The Canadian Permafrost Electrical Resistivity Survey Database (CPERS)

The Canadian Permafrost Electrical Resistivity Survey Database (CPERS) is a collection of electrical resistivity tomography (ERT) datasets collected in permafrost environments. The database currently contains sites in British Columbia, Newfoundland and Labrador, Northwest Territories, Quebec, Yukon, and Alaska. Each dataset provides information to interpret the presence and distribution of frozen and unfrozen ground along a profile where spatial extent and depth of investigation depend on the survey set-up. Metadata is currently available for 280 ERT surveys collected at 209 different profiles, with repeat surveys being conducted at 15 of those profiles. Raw ERT data is currently available for 123 surveys, while the remaining 157 datasets are currently embargoed and will be published within two years. Data were acquired between 2008-2022. Amalgamated site and borehole metadata are available as supplementary materials. This dataset will support a publication by Herring et al. (2023). The CPERS database project was funded by NSERC PermafrostNet.

DATA POLICY: In order to use any of these datasets you MUST review and adhere to the CPERS data policy, which can be found at https://data.permafrostnet.ca/cpers/data_policy.html.

ADDITIONAL RESOURCES: Please visit https://data.permafrostnet.ca/cpers/. This site includes an interactive map of survey locations where all datasets can be queried by several different parameters and processed data can easily be plotted. It also includes open-source ERT data processing tools and other helpful resources.
