Hydrogeological Regions provide a framework to introduce the regional hydrogeology of Canada and to connect apparently disparate studies into a broader framework. The hydrological regions are first order areas used to capture and summarize data that will help develop more detailed profiles of each region. Comparison of findings within and between regions will allow scalable extension to sub-regional and watershed scale mapping.Canada has been classified into nine principal hydrogeological regions. Each region is described briefly based on the following five hydrogeological characteristics (Heath, 1984):system components and geometry;water-bearing openings;rock matrix composition;storage and transmission;recharge/ discharge.The hydrogeological classification emphasizes major geological provinces and rock formations. Fundamental water-bearing openings and rock matrix properties help determine the quantity (storage), flux (transmission), and composition of formation waters. These same properties and any overlying sediment cover affect recharge/ discharge rates for regional formations. While regional attributes are general, a simple aquifer mapping scheme can further describe the nature and character of aquifers in each region. For example, general groundwater settings across the country could be described as has been done by USGS principal aquifers [1]. Thus the regional framework can potentially link from national scales to watershed scales by identifying typical aquifer types based on readily available geological maps that use water-bearing character as a common attribute.The nine hydrogeological regions include:CordilleraMountains with thin sediment over fractured sedimentary, igneous and metamorphic rocks of Precambrian to Cenozoic age. Intermontane valleys are underlain by glacial and alluvial deposits of Pleistocene age.Plains (Western Sedimentary Basin)Region-wide basin of sub-horizontal Paleozoic to Cenozoic sedimentary rocks are overlain by thick glacial deposits filling buried valleys. Incised post-glacial valleys provide local relief. Shallow gas, coal, and brines may occur.Canadian ShieldUndulating region of thin glacial sediment overlying complex deformed, fractured PreCambrian igneous, metamorphic and sedimentary rocks. Region contains several terrains: sedimentary basins, structural belts, and glacial-lacustrine basins.Hudson Bay (Moose River) BasinSedimentary basin of Paleozoic to Mesozoic sub horizontal carbonate and clastic sediment covered by surficial deposits, with low relief and poor drainage.Southern OntarioEastern Great Lakes region is underlain by gently-dipping Paleozoic, carbonate, clastic and gypsum-salt strata overlain by glacial sediments up to 200 m thick with tunnel valleys. Karst, bedrock valleys, shallow gas and brines are also important components.St. Lawrence LowlandsLowlands underlain by shallow-dipping Paleozoic sedimentary rocks and thick glacial sediment in glacial-marine basins. Appalachian and Precambrian uplands discharge water to valleys. Shallow gas and saltwater intrusion are possible.AppalachiaUpland to mountainous region with thin surficial sediment on folded Paleozoic sedimentary and igneous rocks. Range of rock types yields a wide range of water compositions. Valleys contain important alluvial aquifers.Maritimes BasinLowlands with flat-lying, Carboniferous clastic , salt, and gypsum rocks contain shallow coal deposits. Surface glacial sediment is thin and discontinuous. Salt water intrusion is possible.PermafrostArctic islands and most areas north of 60o contain frozen ground affects on groundwater flow. Diverse topography and geology define sub-regions of sedimentary basins and crystalline rocks. Glacial sediment is thin, discontinuous; local peat accumulations are significant.

These structure, isopach and zero edge files are part of a series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project.The series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project have been produced using 2 km equi-spaced modified grids generated from Golden Software’s Surfer 9 kriging algorithm. The dataset used to produce each of the maps in this series was created using data from several projects completed by the Ministry (Christopher, 2003; Saskatchewan Industry and Resources et al., 2004; Kreis et al., 2004; Marsh and Heinemann, 2006; Saskatchewan Ministry of Energy and Resources et al., 2007; Heinemann and Marsh, 2009); these data were validated and edited as required to facilitate correlations between the various regional projects. In addition, to minimize edge effects during contouring, the senior author also generated stratigraphic data from wells in adjacent jurisdictions.

Summer, Winter Alpine, and Winter Forest-Dwelling habitat model for caribou in the Itcha, Ilgachuz, and Rainbow Mountains of West-Central BC. This habitat model was developed using telemetry from the Itcha-Ilgachuz, Rainbow, and Charlotte Alplands Herds. [Season] field should be used to split the data out into separate summer, winter alpine, and winter forest-dwelling habitat models. Model development is detailed in _Apps, C. D., T. A. Kinley, and J. A. Young. 2001. Multi-scale habitat modeling for woodland caribou in the Itcha, Ilgachuz, and Rainbow mountains of west-central British Columbia.Wildlife Section, Ministry of Water, Land and Air Protection, Williams Lake, British Columbia, Canada_.

The Yukon Territory is underlain by a great variety of rock types ranging in age from Early Proterozoic to Recent and representing diverse environments including epicratonic basins, subsiding shelves, foreland basins, island arcs and deep ocean basins. Episodes of compressional and extensional deformation, transcurrent faulting, metamorphism and plutonism further complicate the map pattern. This complex geological record has been described in terms of the interactions of several terranes (large parts of the earth's crust which preserve a common geological record) with each other and with the margin of ancestral North America.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Annual and five-year (5YA) average wet deposition maps for the ammonium ion are available. The file formats include geodatabase files (*.gdb) compatible with geospatial software (e.g. ESRI ArcGIS) and KMZ files compatible with virtual globe software (e.g. Google Earth™). Maps can also be viewed online via Open Maps and the ArcGIS online viewer. Annual deposition from each site was screened for completeness using the following criteria: (1) precipitation amounts were recorded for >90% of the year and >60% of each quarter, and (2) ammonium concentrations were reported for >70% of the precipitation measured over the year and for >60% of each quarter. Five-year average wet deposition values are averaged annual deposition values with a completeness criterion >60% for the five-year period. Units for wet deposition fluxes are in kg of NH4 per hectare per year (kg ha-1 y-1). Sources of measurement data and spatial interpolation method are described here: https://doi.org/10.18164/e8896575-1fb8-4e53-8acd-8579c3c055c2.

Multi-Agency Ground Plot (MAGPlot) database (DB) is a pan-Canadian forest ground-plot data repository. The database synthesize forest ground plot data from various agencies, including the National Forest Inventory (NFI) and 12 Canadian jurisdictions: Alberta (AB), British Columbia (BC), Manitoba (MB), New Brunswick (NB), Newfoundland and Labrador (NL), Nova Scotia (NS), Northwest Territories (NT), Ontario (ON), Prince Edward Island (PE), Quebec (QC), Saskatchewan (SK), and Yukon Territory (YT), contributed in their original format. These datasets underwent data cleaning and quality assessment using the set of rules and standards set by the contributors and associated documentations, and were standardized, harmonized, and integrated into a single, centralized, and analysis-ready database. The primary objective of the MAGPlot project is to collate and harmonize forest ground plot data and to present the data in a findable, accessible, interoperable, and reusable (FAIR) format for pan-Canadian forest research. The current version includes both historical and contemporary forest ground plot data provided by data contributors. The standardized and harmonized dataset includes eight data tables (five site related and three tree measurement tables) in a relational database schema. Site-related tables contain information on geographical locations, treatments (e.g. stand tending, regeneration, and cutting), and disturbances caused by abiotic factors (e.g., weather, wildfires) or biotic factors (e.g., disease, insects, animals). Tree-related tables, on the other hand, focus on measured tree attributes, including biophysical and growth parameters (e.g., DBH, height, crown class), species, status, stem conditions (e.g., broken or dead tops), and health conditions. While most contributors provided large and small tree plot measurements, only NFI, AB, MB, and SK contributed datasets reported at regeneration plot level (e.g., stem count, regeneration species). Future versions are expected to include updated and/or new measurement records as well as additional tables and measured and compiled (e.g., tree volume and biomass) attributes. MAGPlot is hosted through Canada’s National Forest Information System (https://nfi.nfis.org/en/maps). ------------------------------------------------------LATEST SITE DISTURBANCES LAYER:------------------------------------------------------Shows the most recently recorded disturbance class at each MAGPlot site. These disturbance classes are broad categories, with more detailed disturbance types available in the full dataset.-----------NOTES:----------- The MAGPlot release (v1.0 and v1.1) does not include NL and SK datasets due to pending Data Sharing Agreements, ongoing data processing, or restrictions on third-party sharing.
