| Résumé | (disponible en anglais seulement)
Since 1962, scientists at Bedford Institute of Oceanography have mapped large stretches of coastline, and increased our understanding of the wide diversity of
Arctic and Atlantic coastal systems in Canada. Areas investigated range from the macrotidal Bay of Fundy to the microtidal, sandy barrier, and dune systems of the Gulf of St. Lawrence; from the paraglacial gravel barriers of the submergent Atlantic
coast, and the gravel-dominated emergent coasts of the central Canadian Arctic Archipelago to the ice-bound coasts of the northwestern Archipelago; and the higher-energy, transgressive coast of the Beaufort Sea with its ice-rich tundra cliffs and the
second largest delta on the Arctic Ocean. A coastal systems approach including aerial imagery of more than 20,000 km of coastline has led to greater understanding of integrated shore-zone, shoreface, and inner-shelf processes based on innovative
approaches and technology for data acquisition in challenging nearshore and ice-congested waters. Monitoring was initiated at 613 sites, nearly half on Arctic shores, with 67 of these surveyed repetitively over more than 20 years. These data have
provided a baseline reference for analysing the risk of flooding and shoreline change in coastal communities, assessing environmental impacts of developments in the coastal zone, and predicting the potential impacts of climate change and accelerated
sea-level rise. Today, with high-resolution satellite imagery and other advanced technology, larger areas of coastline can be examined remotely with suitable resolution. Nevertheless, a requirement remains for field investigations to provide an
understanding of complex coastal environments, and to respond to societal needs. |
