The BC87 dataset consists of magnetotelluric data from twenty-seven sites along a 150 km profile across resistive terrains in southeastern British Columbia. These data are skewed, sheared, shifted and twisted, and require our most advanced processing tools to sort them out prior to two-dimensional modelling. However, even after galvanic distortion removal three-dimensional effects are apparent in the data at some sites for certain period bands.
If you use these data in a publication, please inform me so that I can add it to the list below.
