Remote wireless control We've done it for years. Using standard off-the-shelf computer hardware, the Simrad EK60 scientific echo sounder system MAXIMIZING YOUR PERFORMANCE AT SEA

Wireless applications scientific echo sounder several years. Many environments, have sounder control. River surveys controlling and transferring data from the EK60 is by using a plug- and-play off-the-shelf radio link. The cost is less than 50 Euro, and ideal solution for rivers and other freshwater applications. A recent trend among Marine Institutes is to establish a reference fleet of commercial fishing vessels to collect scientific data. EK60 echo sounders onboard fishing vessels are remotely operated via satellite link from the respective research institutes, where the scientist can...

Wireless applications The Hugin Autonomous Underwater Kongsberg Maritime is used for many offshore applications, including fisheries research. The Hugin operates autonomously or operator supervised for up to 60 hours using inertial navigation. EK60 echo sounders onboard the Hugin are controlled, and data are transferred, via an acoustic telemetry link to the research vessel. shown with a D-link communication using off-the-shelf computer equipment shown, but this directional antennas.

Simrad EK60 Scientific sounder with multiple frequency operation In cooperation with the Institute of Marine Research in Norway, Simrad has developed an echo sounder system capable of discriminating between different fish species. www.SIMRAD.com MAXIMIZING YOUR PERFORMANCE AT SEA

Simrad EK60 Scientific echo sounder system Recent research has shown several discrete echo sounder frequencies (multifrequency) not only improves fish stock estimates, but can also be used This is because each specie has a unique acoustic frequency response. This new and growing understanding greatly improves the value of hydroacoustics to obtain information about marine resources. Scientists at the Institute of Marine Research, Norway, have shown that different species of zooplankton and fish can be identified based on multifrequency acoustics. 'acoustic signatures' for the different...

Simrad EK60 Scientific echo sounder system Multi-frequency echo sounder samples Small organisms like many plankton species will normally have the strongest sound reflection in the higher end of this frequency range. The echograms below are kindly provided by NOAA. Using 18 and 200 kHz, they clearly demonstrate that the reflective properties of aquatic animals can be strongly frequency These dual frequency echo sounder samples shows simultanous recordings of the same water column using two different frequencies. The echograms illustrate the detection of age-0 walleye pollock and capelin (A)...

Marine computer for reliable operation echo sounder system can be computer, provided that the However, office computers have not proven to be very dependable on fishing vessels. In order to meet an increasing Based on a commercial design. the ES60 Marine Computer provides a rugged design, small physical size. adequate performance and no moving The traditional hard disk has been replaced with a 4 Gb FlashDisk memory device, while fans and CD player has been omitted. The computer supports four RS-232 serial lines, two ethernet will also operate on DC voltages. MAXIMIZING YOUR PERFORMANCE AT...
