AbstractCoastal energy infrastructure and other port projects require dredging to make the sites suitable for construction. On the west coast of Canada, dredging has been required at many recently proposed port sites. Environment and Climate Change Canada (ECCC) licences disposal of material at several large disposal-at-sea (DoS) sites on the coast. Proponents may also propose a new or temporary DoS site nearer to their development to save enormous shipping time and costs. Depending on the level of contamination of the sediment to be disposed, and the methods used, the regulation may require sediment to be disposed at either a dispersive or non-dispersive site. In the past several years, 'guidelines for determining dispersivity' have been proposed by NRCan (Lintern)/EC scientists and stipulated to two proponents. The validity of the methodology is being tested. NRCan is part of a triparty Regional Ocean Disposal Advisory Committee that will investigate several aspects of dredge disposal on the coast, one of which is dispersivity of existing sites. NRCan is tasked with determining dispersivity at existing sites and with conducting sensitivity analysis of the variables used in the existing guidelines. This requires oceanographic mooring instrumentation, data analysis and modeling.
Summary(Plain Language Summary, not published)
This is the fifth year for the project leaders of the Environmental Geoscience Program (EGP) from the Geological Survey of Canada (GSC) within Natural Resources Canada to present their annual scientific updates. Twelve power point presentations illustrate all the project status of all research going on within EGP. Subjects are connected to the following key words: Volcanoes, mercury, dredge disposal at sea, oil spills, diluted bitumen, oil sands, aquifer impacts, induced seismicity, geological storage of carbon, cobalt, climate change, Mackenzie River Basin, permafrost thaw, permafrost geochemistry, and cumulative effects.
