Continental slope and basin sedimentation adjacent to an ice-margin: a continuous sleeve-gun profile across the Labrador Slope, Rise and Basin

摘要: Publication of continuous seismic profiles in atlas format permits direct comparison differences evolution major architectural elements modern continental margins. The accompanying > 700 km long sleeve-gun profile across the Labrador Margin (Fig. 2.1(a)) and basin floor 2.1(b) (c)) shows Quaternary a margin adjacent to waxing waning ice-caps.
