Permafrost loss is pervasive across northern circumpolar regions. The loss of frozen ground has profound impacts on water resources at varying spatial and temporal scales via changes to predominant hydrological processes, runoff pathways and entrainment rates of solutes and sediments. Consensus...

This polygon outlines the basic area included in the survey counts. This area is the best approximation of the mudflat that can be surveyed from shore and is exposed at tide tide height of 3.5 m, based on tidal predictions at Point Atkinson, British Columbia.

Since 1988, the governments of Canada and Quebec have been working together to conserve, restore, protect and develop the St. Lawrence River under the St. Lawrence Action Plan (SLAP). One of the projects identified under the theme of biodiversity conservation is the development of an integrated...

Data Sources: Banque informatisée des oiseaux de mer au Québec (BIOMQ: ECCC-CWS Quebec Region) Atlantic Colonial Waterbird Database (ACWD: ECCC-CWS Atlantic Region).. Both the BIOMQ and ACWD contain records of individual colony counts, by species, for known colonies located in...

The bioaccumulation of a broad range of pharmaceuticals and personal care product chemicals (PPCPs) was studied in Cootes Paradise Marsh (CPM), an urban wetland that receives tertiary treated municipal waste waters as well as urban storm runoff. PPCPs were measured in caged and wild goldfish, 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...

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...

The Alberta foothills are a primary source of spring runoff into the prairie regions to the east. For this reason, precipitation accumulations in the foothills are vital to prairie water resources. The Foothills Orographic Precipitation Experiment (FOPEX) was initiated in 2002 to study the...

Venlafaxine is an antidepressant and anti-anxiety drug that has been detected in municipal wastewater at low concentrations. To assess the potential of this compound to affect the survival, development and reproductive capacity of fish, we exposed Fathead minnow (Pimephales promelas) over a full...

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...

The Canadian Breeding Bird Census (BBC) Database contains data for 928 breeding bird plot censuses representing all known censuses of breeding birds carried out in Canada during the period 1929–1993. The 928 records in the database represent 640 unique census plots located in all provinces and...

Canadian Wetlands Inventory (CWI) data for the Appalache region. Created according to the method developed by the Canadian Wildlife Service, Quebec Region. Between 2003 and 2007, the Canadian Wildlife Service, Quebec Region (CWS-QC) produced wetland maps for several sites in Quebec. This mapping...

Between 2003 and 2007, the Canadian Wildlife Service, Quebec Region (CWS-QC) produced wetland maps for several sites in Quebec. This...

Canadian Wetlands Inventory (CWI) data for the Grande plée Bleue region. Created according to the method developed by the Canadian Wildlife Service, Quebec Region. Between 2003 and 2007, the Canadian Wildlife Service, Quebec Region (CWS-QC) produced wetland maps for several sites in Quebec. This...

Canadian Wetlands Inventory (CWI) data for the Baie de l'Isle-Verte region. Created according to the method developed by the Canadian Wildlife Service, Quebec Region. Between 2003 and 2007, the Canadian Wildlife Service, Quebec Region (CWS-QC) produced wetland maps for several sites in Quebec....

With the aid of aerial photographs from 2006 and the stereoscopic principle, the wetlands of Montérégie were mapped in 2007 as part of a project of the Monteregie Geomatics Agency (GéoMont). The Canadian Wildlife Service had indicated that it needed more up-to-date maps of the wetlands in the...

Canadian Wetlands Inventory (CWI) data for the Radisson region. Created according to the method developed by the Canadian Wildlife Service, Quebec Region. Between 2003 and 2007, the Canadian Wildlife Service, Quebec Region (CWS-QC) produced wetland maps for several sites in Quebec. This mapping...

Land use classification on the basis of multidate Landsat-ETM and Radarsat-1 images. Classification is based on the segmentation of images into objects using Definiens Earth software (formerly eCognition©). Object-oriented classification combines fuzzy logic, based on spectral, spatial and...

The main purpose of the Conservation Atlas of Wetlands is to develop a portrait of the wetlands of the St. Lawrence Valley using innovative mapping methods in order to favor bird conservation by helping land managers to make decisions about land use and bird habitat conservation. Another...
