The so-called "Marine Testing Field (MTF)" is a concept to set up a natural site so that a laboratory experiment may be implemented directly at sea. In viewing the geographical advantage of National Sun Yat-sen University (NSYSU), an MTF has been proposed near the Shziwan bay area, which is particularly suitable to conduct research on near shore processes and harbor monitoring and protection. The purpose of this study is implemented the first phase towards the establishment of Shziwan MTF, that is, to conduct a complete survey of this area, including topological, morphological, geological, and dynamical properties of this area. The survey employs various equipment including sidescan sonar, subbpttom profiler, multibeam system, and seabed sampling, etc. To achieve a good quality, the survey routes were carefully planned, and 10 seabed samples were taken. The results have shown that the slope of the seafloor is about 145:1, indicating that the area has a very slow varying topography. Sidescan images have been carefully analyzed, and several objects on the seabed have been identified; furthermore, the subbottom images have shown layering structure in this area. The seabed sampling shows that the seabed is mostly consisted of fine sand with average particle size of about 0.263 mm. Overall, the field already explored shows that it is about 4116725m2 in area, in which 88.1% is sand, 7.2% sand with ripple marks, and 4.7% rocks.
