| Summary | This abstract provides a summary and progress update of the nationwide long-period magnetotelluric field campaign in England, Southern Scotland and Wales. This field investigation is funded as part of the SWIMMR (Space Weather Instrumentation, Measurement, Modelling and Risk) N4 project, called SAGE (‘SWIMMR and Ground Effects). The SAGE project aims to provide a real-time model of ground electric field data across the UK, to assess the hazard posed to grounded technological infrastructure by large space weather events. The practicalities of conducting a nationwide geophysical survey alongside details of data acquisition and data processing are discussed. This contribution illustrates some of the findings of field investigations so far, including magnetotelluric impedance tensors, ground electric field data during space weather events between May 2021 and August 2022, and ground electric fields during geomagnetic storms modelled using new magnetotelluric impedance tensors. A brief description of future research areas based on the results of field investigations is also included. |
