| Summary | (Plain Language Summary, not published)
In 2009 the GSC initiated a research project to study marine geohazards in the Canadian Beaufort Sea. The primary driver for the project was the oil and
gas industry's interest in exploration in water depths up to 1500 m. Submarine slope instability represent one of the major potential geohazards. Assessment of slope instability requires measurement and evaluation of geotechnical properties of the
marine sediments. A comprehensive geotechnical laboratory test program was carried out on 23 piston and gravity cores collected between 2009 and 2016. Geotechnical testing included MSCL bulk density, Atterberg limits, grain size, consolidation tests
triaxial tests. This open file presents the geotechnical testing methodology and geotechnical results. It provides geotechnical profiles, high-resolution seismic data over most core sites and a preliminary infinite slope analysis of the Beaufort Sea
surficial slope sediments. |
