"This report presents the surficial geology of the Scotian Shelf Bioregion (SSB). The Scotian Shelf surficial geology had been interpreted in the past over the shallower portions of the bioregion as well as on the slope. Since these early maps were produced, more recent and higher resolution hydroacoustic data have been acquired. Therefore, the main objective of the present study is to update the existing surficial geology over the entire SSB, both shelf and slope, using new available maps and data sets. This report constitutes a review of all existing publically available data sets and associated studies that provide information on surficial geology within the bioregion and describes how previous maps and recent data were amalgamated to produced a new updated version of the surficial geology within the SSB"--Introduction, page 4.
