Hydrography (HY) Iceland is one of 12 themes in the European Location Project (ELF). The purpose of ELF is to create harmonised cross-border, cross-theme and cross-resolution pan-European reference data from national contributions. The goal is to provide INSPIRE-compliant data for Europe. A description of the ELF (European Location Project) is here: http://www.elfproject.eu/content/overview Encoding: INSPIRE version 4

Province-wide SDE layer showing licensed water sources (streams and lakes), under the Water Act, (current and historical), not captured (displayed) on TRIM base mapping (or Freshwater Atlas base mapping). Includes an attribute for the internal Source Code number, which is associated with the (E-Licensing) stream name.

Point features showing the locations of groundwater wells with pumping test information and/or aquifer parameter data. Some wells may have more than one pumping test record. Further context regarding the pumping tests and analysis are provided with the well records in GWELLS (https://apps.nrs.gov.bc.ca/gwells/).

Hydrographic Annotation based on the 1:50,000 scale Canadian National Topographic Series of Maps.

Watershed polygons of Third Order and greater based on the Strahler Stream Order classification method and the 1:50,000 scale Canadian National Topographic Series of maps.

Contains all primary and secondary matches between 1:20K and 1:50K waterbody polygons. This attribute table links the new Freshwater Atlas watershed codes with the existing 1:50K Watershed Atlas watershed codes for cross reference purposes

The “Major Drainage Systems of the AAFC Watersheds Project - 2013” dataset is a geospatial data layer containing polygon features representing the three (3) major drainage system basins of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. The Project area has been split according into which body of water it drains: the Arctic Ocean, Hudson Bay or Gulf of Mexico.

Figure 4-16 Map showing the magnitude of change in diatom assemblages for downcore samples, with beta diversity used as a measure of the compositional differences between samples at different depths along the core. Boundaries for the beta diversity categories are based on distribution quartiles (0-0.1, 0.1-1.24, 1.24-1.5, >1.5), where the lowest values (blue dots) represent the lowest degree of change in diatom assemblage composition along the length of the core in each lake.

Collection of monitoring products of river ice roughness from current and past winter seasons throughout Canada as monitored by Natural Resources Canada using satellite imagery. This collection of cartographic products regroups river ice state monitoring products and their associated footprints. Three visualization timeframes are available: - **[Active Monitoring of River Ice in Canada](https://open.canada.ca/data/en/dataset/7b210c58-2fc7-47c5-8b8a-2605c77d725c)** - **[River Ice in Canada - Current](https://open.canada.ca/data/en/dataset/8ca6f047-ddef-43d7-81c2-47654f4c69bd)** - **[River Ice in Canada - Archive](https://open.canada.ca/data/en/dataset/5e6b40bf-299f-4e05-87c8-d10b9c8210f9)**

Long-term freshwater quality data from federal and federal-provincial sampling sites throughout Canada's aquatic ecosystems are included in this dataset. Measurements regularly include physical-chemical parameters such as temperature, pH, alkalinity, major ions, nutrients and metals. Collection includes data from active sites, as well as historical sites that have a period of record suitable for trend analysis. Sampling frequencies vary according to monitoring objectives. The number of sites in the network varies slightly from year-to-year, as sites are adjusted according to a risk-based adaptive management framework. The Great Lakes are sampled on a rotation basis and not all sites are sampled every year. Data are collected to meet federal commitments related to transboundary watersheds (rivers and lakes crossing international, inter-provincial and territorial borders) or under authorities such as the Department of the Environment Act, the Canada Water Act, the Canadian Environmental Protection Act, 1999, the Federal Sustainable Development Strategy, or to meet Canada's commitments under the 1969 Master Agreement on Apportionment.
