Reports findings of reconnaissance seismic surveys conducted on the north-east Grand Bank to study the near-surface sediments, assess the presence and characteristics of seabed geotechnical hazards, and examine the role of Quaternary glaciation and sea-level fluctuation on sediment distribution and characteristics. The regional setting is first reviewed and a refined regional stratigraphy is described based on new seismic data. Till deposits and moraine fields as observed from the seismic studies of the shelf glacial sediments are described. Finally, interpretations of the glacial history of the study area are offered and implications of the findings for offshore engineering related to oil & gas development are discussed.
