The late middle to late Wisconsinan Laurentide ice sheet terminated at the edge of the Scotian Shelf ca. 21 ka, in close temporal agreement with the H-2 Heinrich event of the North Atlantic stratigraphy. The ice began its recession along the western

A refined synthesis of the stratigraphy of the Scotian Shelf is presented, based on recently published borehole and seismic-reflection data and detailed correlation along high-resolution seismic profiles between the outer banks and the central basins

Till is of common occurrence in the marine environment and can be both subglacial and proglacial in origin. Former glacial margins are often represented by till tongues, that are interbedded with stratified glaciomarine sediment, and the relationship

Seismostratigraphic studies on the Scotian and mid-Norwegian Continental Shelves have led to the development of a conceptual model for glacial deposition and erosion by ice sheets in a marine environment (till-tongue model). Some of the terminal depo

Analyses of seismic reflection profiles supported by lithological and palynological studies of core samples from submarine outcrops indicate that the lower Paleozoic succession of the Avalon Terrane, southeast Newfoundland, is continuous offshore. Th

Four erosional unconformities have been recognized within the Mesozoic-Cenozoic succession on the Scotian Shelf, on the basis of data from high resolution seismic reflection profiles. Older unconformities are known from well data and others may be re

This paper presents the results of a comparative study of pockmarks and associated features appearing on both sides of the North Atlantic: on the Scotian Shelf off Nova Scotia and in the northern North Sea. Pockmarks are formed in seabed material con

A study of processed seismic reflection profiles along the eastern Canadian continental margin indicates the occurrence at depth of paleocontinental slopes of Cenozoic–Mesozoic age, generally in the vicinity of the present continental slope. The pa

Pockmarks, cone-shaped depressions that occur in unconsolidated fine sediments at the seabed, are generally thought to be formed by gas ascending from underlying sediments. A mosaic of pockmarks in Emerald Basin on the Scotian Shelf was constructed a

A side-scan sonar survey along the western bank of the Laurentian Channel and on the western Grand Banks revealed the occurrence of iceberg furrows that are probably of Late Pleistocene age. The occurrence of furrows in the Gulf of St. Lawrence is si
