Abstract
The results of a reconnaissance study of the surficial and near-surface bedrock marine geology of the Grand Banks of Newfoundland are presented. On the basis of high-resolution seismic reflection profiles, sidescan sonograms, and bottom samples, the position of a Late Wisconsin low sea level stand is tentatively identified at 110-120 m. Above these depths, glacial sediments were eroded and redistributed during the Holocene transgression. Stable areas of lag gravel and large patches of sand have been deposited. Iceberg furrows occur at the seabed and are up to 5 m deep. On the basis of the distribution and stratigraphic relationships of the surficial sediments, it is suggested that above a 110 m depth the iceberg furrows were formed during the last 10,000-12,000 years and that these furrows may represent the total number developed during this time interval.
