Test Center for Marine Investigation Equipment
As the sea does not have apparent topographical features like land while the water depth varies depending on the region, the maps based on a vertical reference plane have been used for the sea, which is different from the land. For navigation safety, it is necessary to obtain three-dimensional and reliable data on the tidal current, tides, navigational obstructions, etc., as well as undersea terrain through various marine investigations.
To this end, the Korea Hydrographic and Oceanographic Agency (KHOA) built a large-scale towing tank and related equipment and created a condition which is similar to the actual undersea environment. Then, a system is established to conduct performance evaluation on various marine measurement equipment, such as an echo sounder, hydrometer, and tide gauge, and to perform additional ocean-related experiments.
