The recent (2017) spatial patterns of zooplankton communities in 73 Québec lakes distributed over an 800-km SW-NE gradient, spanning a wide range of water quality and climate. Results were published in a scientific article that can be found here: https://doi.org/10.1139/cjfas-2020-0139

The toxicity of pharmaceuticals finasteride (FIN) and melengestrol acetate (MGA) was assessed in freshwater mussels, including an acute (48 h) aqueous tests with glochidia from Lampsilis siliquoidea, a sub-chronic (14 days) sediment test with gravid female Lampsilis fasciola, and chronic (21 and...

This dataset includes historical observations of the daily depth of snow on the ground (daily climate element 013) made at Environment and Climate Change Canada (ECCC) sites by manual ruler or by a sonic sensor equipped autostations. The history of the ECCC daily snow depth observing program is...

Jackfish Bay was identified as an Area of Concern (AOC) in 1987 due to degraded water and sediment quality and environmental health, which included impairment to benthic communities. As part of the Great Lakes Action Plan, assessments of benthic conditions in the Jackfish Bay AOC have been...

The EXCEL workbooks contained in this dataset primarily contain temporal variations of the water surface elevation (water level) at 12 locations situated along the lower Athabasca River during the 2013 spring ice breakup. This information was obtained using portable pressure (and occasionally...

The Orbiting Carbon Observatory 2 (OCO-2) is a National Aeronautics and Space Administration (NASA) satellite launched in 2014. Although OCO-2 was not designed for monitoring power plant emissions, in some cases, carbon dioxide (CO2) observations from OCO-2 can be used to quantify daily CO2...

This dataset consists of CLASS (Canadian Land Surface Scheme) simulations for ALMIP2 (AMMA [African Monsoon Multidisciplinary Analysis] Land Surface Model Intercomparison Project, Phase 2). The results of the intercomparison is published in the paper "Streamflows over a West African Basin from...

Environment and Climate Change Canada's (ECCC’s) air quality model, Global Environmental Multiscale – Model of Atmospheric Chemistry (GEM-MACH v2), was run at high spatial resolution to generate daily forecasts for the Air Quality Health Index (AQHI) at Pan Am sporting venue locations and for...

Population trend estimates based on data collected through the North American Breeding Bird Survey (BBS), for approximately 300 Canadian bird species. The trend results are Canadian trends and thus use data from Canadian BBS routes only. Results are updated annually; these estimates use BBS data...

Sidney Island Shorebird Surveys transects area feature.

Survey points is a point feature class containing transects and observations completed in 2011.

Restrictions in the utilization of polybrominated diphenyl ether (PBDE) mixtures have led to the increased usage of alternative flame retardant additives in a wide range of commercial applications. The present study examined the occurrence of established and emerging flame retardants (EFRs) in...

Neonicotinoids are the most widely used insecticides in the world. They are preferentially toxic to insects while displaying a low toxicity toward vertebrates, and this selective toxicity has resulted in the rapid and ubiquitous use of these compounds. However, neonicotinoids have been detected...

This dataset contains the fish health metrics (length, weight, gonad size, etc.) for Brown bullhead (Ameiurus nebulosus) and Yellow Perch (Perca flavescens) collected from three site locations (Queenston, Point Abino, and Black Creek) within the Niagara River Area of Concern for 2004 and 2008....

Freshwater mussels contribute important ecological functions to aquatic systems. The water filtered by mussel assemblages can improve water quality, and the mixing of sediments by burrowing mussels can improve oxygen content and release nutrients. However, nearly 70 percent of North American...

The study examines the parasite communities in Athabasca River Trout-perch (Percopsis omiscomaycus) at five sites along the main stem of the Athabasca River to explore whether any observed changes in parasite abundance or community structure might correlate with small-scale variations in water...

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 3 site locations (Frenchman's Bay, Tommy Thompson, and Toronto Island) within the Toronto and Region Area of Concern. Halogenated Phenolic Compounds...

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 2 site locations (Wheatley Harbour, and Hillman Marsh) within the Wheatley Harbour Area of Concern. Halogenated Phenolic Compounds have emerged as an...

This dataset contains the fish health metrics (length, weight, gonad size, etc.) for Brown bullhead (Ameiurus nebulosus) collected from three site locations (Frenchman's Bay, Toronto Island and Tommy Thompson) within the Toronto and Region Area of Concern for 2003 and 2006. Supplemental...

The Richelieu River, Quebec, is a highly-regulated waterway subject to numerous anthropogenic influences from municipal effluents and agricultural activities. Parasite communities in 234 spottail shiners (Notropis hudsonius) were examined from 4 localities in late spring 2003 and 2004. Parasite...
