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...

Portable Side-Scan Sonar

The HMS-1400 Side-Scan Sonar System is a part of Falmouth Scientific's new Hegg Marine Solutions Division, specialising in products and services for the hydrographic and marine survey markets. The HMS-1400 is a low-cost, portable, single- or dual-frequency side-scan system. Powered by GeoDAS software from Oceanic Imaging Consultants, the HMS-1400 comprises a portable tow fish and waterproof topside case containing the data acquisition, control and power supply.  The HMS-1400 is ideal for harbour security and hazard surveys, search and rescue operations, and small-vessel surveys. Dual-frequency options from 100 through 1200 kHz max allow for best range/resolution selection for specific applications. The... (read more)

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...

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)

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)

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)
