On the origin of submarine canyons

Auteur :
VAN-BERCKEL F. L.,

Description :
It is suggested that the origin of submarine canyons depends on two factors: 1.a drop of the ocean level below the shelf/slope rim as a consequence of the formation of enormous ice masses during a glaciation. 2. the presence of powerful streams, created by the melting of ice masses| these streams carried large amounts of glacial debris across the shelf and deposited them on the continental slope. Continuous overloading of these debris piles resulted in debris avalanches downslope, which excavated canyons and ultimately formed large submarine fans.
