A preliminary sonic prospecting by a sparker system was carried out on the Antarctic continental shelf on board the icebreaker FUJI. The results are as follows : 1) A ridge which seems to be a drowned lateral moraine was found in Amundsen Bay, 2) the broad rise north-northwest of the Ongul Islands is an erosional surface, at least its northern part.
