Project: Geology Research in Baffin Bay : REDUCING RISK TO COASTAL COMMUNITIES AND OFFSHORE INFRASTRUCTURES CAUSED BY MARINE GEOHAZARDS AND SEISMICITYAlexandre Normandeau, Natural Resources Canada The proposed expedition would take place in August or September 2022, depending on vessel availability. The expedition is part of the Geological Hazards in Baffin Bay Activity within the Public Safety Geoscience (PSG) Program of the Geological Survey of Canada, which began in 2012, and is partly funded by NRCan, CIRNAC and ArcticNet. To date, the activity has resulted in research expeditions in 2013 (NPC 148842, NIRB 13YN021) and 2018 (NPC 148842, NIRB 13YN021) and in 2019 (NPC 149732), as well as community engagement meetings in 2013, 2014, 2015, 2016, and 2019. Information collected during this project will help support community and government decisions on use of offshore areas and provide communities with better knowledge for improving public safety. The proposed research expedition would take place in and around the community of Grise Fiord. The major goals of this proposed research for 2022 would be: -To investigate the stability of the seabed in fjords near Grise Fiord. New imagery of the seabed shows that submarine landslides have occurred in several locations. Baffin Bay experiences a number of earthquakes and iceberg groundings which can trigger submarine landslides. Our research will help to determine the risk for a large submarine landslide happening in the future. -Coring and mapping of coastal environments would allow us to collect evidence of past tsunamis affecting the shoreline, similar to the 2017 Greenland tsunami. In addition, digging in coastal areas may take place using shovels to observe if tsunamis have occurred in the past near the villages.During this type of expedition, we typically collect seabed sediment samples (2 m long gravity cores), seafloor photographs and video, information about the shape of the seabed, and sub-bottom imaging. These instruments will be the same as those used during the 2013, 2018 and 2019 expeditions. The research would take place onboard the Government of Nunavut vessel Nuliajuk. If this project is accepted, the research ship is available in August or September. Research results will be reported back during community visits after the conclusion of the field season or directly following the cruise and will be made publicly available. Results will also be presented at workshops in the North, at science conferences (ArcticNet) and will result in publications in various scientific journals, reports and plain language documents over the months and years following the project.
