Sleeve-gun, 3.5-kHz, and 12-kHz profiles from the Labrador Slope provide the basis for an analysis of sedimentary facies, processes, and evolution of a continental slope adjacent to an ice margin. The upper slope is deeply incised by numerous canyons reflecting headward canyon branching. The less rugged middle-slope topography has fewer canyons and large slide and slump scars followed downslope by debris-flow deposits. Echo character of seismic profiles reflects the difference in sediment types supplied from mud-dominated sources and sand-, gravel- and till-dominated sources. On the rise, debris-flow deposits are largely confined to canyons. Intercanyon areas are dominated by spill-over turbidites alternating with hemipelagic sediments, which on some of the southern to southwestern levees occur in sediment-wave fields formerly attributed to bottom-current activity.
