The Turkey Lakes Watershed Study (TLWS) was established in 1979 and is one of the longest running ecosystem studies in Canada. It is 10.5 km2 and is located approximately 60 km north of Sault Ste. Marie, Ontario at the northern margin of the Great Lakes – St. Lawrence forest region. Researchers from Natural Resources Canada, Environment Canada and Fisheries and Oceans Canada established the research watershed to evaluate the impacts of acid rain on terrestrial and aquatic ecosystems.

"The CNDSS collects, validates and maintains basic surveillance data on approximately 60 nationally notifiable diseases, dating back to 1924. Nationally notifiable diseases are infectious diseases that have been identified by the federal government and provinces and territories as priorities for monitoring and control efforts.

Provinces and territories voluntarily submit annual notifiable disease data, which are used to produce national disease counts and rates. Age-group and sex breakdown are presented from 1991 onward."

The Whitehorse Trough is a Mesozoic sedimentary basin in south-central Yukon that has been identified as an immature, gas-prone basin, based on a limited geoscience database. One hundred and seventy kilometres of regional, multi-channel, multi-component Vibroseis seismic reflection data were acquired in 2004 across the northern Whitehorse Trough, in order to improve understanding of its structural architecture.

This data provides the integrated cadastral framework for the specified Canada Land. The cadastral framework consists of active and superseded cadastral parcel, roads, easements, administrative areas, active lines, points and annotations. The cadastral lines form the boundaries of the parcels. COGO attributes are associated to the lines and depict the adjusted framework of the cadastral fabric.

An archive of 2D regional seismic and long period magnetotelluric data collected during 20 years of work under the LITHOPROBE project. Data are primarily onshore and cover widespread regions of Canada. Available data types include raw digital data, processed sections, and images of final sections, as well as auxiliary information required for analysis of the data.

This table is part of a series of tables that present a portrait of Canada based on the various census topics. The tables range in complexity and levels of geography. Content varies from a simple overview of the country to complex cross-tabulations; the tables may also cover several censuses.

Contained within the 4th Edition (1974) of the Atlas of Canada is a set of six maps showing the average daily minimum temperature and average daily maximum temperature for December, January and February.

Health characteristics, two-year period estimates, by age group and sex, Canada, provinces, territories, census metropolitan areas and population centres.

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 lifecycle in a flow-through system to nominal venlafaxine concentrations. During the 167–168 day exposure, no significant changes were observed in survival, or the weights and lengths of Fathead minnows. At maturity, there were no significant differences relative to controls in condition factor, liver-somatic index, or secondary sex characteristics in the venlafaxine exposed male or female fish.
