The Canadian Ice Service maintains a collection of Daily ice charts, Regional ice charts and Iceberg charts. These charts are available in GIF format and E00 Regional Charts only .

Results from temperature preference experiments demonstrated that individual personality was consistent and repeatability. Individual preferred and maximum avoidance temperatures were significantly reduced in hypoxia compared to normoxia. Standard metabolic rate increased with temperature and body mass. Patterns of projected habitat change suggest the spatial extent of the current distribution of Carmine shiner would shift north with global warming.

The contaminants in fish database is a compilation of contaminant data analysed from fish tissue at the Fresh Water Institute from 1970 to 2005. Data include lab number, region, analysis, organs, species, lake, form (whole fish, headon dressed, headless dressed), weight, and length and contaminant concentrations. Total mercury was the predominant contaminant measured. Results were expressed as ppm or ppb based on the parameter analyzed.

Each year, rotary screw traps (smolt wheels) are installed in the Kedgwick River, Upsalquitch River and main Restigouche channel from early/mid May to mid/late June. All traps are checked daily, and all fish species are counted. The majority of Atlantic salmon smolts are measured and a fraction are weighted. Everyday, Atlantic salmon smolts are tagged with unique streamer tags and released upstream of the trap they were caught in with the hope that a fraction of them will be recaptured so the trap efficiency and abundance can be estimated (capture-mark-recapture experiment).

These ice charts illustrate ice conditions at a particular moment in time. The ice information is presented using a standard international code, known as the Egg Code.

The following charts are available from the Canadian Ice Service:

-Daily Ice Charts
-Image Analysis Ice Charts

Canadian Anchorages and Anchorage Areas is comprised of four shapefiles which include anchorage areas (ACHARE) and single ship anchorages (ACHBRT). The shapefiles are either one with points and one with polygons for each of the two types of anchorages. These files are a comprehensive dataset of anchorages and anchorage areas in Canadian navigable waters. This dataset will be updated as needed.

This dataset is a contribution to the development of a kelp distribution vector dataset. Bull kelp (Nereocystis leutkeana) and giant kelp (Macrocystis pyrifera) are important canopy-forming kelp species found in marine nearshore habitats on the West coast of Canada. Often referred to as a foundation species, beds of kelp form structural underwater forests that offer habitat for fishes and invertebrates. Despite its far-ranging importance, kelp has experienced a decline in the west coast of North America.

This service provides routeing measures. These include established (mandatory) direction of traffic flow, recommended direction of traffic flow, separation lines, separation zones, limits of restricted routeing measure, limits of routeing measures, precautionary areas, archipelagic sea lanes (axis line and limit beyond which vessels shall not navigate) and fairways designated by regulatory authority.

Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate that shows the coverage of hydrographic charts produced by the Surveys and Mapping Branch of the Department of Mines and Technical Surveys, circa 1958. It also shows portions of three published sheets which illustrate the kinds of hydrographic charts available. The section entitled Inland Waters is part of Coast Chart 2303, Inland Waters, Great Lakes, Jackfish Bay to St. Ignace Island, Lake Superior. The Harbour Chart is part of Harbour Chart 3418, Vancouver Harbour.
