Abstract: This report distributes the 34 audiomagnetotelluric (AMT) and 46 broadband magnetotelluric (BBMT) stations collected in the Burwash Landing region, Yukon, by Quantec Geoscience Ltd. from October 8 to November 2, 2021. The technical report in Appendix 1 contains details of the acquisition process, processing and preliminary modelling products. The AMT and BBMT soundings are released here are as EDI files (Appendix 2), 2D modelling products are released as GDB, GRD, and XYZ files (Appendix 3), and 3D modelling products are released as GDB, VOXEL and XYZ files (Appendix 4). Geographic positioning of AMT and BBMT stations and electrodes are provided in GDB and CSV formats (Appendix 5). The products released herein were provided by Quantec Geoscience Ltd. The final preferred 3D inversion model incorporating extremely low frequency electromagnetic (Witter, 2020), AMT and BBMT data, as well as details of that 3D modelling process can be found in Tschirhart et al. (2022).
