Sediment Dampens the Impact of Glaciation on Cenozoic Denudation

by Ann Rowan 9 September 20244 September 2024

Rates of continental-scale sediment flux and denudation are similar between glacial and interglacial periods when the aggradation of glacier-eroded sediment inhibits fluvial erosion downstream.
