Air Monitoring Networks and Studies produce data that represent a wide variety of observations and measurements. Multiple data types (also called collections) can be produced by a single network and data collections can have contributions from multiple networks. The data are organised as follows: 1. Atmospheric Gases, 2. Atmospheric Particles, 3. Atmospheric Precipitation Chemistry, 4. Combined Atmospheric Gases and Particles 5. Special Studies of Atmospheric Gases, Particles and Precipitation Chemistry Networks and Studies contributing to the Canadian National Atmospheric Chemistry Database and Analysis system (NAtChem) are from Canadian federal and provincial networks (past and present) and also include U.S. historical networks (these data are not available elsewhere). Information about these contributing networks, for each of these collection and product groups, can be found in each network's description documentation.

Notice: This layer is out of date and scheduled to be retired October 31, 2026.Yukon First Nations and Tetlit Gwich'in settlement lands including both rural blocks (R-block) and Fee Simple lands of the First Nations that have ratified their agreements. Settlement land is land identified in a first nation's final agreement as settlement land of the first nation. There are three types of settlement land that a Yukon First Nation can own and manage: Category A: complete ownership of surface and subsurface; Category B: complete ownership of the surface only; Fee Simple: private ownership. This data was built using the 1:250,000 National Topographic Data Base (NTDB) as the base and the 1:30,000 signed Territorial Research Base Maps (TRBM) to define the boundaries.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps).

The Beaufort Regional Environmental Assessment-Marine Fishes Project (2012-2014) and Canadian Beaufort Sea-Marine Ecosystem Assessment (CBS-MEA, 2017-present) conducted by Fisheries and Oceans Canada provide offshore surveys of marine fishes and ecosystems on the Canadian Beaufort Shelf and slope in August and early September. The projects focus on integrating oceanography, food web linkages, physical-biological couplings and spatial and inter-annual variability, within the context of ongoing climate-driven change including enhanced Ocean Acidification. Sampling was conducted from the F/V Frosti at stations along transects spanning 20-1000 m. Zooplankton was collected using a bongo or multi-net system in conjunction with oceanographic and biogeochemical sampling.

Terrestrial Ecosystem Mapping (TEM) Project Boundaries (STE_TEM_PROJECT_BOUNDARIES_SVW) contains boundaries (study areas) and attributes describing each TEM project (project level metadata), plus links to the locations of other data associated with the project (e.g., reports, polygon datasets, plotfiles, field data, legends). This layer is derived from the [STE_TEI_PROJECT_BOUNDARIES_SP](https://catalogue.data.gov.bc.ca/dataset/1313fac7-2ea1-4c6b-995b-bd421b7ec3c6) layer by filtering on the PROJECT_TYPE attribute. Project Types include: TEM, NEM, TEMNSS, NEMNSS, TEMPRE, NEMPRE, TEMSEI, TEMSET, TEMTSM, TEMWHR, TEMSDM, TEMPRW, NEMPRW, and NEMSEI. TEM project boundaries should be used in conjunction with TEM detailed inventory polygons which divide the landscape into units according to a variety of ecological features including climate, physiography, surficial material, bedrock geology, soils and vegetation. TEM inventory polygons with full Resources Information Standards Committee (RISC) attributes can be accessed through the [Terrestrial Ecosystem Information (TEI) Data Distribution Packages](https://catalogue.data.gov.bc.ca/dataset/8fd15e4e-e7b1-4566-81d1-1ff8947bfd46). TEM inventory polygons with simplified and amalgamated (concatenated) RISC attributes can be accessed through the [Terrestrial Ecosystem Mapping (TEM) Detailed Polygons with Short Table Attribute Table Spatial View](https://catalogue.data.gov.bc.ca/dataset/0a83163b-a62f-4ce6-a9a1-21c228b0c0a3). **Current version**: v12 (2026-06-22)

This record contains results from stable isotope analysis of sediment samples including δ 13C (‰), δ 15N (‰), total N and total C collected in the Beaufort Sea.
