March 2005 41 RV Dyson Outfitted with Simrad Simrad, Inc. of Lynnwood, Wash., recently outfitted RV Dyson with a full complement of state-of-the-art fish location and monitoring equipment. Among the array of sophisticated electronics available to researchers is a split-beam Simrad EK60 Scientific Echo Sounder. This new-generation fisheries research tool operates on four frequencies (18 kHz, 38 kHz, 120 kHz and 200 kHz) and is designed to provide accurate echo sounding, data storage, data analysis and report- ing of results. The vessel also includes a Simrad SM2000 Multibeam Echo Sounder, specially engi- neered for bathymetric survey and vertical water col- umn target detection. RV/Dyson was also outfitted with a Simrad FS20/25 Trawl Sonar system that pro- vides the bridge with real-time images of fish targets and net operation. This is augmented by Simrad's ITI Wireless Trawl Positioning and Monitoring System, which uses small battery-powered sensors mounted on the trawl to transmit important information to the bridge. With this sophisticated equipment, researchers can monitor the exact position of the vessel's gear as well as what is happening in and around the trawl.

The objective of the survey is to provide geo-referenced multibeam data, which is used to determine the progress of Bean-Stuyvesant's 12.8-cu.-yd. yard BH Dredge, MARICAVOR, working on the Key West Harbor, Fla., dredging project. The deliverables include color-coded plots of the acceptance areas.
