Definition
- The Kongsberg Simrad EM-3000 Multibeam system is a high-resolution echo sounder which measures depth accurately to within several centimeters when post-processed. It not only measures the depth below the vessel but also out to the left and right of the vessel at a range of ~2-4 times the water depth. The location and vertical elevation of the vessel are tracked by the integration of three global positioning systems working together with the echosounder. The multibeam bathymetry is relayed to a Sun Ultra 5 workstation, where it is stored, processed, and presented on screen. Finally, the post-processed image is printed at high resolution with each dot/pixel of color representing ~ 0.3 - 0.6 square meters (~1- 2 square feet). (en)
