Lake Winnipeg, located in Manitoba, is approximately 25,000 square kilometers and is the tenth largest freshwater lake in the world. The mean depth is approximately 12 m. Lake Winnipeg's water shed encompasses 4 provinces, 4 states and over 100 Indigenous Nations. Economic benefits include a $110...

Off shore waters of Georgian Bay rarely experience excessive nutrient concentrations however, small embayments such as Honey Harbour, North and South Bay have experienced oxygen depletion, increased total phosphorus, a decrease in water clarity and the presence of filamentous attached algae. Low...

Blooms of filamentous benthic algae that plagued Lake Erie in the 1950s through 1970s were largely reduced through reductions of phosphorus (P) loading from point sources. Since the mid-1990s, these blooms have returned despite a period of relatively stable external P inputs. While increased...

Categorization was required by the Canadian Environmental Protection Act, 1999 (CEPA 1999) and is a first step to finding out which of these chemical substances require further attention in the form of assessment, research and/or measures to control their use or release. This task was completed...

Archived population trend estimates, based on data collected through the North American Breeding Bird Survey (BBS), for approximately 300 Canadian bird species. These archived estimates use data from Canadian BBS routes only, collected from 1970 through 2011. Trends are presented for species,...

Azo dyes are synthetic compounds used as industrial colorants, and some are predicted to be inherently toxic, bioaccumulative, and/or persistent based upon their chemical composition. This study addressed data gaps in current research which included the need to evaluate the toxicity of...

Bay of Quinte was designated as one of the 43 Areas of Concern in accordance with Great Lakes Water Quality Agreement (GLWQA). Remedial Action Plan (RAP) is an ongoing collaborative effort implemented by federal, provincial, and local governments as well as industry and public partners. There are...

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 4 site locations (Trenton, Deseronto, Belleville, Prince Edward Bay) within the Bay of Quinte Area of Concern. Halogenated Phenolic Compounds have...

Thunder Bay was designated as one of the 43 Areas of Concern in accordance with Great Lakes Water Quality Agreement (GLWQA). Remedial Action Plan (RAP) is an ongoing collaborative effort implemented by federal, provincial, and local governments as well as industry and public partners. There are 3...

The river bed sediments in the Lower Athabasca are known to shift and migrate downstream. Numerical modelling of water quantity and quality (including sediments) requires accurate river channel cross-sectional geometry within the area of study. Such cross-sectional geometry prior to 2012 was...

The Niagara River was designated as one of the 43 Areas of Concern in accordance with Great Lakes Water Quality Agreement (GLWQA). Remedial Action Plan (RAP) is an ongoing collaborative effort implemented by federal, provincial, and local governments as well as industry and public partners. There...

Wild fish health data (length, weight, gonad size, etc.) are now available for trout perch collected from the Athabasca and Peace Rivers; white sucker collected from the Athabasca River; longnose sucker collected from the Peace River; slimy sculpin collected from the Steepbank River; lake chub...

Sediment from Lakes Polycyclic aromatic hydrocarbons (PAHs), 47 elements including numerous metals, and visible reflectance spectroscopy or VRS-chla have been determined in sediment core samples collected in 2012, 2013 and 2014 from 16 small (surface area 4-97 ha; maximum depth ~1-5 m deep),...

The atmospheric monitoring subcomponent of the Northern Contaminants Program (NCP) studies long-range transport of anthropogenic organic pollutants in air (AOPA), mercury, and chemicals of emerging arctic concern from around the globe. This subcomponent includes three NCP Core Monitoring...

Precipitation samples are collected at a number of sites in Alberta by Alberta Environment and Parks. Samples are analyzed for select cations and anions as well as pH. Samples are collected weekly using an event-only precipitation sampling protocol. The specific monitoring objectives are to: (1)...

Substituted diphenylamine antioxidants (SDPAs) and benzotriazole UV stabilizers (BZT-UVs) are additives used in industrial and consumer products to prevent degradation or colour change of materials, but their environmental fate and disposition are not well characterized. In this study, SDPAs and...

Concentrations of alternative flame retardants and polybrominated diphenyl ethers (PBDEs) were analyzed in ringed seal (Phoca hispida) blubber collected across the Canadian Arctic during subsistence hunts between 1998 and 2013. The presence of flame retardants in ringed seals suggests their...

As part of a three year study funded by Environment and Climate Change Canada and Natural Resources Canada (ecoENERGY Innovation Initiative, project UOSGQ963; http://www.nrcan.gc.ca/energy/funding/current-fundingprograms/eii/4985) data were gathered to assess and monitor water quality conditions...
