The National Ecological Framework for Canada's "Permafrost by Ecoprovince” dataset contains tables that provide permafrost information within the ecoprovince framework polygon. It provides permafrost codes and their English and French language descriptions as well as information about the percentage of the polygon that the component occupies. Permafrost is defined as a state of the ground, whether soil or rock, that remains at or below a temperature of 0° C for long periods (NRC, Permafrost Subcommittee, 1988). The minimum period is from one winter, through the following summer, and into the next winter; however, most permafrost has existed for much longer. This formal definition considers only the temperature of the ground, and thus permafrost is a strictly thermal phenomenon, and not a material. At temperatures below 0° C , almost all of the soil moisture occurs in the form of ground ice. Ground ice usually exists at temperature close to its melting point and so is liable to melt if the ground warms. The extent and nature of permafrost, including estimated ice content and typical ground ice forms are derived from the map "Canada - Permafrost" (Natural Resources Canada, 1995).

The National Ecological Framework for Canada's "Permafrost by Ecodistrict” dataset contains tables that provide permafrost information within the ecodistrict framework polygon.

The Permafrost Information Network (PIN) geotechnical borehole database combines existing database compilations into a standard structure. The standardized database was created to be accessible from the PIN web application as a data layer. Further information regarding data compilation can be accessed from the PIN web application.

This dataset uses RADARSAT Constellation Mission (RCM) Synthetic Aperture Radar (SAR) satellite images to identify open water regions within ice-covered rivers during winter, with the aim to assess hydrokinetic resources near remote communities reliant on diesel fuel for electricity generation. The data is processed with the HyRASS, a machine learning-based SAR image processing and classification algorithm.Disclaimer:This dataset was designed to identify open water regions within ice-covered rivers for assessing hydrokinetic resources near remote communities reliant on diesel fuel for electricity generation and is subject to the following limitations: • This dataset was derived from RADARSAT Constellation Mission (RCM) Synthetic Aperture Radar (SAR) satellite images. While these images are generally reliable, they are subject to inherent limitations, including resolution constraints, potential distortion, and occasional inaccuracies in real-time conditions capture. • The HyRASS algorithm is designed to pinpoint open water areas using satellite images, with a particular emphasis on RCM quad polarization (QP) imagery. This specialization means that its effectiveness depends on the accessibility of this specific type of imagery. Consequently, the data it produces might not cover a broad spectrum of time periods. For more reliable results, it's essential to classify areas more regularly, ensuring that detected open water regions are consistent over time.This dataset is intended for preliminary assessment and should not be the sole basis for making critical decisions or investments related to hydrokinetic energy projects. Further validation and in-depth analysis are strongly recommended, and users should conduct their own due diligence and additional research to verify the data accuracy and relevance for specific applications.

The toponymic features of the CanVec series include proper nouns designating places and representations of the territory. This data come from provincial, territorial and Canadian toponymic databases. They are used in the CanVec Series for cartographic reference purposes and vary according to the scale of display. The toponymic features of the CanVec series can differ from the Canada's official geographical names.The CanVec multiscale series is available as prepackaged downloadable files and by user-defined extent via a Geospatial data extraction tool.

Situated in the Gwich’in settlement Area (GSA), the Rat River is inhabited by anadromous Dolly Varden (Salvelinus malma malma) that are harvested by both Gwich’in and Inuvialuit beneficiaries. The harvest of Dolly Varden from the Rat River occurs during the summer at feeding areas along the coast (by the Inuvialuit) and during upstream migration in the Mackenzie Delta (by both Gwich’in and Inuvialuit). Dolly Varden stocks are co-managed under an Integrated Fisheries Management Plan (IFMP) whose signatories include Fisheries and Oceans Canada (DFO), Gwich'in Renewable Resources Board, Fisheries Joint Management Committee, and Parks Canada Agency. The Rat River Working Group, the co-management body that makes recommendations for harvest levels for Dolly Varden stocks in the GSA, has supported research activities that facilitate implementation of the IFMP, including studies to monitor harvest levels and assess population status. Population studies (e.g., abundance estimates, biological and genetic sampling) and coastal harvest monitoring activities allow for a comprehensive assessment of this stock. The data are used to inform co-management partners on the status of Dolly Varden from the Rat River.

This data record contains digitized maps recreated from the original report entitled Local Knowledge and local stocks: An Atlas of Groundfish Spawing in the Bay of Fundy published by The Centre for Community-Based Management, Extension Department, St. Francis Xavier University. These maps show where and when fishermen have caught developing and spawning, pollock, haddock and cod and the decline of these areas over time.Cite this data as: Graham, J., Engle, S., Recchia, M. 2002.
