| | | Vessels of opportunities 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 take full control of all echo sounder functions. | | |
| | | The Simrad EK60 scientific echo sounder system has been on the market for several years. Many scientists, both in the marine and freshwater environments, have chosen a wireless solution for data transfer and echo sounder control. Remote control and data transfer has become a natural part of several EK60 installations. | | |

| | | River surveys The simplest way of remotely 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 ranges are up to 1000 m. This is an ideal solution for rivers and other freshwater applications. Ocean HUB The Ocean HUB project uses EK60s in special water- and pressure proof housings. These are mounted on the bottom of a Norwegian fjord at 400 m depth. The transducers are pointed upwards creating an acoustic fence to monitor the flux of herring to their winter habitat. The echo sounders are connected to a remote land station using cables. From there, they are controlled, and data transferred, by means of a telemetry link. | | |
