Abstract

This overall aim of the project was to develop a better understanding of the formerly
glaciated continental shelf focussing on on a large area of Newfoundland’s inner
southern shores from Bay de Espoir to Burgeo. The survey had three main scientific objectives which were as follows:

(i) To contribute to the topographic mapping of the Newfoundland Shelf and Atlantic Seabed, and to refine site selection for coring with the acquisition of new multibeam echosounder bathymetric data.

(ii) To determine the sub-seabed stratigraphy at target locations that were identified from published and legacy marine geophysical data and newly acquired data from through the acquisition of chirp and sparker seismic data. The seismic data will allow an optimal selection of coring sites based on stratigraphy and sub-bottom acoustic character.

(iii) To sample glacial deposits using vibro and gravity coring for sedimentological and geochronological analyses.
