A trial excavation of underwater cultural properties at Dongsam site in Busan has been conducted. The site is located in the vicinity of Dongsam shell mound. The trial excavation consists of the shore investigation and the underwater investigation. For the shore investigation four trenches were digged. For the underwater investigation twenty boreholes were cored, and sediments at four predetermined sites were removed by air lifting technique. From the trial excavation a stump of a tree with many pieces of wood, and a few fragments of earthenwares were found. A comprehensive study of the trail excavation might furnish data for studying ancient coastal environment.
