Project Description: The objective of this research project is to continue the examination of coastal sediment exposures and drained lake basins for evidence for paleo-tsunamis deposits and investigate coastal erosion rates.

This year, the research team will be focusing on one task: A small, 2 kg (5 lb), electric powered Unmanned Aerial Vehicle (UAV) will be used to collect low-altitude (<90 m) aerial imagery at North Head. The purpose of this survey is to map permafrost and coastal features at North Head in high resolution 3D. One or two, small-foot print (<7 sq. km) surveys will be undertaken, each taking less than 4 hours to complete. These surveys will be conducted following Transport Canada’s Canadian Aviation Regulations (CARs), that ensure safe conditions exist at all times during the survey, including minimum distances from people and other potential hazards. The UAV operator will maintain visual contact with the UAV at all times during the surveys and a second “spotter” person will also be present. No disturbance to wildlife will take place (i.e. surveys will be not be commenced if wildlife are nearby and surveys will be terminated if wildlife are observed while the UAV is airborne).

The same area was surveyed in the summer of 2015 and the difference between the 2015 and 2016 coastlines derived from the two surveys will provide accurate estimates of coastal erosion rates and insight into the geomorphological conditions related to erosion.

Copies of all scientific contributions (scientific papers, maps, and databases) will be provided to the communities in the Inuvialuit Settlement Region through the Aurora Research Institute (ARI).

The fieldwork for this study will be conducted from August 24, 2016 to December 31, 2016.
