Abstract

The analysis of 13 000 mi of continuously recorded bathymetric and seismic data in the Mediterranean Sea indicates a considerably different physiography and sediment distribution in the western and eastern segments. Seismic reflection profiling reveals much thicker accumulations of sediment in the Western Mediterranean than in the tectonically active Eastern Mediterranean. In the Balearic Sea, abyssal hills previously interpreted as salt domes have been identified over a large region in the subsurface. Bottom photographs taken on the Mediterranean Ridge show outcrops of an indurated or consolidated sediment, indicating either tectonic activity of the ridge or lack of accumulation of sediments.
