is needed. When plugged into a Pro II, the SeaSprite can be used in low visibility conditions and... (read more)

Side-scan Sonar Demonstrations

During Ocean Business 2009, L-3 Klein will be running live demonstrations of the L-3 Klein System 5000 V-2. The demonstrations will be conducted on-board the Bill Conway on Tuesday, 31st March at 1530, Wednesday, 1st April at 1400 and Thursday, 2nd April at 1030.     The L-3 Klein System 5000 V2, with the added swath bathymetric capability, employs advanced Interferometric signal processing to produce simultaneous estimates of the seabed topography out to the full swath extent of the sonar, typically 10 to 12 times the overall altitude of the tow fish. This added seabed topographic measurement is post processed... (read more)

Didson Next-generation Sonar

Sound Metrics Corp, UK, the manufacturer of the high-resolution Didson multi-beam sonar, has developed its next-generation sonar, ARIS (Adaptive Resolution Imaging Sonar). The ARIS uses the same Didson technology to produce crisp and clear images. During Oceanology International, the Sound Metrics Corp featured the ARIS 3000 mounted to an X2 rotator in a water tank. With 128 beams operating at 3MHz, the ARIS Explorer 3000 collects more data than any other imaging sonar in its class. All of the ARIS Explorer models work in zero-visibility conditions and are built to deliver in the most challenging conditions. In addition, the small... (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...

Quick-deploy ‘PulSAR’ Sidescan Sonar

Kongsberg Maritime, Norway, has introduced a tow fish sidescan sonar for use in search and recovery (SAR) missions as well as underwater inspection, engineering and scientific surveys. Developed by Kongsberg Geoacoustics, PulSAR is designed for intuitive operation and easy deployment by non-specialised personnel, enabling effective short-notice surveys using vessels of opportunity. The PulSAR system acquires high resolution acoustic images of the seabed using a compact, rugged stainless steel tow fish that is operated with a water protected (IP66) deck unit and small cable hand reel. The system can be deployed on small vessels such as open RIBs. Large areas can... (read more)

ROVs and Sonar for Universities

Many universities are now adding ROVs to their marine science programs. These remote-controlled camera systems can assist in a multitude of operations including underwater archaeology, monitoring the health of benthic habitats, behavioral studies of fish and other marine species, and performing specialized research. In addition to their high-resolution cameras and lighting, the ROV can carry a variety of other sensors including sonar to explore beyond the range of visual sensors, manipulator arms for sampling, and temperature and depth probes to measure and record environmental conditions.   One of the schools that recently acquired an ROV is King Abdullah University of...
