AbstractAnalysis of existing data reveals that several marine geological hazards in Baffin Bay pose a potential threat to coastal communities, the environment and infrastructure in the area. Since 2011, the Geological Survey of Canada (GSC) has actively undertaken research on this issue. In August and September 2013, the GSC conducted an expedition to the area to investigate marine geological hazards. Preliminary results of this research are provided. A range of geological and geophysical data was collected during the expedition in order to develop a geological framework for the area and to characterize geological hazards. Data collected during the expedition will be used to assess seafloor stability, sediment transport, the recurrence of large earthquakes, the recurrence of seabed failure and the characterization of natural hydrocarbon seeps. This information will be provided to northern communities, the Government of Nunavut and regulators in order to better manage these
offshore areas.
Summary(Plain Language Summary, not published)
It is possible that several geological hazards in Baffin Bay may pose a threat to coastal communities, the environment, and infrastructure in the area. Since 2011, the Geological Survey of Canada (GSC) has actively undertaken research on this issue. In August and September 2013, the GSC conducted an expedition to the area to investigate marine geological hazards. Preliminary results of this research are provided. A range of geological and geophysical data was collected during the expedition. These data will be used to assess the stability of the seafloor, determine how often large earthquakes occur, determine how often large landslides occur on the seabed, and improve understanding of natural hydrocarbon seeps. This information will be provided to northern communities, the Government of Nunavut, and regulators in order to better manage these offshore areas.
