We conducted a species-specific survey for Common Nighthawk (Chordeiles minor) near the northwestern limit of the species’ breeding distribution, in order to investigate relative abundance and also to determine whether a species-specific survey protocol being established for Canada would be...

We documented seasonal and daily activity patterns of Common Nighthawk (Chordeiles minor) near Whitehorse, Yukon, to evaluate the appropriateness at higher latitudes of national survey protocols for this species. Nighthawk vocalizations and audible aerial displays were detected at four locations...

Historical water quality data measured on a continuous basis at over 23 locations across Canada is included in this dataset. Most locations include hourly temperature, dissolved oxygen, pH, specific conductance and turbidity. Data are collected by Environment and Climate Change Canada (ECCC) and...

We studied the community structure of crustacean zooplankton along the biogeographical zones of the St. Lawrence River (Québec, Canada), to evaluate how the riverscale hydrological network formed by water masses, and local-scale aquatic environment, influenced the distribution of zooplankton...

We monitored a colony of Cliff Swallows (Petrochelidon pyrrhonota) nesting on an artificial nesting structure that had been built for this species, near the Dezadeash River in Haines Junction, Yukon (60o 44’ 58” N/ 137o 30’ 33” W). We took photographs of the nesting surface of each of the 16...

We synthesized 19 years of Sage Thrasher occurrence and related habitat data across the species' northern range in British Columbia (BC) and Washington (WA) to define critical habitat characteristics. We combined this field-derived (local-scale) data with GIS-derived (landscape-scale) data into...

This project is part of the Northern Contaminants Program core monitoring and looks at contaminant levels in landlocked Arctic char from lakes in Nunavut over time. Landlocked char are the only top predators in most Canadian high Arctic lakes and, therefore, can serve as a sentinel species for...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Reductions in phosphorus loads to Lake Winnipeg indicator shows the estimated extent to which projects funded by the Lake...

This dataset contains 21 statistics of wind and waves calculated from hourly reanalysis data of historical surface winds and ocean surface waves for the Canadian East Coast for the period 1954-2018 (each statistic has an annual, 4 seasonal, and 12 monthly values). These data can be used for...

The Joint Canada-Alberta Implementation Plan for Oil Sands Monitoring (Environment Canada and Alberta Environment 2012) included the initiation of new biomonitoring sites on the Lower Athabasca River mainstem and its major tributaries following the study designs proposed in the Integrated...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Solid waste diversion and disposal indicators report on the total quantity and the quantity per person of non-hazardous...

The Wastewater Systems Effluent Regulations (WSER), developed under the Fisheries Act, came into force in 2012 to manage wastewater releases by systems that collect an average daily influent volume of 100 cubic metres or more. The WSER also does not apply to any wastewater system located in the...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The indicator provides an overview of Canada's projected greenhouse gas (GHG) emissions up to 2035. The indicator allows the...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Municipal wastewater treatment indicator measures the level of wastewater treatment provided to the Canadian population....

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The phosphorus loading to lake Erie indicator reports on the total phosphorus loads flowing directly into Lake Erie or from...

Two precipitation measurement super-sites were established in Saskatchewan in anticipation of the World Meteorological Organization (WMO) intercomparison initiatives for automated in-situ measurement of solid precipitation and snow (2013-2015) and to provide infrastructure support for exploring...

Examining the short- and long-term toxicity effects (survival, behaviour and egg production) of Bisphenol A (BPA) and its replacement products (BPS, BPF, BPAF) on the embryo, juvenile and adult life stages of the Ramshorn snail (Planorbella pilsbryi) in 96-hour/7-day/13-day...

This river ice and river icing (aufeis) thickness, composition and hydrostatic water level data was collected over April 2 and 3, 2012 on the Muskeg, Ells and Firebag River in Alberta, Canada.

Tributary Biomonitoring (Lower Athabasca River) Benthic macroinvertebrates, comprising insects, crusteaceans, molluscs and worms, represent a group of organisms used widely in environmental monitoring programs as early warning indicators to assess the effects of change in water quality...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Changes in the status of wildlife species at risk indicator reports on changes in wildlife species designations for...
