However, the underwater environment of Taiwan Bank is complicated. To better understand the battlefield conditions of Taiwan Bank, Republic of China Navy (ROCN) should better investigate and study morphological, hydrological, and sub-bottom characteristics in this area. Compared to mainland China, which has investigated Taiwan Bank for several years, Taiwan has relatively limited data on Taiwan Bank area. Moreover, sand pump dredgers from mainland China have often entered Taiwan Bank for sand resources recently. This is the second-year project of the three-year project entitled “Seafloor Morphology Investigation and Study”, which is a sub-project of the leading project “Observations of Ocean Current around the Taiwan Bank”. It aims (1) to collect and integrate historic bathymetry and sub-bottom profile data in the Taiwan Bank; (2) to investigate Taiwan Bank area by using advanced multi-beam echo sounder (MBES) systems of Taiwan’s New Ocean Research Vessel; (3) to develop and apply a sub-bottom characteristics analysis technique based on MBES seabed backscatter data. All observation results in this project will provide to ROCN for naval operations. Our results not only provide morphological parameters and seabed characteristics of Taiwan Bank but also can help ROCN to gather environmental intelligence of Taiwan Bank better. Furthermore, those parameters can be important information for ROCN to improve the predicting models.臺灣灘;多音束水深;底質剖面;新國家研究船隊;Taiwan Bank; Multi-beam echo sounder; Sub-bottom profile; New Ocean Research Vessels
