Resumé

Benthic foraminiferal assemblages were examined in two piston cores collected from the northern and southern bank of the lower Nazaré canyon. Whereas sedimentation on the southern bank is predominantly hemipelagic, the northern bank is greatly influenced by terrigenous sediment transport through the canyon. Over time this has resulted in construction of a levee of locally up to 1 km high. We investigated the response of benthic foraminifera to a variable supply of terrigenous sediment from the Last Glacial Maximum (LGM) to present.
