The bloody red shrimp (Hemimysis anomala) has invaded all of the Great Lakes except for Lake Superior. Sampling shows the highest numbers in Canadian waters are in the Port of Montréal. Given its high level of activity, the port could represent a key ...
A recent workshop, Dispersant Use in the Canadian Beaufort Sea, held in Inuvik (Northwest Territories), provided major stakeholders with an understanding of chemical oil spill dispersants and considered the environmental effects and benefits of using dispersants to respond to oil spills ...
Dr. Tom Edge and Stephen Hill have been awarded a Scientific and Technical Achievement Award from the United States Environmental Protection Agency for their recent research publications on microbial source tracking. Environment Canada and United States Environmental Protection Agency researchers applied genomics techniques to discover ...
Work completed in collaboration with scientists from McMaster, Guelph, and Ryerson universities has led Dr. Ian G. Droppo to conclude that river bed sediment can represent a significant source of pathogenic organisms to the water column ...
Environment Canada scientists have discovered that populations of Round Goby (Neogobius melanostomus) recently introduced in the St. Lawrence River were considerably less parasitized than two indigenous fish species, whereas the Round Goby is highly infected with parasites in its native range...
Improved Processes and Parameterization for Prediction in Cold Regions (2006–2011) is a research network devoted to improving understanding of cold regions hydrometeorology ...
Algae and Omega-3 Polyunsaturated Fatty Acids: A Double Edged Sword? Implications for Fisheries, Foodwebs, and Foul Odours
... focused on compounds produced largely by golden algae, and showed that they can have significant and sometimes insidious socioeconomic and ecological impacts at several foodweb levels, and potentially affect recruitment success of commercially important fish species such as salmon ...
Release of State of Lake Winnipeg: 1999 to 2007 Report
Environment Canada and Manitoba Water Stewardship have released the State of Lake Winnipeg report, the first comprehensive assessment of the physical, chemical and biological characteristics of Lake Winnipeg since intensive monitoring began in the late 1990s. The report documents research and monitoring on Lake Winnipeg’s water quality, water levels, algae growth, climate conditions, and emerging issues, and will serve as an important reference to measure progress to restore the health of Lake Winnipeg.
The report, a deliverable under EC's Lake Winnipeg Basin Initiative, is a collaboration by researchers from government, universities and non-governmental organizations. Lucie Levesque, Malcolm Conly and John Lawrence led EC’s efforts. Technical and highlights reports are available in CD format or online from either EC's Publication Catalogue or Manitoba Water Stewardship. CD and printed copies are also available from Nancy Hnatiuk at the Lake Winnipeg Basin Office (204-983-4819; Nancy.Hnatiuk@ec.gc.ca).
Physical Processes in Natural Waters
A conference proceedings of the 15th International Workshop on Physical Processes in Natural Waters, held In July in Burlington is now available. Environment Canada, in collaboration with the University of Guelph, organized the meeting, which focused on physical processes and the linkages to ecosystem processes and water quality in lakes. Water and atmospheric scientists presented recent work on management of taste and odour problems in drinking water; dispersion of wastewater in lakes; algal bloom development; sustainable aquaculture; the impact of river plumes on nearshore water quality and attached algae in the nearshore environment; and impacts of extreme climate conditions and episodic events in the lakes. Selected presentations will be published as a special issue of the Water Quality Research Journal of Canada.
Temporal Comparison of Benthic Conditions within Two Areas of Concern
Two new publications are available that compare benthic conditions in 2009 with those from 2003 in two Areas of Concern and are available in PDF from Danielle Milani, (Danielle.Milani@ec.gc.ca, 905-336-4760) of Aquatic Ecosystem Impacts Research:
