Environment Canada , legally incorporated as the Department of the Environment under the Department of the Environment Act , is the department of the Government of Canada with responsibility for coordinating environmental policies and programs as well as preserving and enhancing the natural environment and renewable resources. The powers, duties and functions of the Minister of the Environment extend to and include matters relating to: "preserve and enhance the quality of the natural environment, including water, air, soil, flora and fauna; conserve Canada's renewable resources; conserve and protect Canada's water resources;forecast daily weather conditions and warnings, and provide detailed meteorological information to all of Canada; enforce rules relating to boundary waters; and coordinate environmental policies and programs for the federal government."Its ministerial headquarters is located in les Terrasses de la Chaudière, Gatineau, Quebec.Under the Canadian Environmental Protection Act , Environment Canada became the lead federal department to ensure the cleanup of hazardous waste and oil spills for which the government is responsible, and to provide technical assistance to other jurisdictions and the private sector as required. The department is also responsible for international environmental issues . CEPA was the central piece of Canada's environmental legislation but was replaced when budget implementation bill entered into effect in June 2012.Under the Constitution of Canada, responsibility for environmental management in Canada is a shared responsibility between the federal government and provincial/territorial governments. For example, provincial governments have primary authority for resource management including permitting industrial waste discharges . The federal government is responsible for the management of toxic substances in the country . Environment Canada provides stewardship of the Environmental Choice Program, which provides consumers with an eco-labelling for products manufactured within Canada or services that meet international label standards of Global Ecolabelling Network.Environment Canada continues to undergo a structural transformation to centralize authority and decision-making, and to standardize policy implementation.

Frank Dempsey suggests that various remote-sensing, analysis, and forecasting methods allow anticipation of the harmful increases in airborne fine particulates and ozone pollution caused by the plumes of distant fires. The recognition and forecasting of trajectories of smoke plumes from active fire will be beneficial for anticipating and predicting potential effects on air quality in eastern North America. A case highlights a case where distinct increases in concentrations of fine particles and O3closely correlated with the plume from a distant wildfire, have been observed in routinely collected air quality observations in Ontario's air monitoring network. The specific data that indicate detection of smoke from northern sources are the air quality observations from various locations in southern Ontario. Several more examples have also been presented to demonstrate the benefits of recognition and forecasting of trajectories of smoke plumes in anticipating and predicting potential effects on air quality.

The analysis of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, polychlorinated biphenyls, and other related compounds requires complex sample preparation and analytical procedures using highly sensitive and selective stateof-the-art instrumentation to meet very stringent data quality objectives. The analytical procedures (extraction, sample preparation), instrumentation (chromatographic separation and detection by mass spectrometry) and screening techniques for the determination of dioxins, furans, dioxin-like polychlorinated biphenyls and related compounds with a focus on new approaches and alternate techniques to standard regulatory methods are reviewed. © 2009 Wiley Periodicals, Inc.,.

Climate Dynamics

Decadal prediction of the coupled climate system is potentially possible given enough information and knowledge. Predictability will reside in both externally forced and in long timescale internally generated variability. The "potential predictability" investigated here is characterized by the fraction of the total variability accounted for by these two components in the presence of short-timescale unpredictable "noise" variability. Potential predictability is not a classical measure of predictability nor a measure of forecast skill but it does identify regions where long timescale variability is an appreciable fraction of the total and hence where prediction on these scale may be possible. A multi-model estimate of the potential predictability variance fraction (ppvf) as it evolves through the first part of the twenty-first century is obtained using simulation data from the CMIP3 archive. Two estimates of potential predictability are used which depend on the treatment of the forced component. The multi-decadal estimate considers the magnitude of the forced component as the change from the beginning of the century and so becomes largely a measure of climate change as the century progresses. The next-decade estimate considers the change in the forced component from the past decade and so is more pertinent to an actual forecast for the next decade. Long timescale internally generated variability provides additional potential predictability beyond that of the forced component. The ppvf may be expressed in terms of a signal-to-noise ratio and takes on values between 0 and 1. The largest values of the ppvf for temperature are found over tropical and mid-latitude oceans, with the exception of the equatorial Pacific, and some but not all tropical land areas. Overall the potential predictability for temperature generally declines with latitude and is relatively low over mid- to high-latitude land. Potential predictability for precipitation is generally low and due almost entirely to the forced component and then mainly at high latitudes. To the extent that the multi-model ppvf reflects both the behaviour of the actual climate system and the possibility of decadal prediction, the results give some indication as to where and to what extent decadal forecasts might be possible. © 2010 Her Majesty the Queen in Right of Canada.

Skimmers, barges and related methods recover heavy oil or bitumen from contaminated water environments such as tailings ponds. The skimmer has an articulated mesh-like conveyor driven around a drum by a drive sprocket. A pusher mechanism discharges bitumen or heavy oil from cavities in the conveyor. In one embodiment, the skimmer includes an automatic depth control system. In other embodiments, knife-edged shear plates remove heavy oil or bitumen adhering to the conveyor and drum. A barge may incorporate multiple parallel skimmers. The barge may include a bitumen-transfer pump having an annular fluid-injection flange that generates an annulus of lubricating fluid inside a discharge hose. A method of skimming heavy oil or bitumen involves using a skimmer that automatically adjusts its elevation or depth based on a control signal generated by a depth sensor. Another method recovers and transfers bitumen by lubricating the discharge hose using the annular fluid-injection flange.
