Submarine topography and seafloor image survey of Jukbyeon port in Uljin, South Korea using multi-beam echo sounder and side scan sonar

Abstract

We conducted submarine topography and seafloor image survey from 4, Mar. 2013 using R/V Jangmok2(35 ton), multi-beam echo sounder EM3001(Kongsberg corporation) and side scan sonar 4125(Edge Tech corporation). We used EM3001 multi-beam echo sounder and 4125 shallow water sides can sonar for survey. Multi-beam echo sounder is a device for observing and recording the submarine topography using sound. We mounted the EM3001 on right side of the vessel. Multi-beam echo sounder transducer commonly to mounted at right angles to the surface of water. However, we tilted 20-degrees of transducer for long range with 85-degrees measurement on the right side of the vessel. This exploration can see the sediment and waste materials accumulated in port. The maximum depth was 12m and We saw a lot of forsaken tire in the port. Such multi-beam echo sounder survey and side scan sonar survey will facilitate the management and the improvement of environment of port. sounder and 4125 shallow water sides can sonar for survey.
