Knowledge of shallow-water bathymetry is crucial for safe marine shipping and infrastructure development, but most of Nunavut’s shallow waters remain poorly surveyed. Satellite-derived bathymetry (SDB) is a potentially cost-effective technology for surveying these areas. To assess the large-scale potential for SDB in Nunavut, the proposed research will:
1) Test existing SDB methods for shallow waters surrounding the seven largest coastal communities in Nunavut.
2) Produce up-to-date maps of water depth for the optically shallow sections of those areas.
3) Identify areas where existing nautical charts and SDB do not agree.
The project will be carried out by Dr. Anders Knudby and Kiyomi Holman from the University of Ottawa. Field measurements of seafloor colour and water depth will be collected in shallow-water areas around Cambridge Bay at the beginning of August 2017. In combination with satellite imagery, these data will be used to test SDB methods over the following year. SDB methods will be developed and tested in Cambridge Bay, which has clear water and large shallow areas and therefore provides an ideal test environment. The best methods will then be applied and further tested in areas near Iqaluit, Igloolik, Rankin Inlet, Arviat, Pond Inlet, and Kugluktuk.
