| Summary | (Plain Language Summary, not published)
A predominantly coastal population and competing demands for seabed usage have driven the need to understand marine geohazards in Baffin Bay. One of the
primary geohazards include seabed stability impacting coastal communities affected by seabed failure induced tsunamis and seafloor infrastructures, such as communication cables. Since 2012, a GSCA research project has been underway to create a
predictive geohazard framework offshore Baffin Island. Part of this study included the regional geotechnical characterization of seabed sediment. A comprehensive geotechnical testing program was undertaken at GSCA to classify and the determine
geotechnical properties of sediments from 5 piston cores collected in 2013 on board CCGS Hudson. This characterization provides the framework to understand and predict the behaviour of these sediments as potential geohazards. |
