The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Temperature change in Canada indicator shows the yearly and seasonal surface air temperature departures for the years...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Snow cover indicator shows how Canada's snow cover is changing from year-to-year and over time. Snow cover extent is...

The Turkey Lakes Watershed (TLW) Study was initiated in 1980 by Environment Canada, Natural Resources Canada and Fisheries and Oceans Canada to evaluate anthropogenic perturbation of Canadian Shield ecosystems. Originally, the Study focused on the aquatic and terrestrial effects of acid rain, but...

This dataset contains temperature data taken from 11 streams or rivers in Forillon National Park since 2008. Temperature data are collected hourly by a HOBO probe installed on the watercourse’s bottom in June and removed in September or October. For each watercourse studied, the temperature probe...

The Elk Island National Park monitors the lake water quality annually in two lakes by measuring parameters such as: nutrients, heavy metals, major ions, physical characteristics, and pollutants/contaminants.

Terra Nova National Park uses fixed station stream gauges and pressure temperature loggers to monitor the following stream flow aspects: Richards-Baker index of flashiness, ratio of yearly precipitation to runoff, low flow volume, annual maxima/minima, and mean monthly flow.

Water temperature is considered a key ecosystem driver in freshwater ponds and streams of PEI National Park. American eel and Eastern Brook trout have been chosen for evaluating pond and stream temperature conditions as they are a common residents in most Atlantic Canada water bodies. Eastern...

PEI National Park samples Chlorophyll-a to measure aquatic productivity in four freshwater ponds. The sampling is carried out on an hourly basis between May-October each year using YSI sonde data loggers. In PEINP, all freshwater ponds are shallow (maximum depth is 4.5 m) and non-stratifying....

The Turkey Lakes Watershed (TLW) is 1 of 5 hydrologically "calibrated" basins in eastern Canada that were originally devoted to process-oriented research into "acid rain" effects. They were selected to cover a wide range of climatic and hydrological conditions, deposition magnitudes, and terrain...

Groundwater wells were installed in the Turkey Lakes Watershed basin in the early 1980’s. These test wells were installed in eight sub-basins of the watershed and range in depth from 0.5 to 9.7 metres. They are located on a variety of terrain throughout. The water chemistry has been sampled at...
