This project aims to develop a remote sensing based framework for Newfoundland and Labrador (NL) wetland inventory and classification and monitoring through the synergistic use of satellite and airborne multi-spectral and ortho-imagery and space-born synthetic aperture radar (SAR) data. The proposed project involves collaboration from C-CORE, Ducks Unlimited Canada, and Santec. The results and approach will help Ducks Unlimited Canada for conserving wetland and for waterfowl, wildlife and people.
Wave uprush and the potential for flooding are natural hazards that must be determined by the Cataraqui Region Conservation Authority (CRCA) prior to the approval of a near-shore development. The purpose of calculating wave uprush is to recommend building sites that are outside of the wave uprush area (and floodplain in general) to land owners and municipalities, as well as provide information for flood proofing of existing buildings, roadways, etc. The CRCA has manually calculated wave uprush at 200 sites along the more than 200 km of shoreline in eastern Lake Ontario and the St.
Pacific salmon play an important economic, ecological, and cultural role throughout their range. However, declining salmon populations have diminished this role in many regions. The factors responsible for declines are poorly understood but are of great interest, particularly for First Nations, who have a large role in salmon management.
In British Columbia, highly saline waste water produced as a by-product of oil and gas operations are injected into deep geological formations via injection wells. The purpose of this research project is to investigate whether or not these injected fluids remain at depth as intended or rather, can return to the surface and contaminate water resources. In particular this project aims to evaluate the role that surrounding active and abandoned wellbores play in acting as vertical conduits for subsurface fluids to leak to the surface.
Grizzly bears represent a valuable economic, ecological, cultural and symbolic resource for British Columbia. In order to preserve this resource the current population of brown bears needs to be monitored to ensure the health of the population. One marker of health is the genetic health of the population. Genetic monitoring can also tell us important information about how related different bear populations are and how well these populations are adapted to their ecosystem.
Atlantic Gold is preparing to start construction for an open pit mine near the city of Halifax, Nova Scotia. However, significant wetlands will have to be altered to complete this construction. The current policies regarding wetland alteration and compensation in Nova Scotia focus on area. For example, if 25 hectares of wetland are to be altered, it is required that Atlantic Gold will have to create 50 hectares of new wetland to compensate.
Rivers in much of eastern Canada flow through regions comprised of cohesive glacial sediments, including glaciomarine clays and glacial tills. Given the glacial history of Canada, many if not most of its rivers can be characterized as semi-alluvial.
Management of these rivers in terms of sediment load is a difficult challenge, because relatively little is known about their stable channel geometry.
Predicting the quantity of mineral (gold, coper, etc) or hydrocarbon (oil, gas) extracted from a given deposit is difficult. One concern is the uncertainty in the resources underground. A few initial wells or drill holes give us access to an estimate of the quantity of resource, but there is great uncertainty because sampling can be hundreds of meters or kilometers apart.
Sedimentary rock formations are currently under consideration for the placement and long-term storage of used nuclear fuel originating from nuclear power generation. A thorough understanding of the long-term geochemical stability in these rock formations is important to prove that future interactions of the waste material with aquifers as well as flora and fauna at the land surface can be ruled out for time periods exceeding 10,000 years.
Recirculating aquaculture systems are indoor, tank-based systems which allow aquaculturalists to raise fish in controlled environmental conditions through the use of several water treatment processes. Research related to the aquaculture industry is important, as it is currently one of the fastest growing food industries. This research aims to improve the operation of these systems by reducing the amount of organic waste in the recirculated water through the use of ozone.
