Bình Châu is a safe sea for ships to anchor and avoid storms, it is an important position on the trade route through the East Sea from China, Japan to Southeast Asian countries, and going further to India and West Asia. It is necessary to survey and assess the potential of cultural heritage in this area using research methods of maritime archeology. Due to subjective and objective reasons, research, survey and training activities at sea here in the years 2018-2019 encountered certain difficulties. The remote sensing survey using side scan sonar and sub-bottom profiler detected traces of a boat at a depth of 9.2m and 78 targets. Surveys along the coast and in the vicinity of Bình Châu Bay show that in Gành Tre and Gành Lá Ngái, there may be traces of shipwreck dating from the 17th-19th centuries and an ancient current flowing into the Bình Châu Bay. In the future, it is necessary to continue to conduct surveys and combine interdisciplinary research in this area to better understand the role of Bình Châu Bay in history.
