"The 2017 Kaskattama (KSK) Highland magnetotelluric (MT) dataset was collected in northeastern Manitoba in a quiet geomagnetic period (with geomagnetic disturbance index Kp values of mostly <4), during which only one minor storm occurred. The high geomagnetic latitude of the survey, 65º N, resulted in the recorded MT data containing strong Pc1 micropulsation signals and auroral signals with a potential impact on the quality of MT responses derived from the data. The survey area is within 250 km of hydroelectric facilities in the Gillam area and associated strong sources of electromagnetic noise. Initial computation of MT responses using standard processing methods, such as magnetic field remote-references, yielded MT responses of only moderate quality"--Executive summary, page i.
