Occurrence of acoustic masking in sediments in two areas of continental shelf of Spain Ria de Muros (NW) and Gulf of Cádiz (SW)

Zones of acoustic masking in sediments in the continental shelf of Cádiz, and in the Ria de Muros have been mapped utilizing 3.5 kHz and Uniboom seismic reflection records. In Cádiz the masking may be generated by shell beds, source of the shells is a Pliocene conglomerate that corresponds to the ac...
