SIMRAD EK80 Scientific Echo Sounder System

The SIMRAD EK80 scientific echo sounder system consists of sensors (transceivers), a wideband transceiver (WBT), a computer (PC), an Ethernet switch, and a display. It offers stable performance and excellent data quality, providing high-resolution digital echo and signal strength data. The system is widely used for studying ocean internal waves, water column echoes, seabed topography, fish schools, species identification and distribution, fisheries resource assessment, and monitoring fish passages and cages. Paired with post-processing software, it supports efficient analysis and visualization of ocean physical and chemical phenomena, seabed morphology and sedimentation, and marine biological distributions for scientific research.
