The Stanley Park Winter Waterbird Survey, 1995-2019, was made possible through a co-operative effort between Environment and Climate Change Canada, the British Columbia Institute of Technology’s Wildlife and Recreation Program, and the Stanley Park Ecology Society. The intent of the survey is to...

The Pulp & Paper Effluent Regulations (PPER) were published in 1992 pursuant to the Fisheries Act to control effluent discharges and reduce the impacts of effluents on fish and fish habitat that had been observed at pulp and paper mills across Canada at that time. The Regulations set out...

One of the ways of obtaining local-scale climate change scenarios is to use regression-based statistical downscaling of GCMs. In this approach, an empirical relationship between GCM predictors (i.e., near-surface and upper-level atmosphere circulation variables) and surface predictands (such as...

This notice applied to owners of facilities that manufactured synthetic rubber using acrylonitrile which resulted in releases of acrylonitrile to the environment. This notice was in effect from May 24, 2003, to May 31, 2007, for facilities involved in the manufacture of synthetic rubber. It is...

Pesticides surveillance data in freshwater from federal and federal-provincial sites at various locations throughout Canada are included in this dataset. Measurements mostly include pesticides but could include physical-chemical parameters such as temperature, pH, alkalinity, major ions,...

Acute and chronic toxicity and modes of action of benzotriazoles (BZTs) and benzotriazoles UV-stabilizers (BZT-UVs) were evaluated in freshwater invertebrates, algae, and fish. Gene transcription, life history (viability, growth, reproduction), and protein activities were measured after short and...

The toxicity of pharmaceuticals finasteride (FIN) and melengestrol acetate (MGA) was assessed in chronic (42 days) sediment tests with the amphipod Hyalella azteca. Two tests were completed for each compound. Survival, growth, reproduction and sex ratio were assessed at the end of each test.

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...

Ambient air is sampled daily, with a nominal 24-hour sampling period, on a Canadian Air and Precipitation Monitoring Network (CAPMoN) sequential sample head located 10 meters above ground. Air is drawn through a three-stage filter pack consisting of 47-millimeter Teflon, nylon and cellulose...

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...

At offshore sites, triplicate Ponar grabs (0.052 m-2) of sediment were collected from the M/V Namao. At nearshore sites, sediment samples were collected from a smaller workboat using a Petite Ponar grab (0.023 m-2) at the 3 m depth contour. Total sampling effort varied across the three years...

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...

This dataset is part of the International Atomic Energy Agency (IAEA) Global Network of Isotopes in Precipitation (GNIP) project and contains the total monthly precipitation quantity in millimeters collected on the roof of the National Hydrology Research Centre in Saskatoon, SK and its stable...

Long-term freshwater quality monitoring data for over 13 sites in the Columbia River Basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC)...

Long-term freshwater quality monitoring data for over 10 sites in the Arctic Coast - Islands Basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change...

Water quality and ecosystem health data used to conduct a cumulative effects assessment of Lake Superior nearshore waters in support of the Great Lakes Water Quality Agreement are included in this dataset. Data related to nearshore stressors is integrated into an overall assessment in a...

Water quality and ecosystem health data used to conduct a cumulative effects assessment of Lake Erie, St. Clair River, Lake St. Clair and Detroit River nearshore waters in support of the Great Lakes Water Quality Agreement are included in this dataset. Data related to nearshore stressors is...

Water quality and ecosystem health data used to conduct a cumulative effects assessment of Lake Ontario, Niagara River and St. Lawrence River nearshore waters in support of the Great Lakes Water Quality Agreement are included in this dataset. Data related to nearshore stressors is integrated into...
