Bathymetry and Bottom Structure of Zones Near the Island of Elba Used for Acoustical Trials in Shallow Water

摘要

Two shallow-water zones situated north and south-east of the island of ELBA have been surveyed to obtain information about the bottom conditions. The area to the north of the island has a depth of 100 m to 130 m and a very flat bottom covered with clay and sand-clay sediments. The area to the south-east of the island is of the same depth and has a flat bottom covered with clay sediments. In this area a very strong acoustic reflector exists under the sedimentary layer.
