AbstractIntegrated seabed mapping is an important prerequisite for effective management of offshore areas. With the rapidly expanding City of Iqaluit on its shores and mineral resources on nearby Hall Peninsula, Frobisher Bay will undoubtedly see new infrastructure development over the next several years. The 2014 field season marked the first of a two-year, collaborative, seabed-mapping project in the region. The purpose of the project is to improve understanding of the geology of Frobisher Bay and, ultimately, to support decision-making with respect to its seabed use. Using both legacy and newly acquired high-resolution seabed-morphology and geology data, the project will generate a suite of bathymetric and geological maps for the floor of Frobisher Bay. Initial results reveal three zones (outer, middle and inner) with distinctive seabed morphology and surficial geology, and extensive evidence of seabed-slope instability in the inner zone.
Summary(Plain Language Summary, not published)
Information about the shape and geology of the seabed is important for managing offshore areas. Frobisher Bay is an important seaway for the transportation of goods to and from Iqaluit. Iqaluit is rapidly expanding and there are a number of natural resource projects proposed for the region, so it is likely that Frobisher Bay will see new developments along its coast and in the bay itself over the next several years. These developments could include expanded port facilities and the installation of fibre optic cables on the seabed. A seabed mapping project has begun in the region involving partners from the Territorial and Federal governments, and universities. The purpose of the project is to improve understanding of the geology of Frobisher Bay and ultimately to support decision-making with respect to its seabed use. Using data acquired over the last 40 years, and newly-acquired bathymetry and geology data, the project will produce a new set of maps for the shape and geology of the floor of Frobisher Bay.
