Session 15 - Ground-based Operational and Infrastructure Impacts of Space Weather

Ellen Clarke (BGS), Gemma Richardson (BGS)
Friday 01/12, 9:45 - 13:00

KEYWORDS - Ground-effects, Geomagnetically Induced Currents (GIC), electrical power networks, pipelines, railway signalling, geophysical prospecting, measurement-while- drilling (MWD)

The effects of Space Weather on the ground, such as unwanted geomagnetically induced currents in power systems and railway signalling systems, pipe-to-soil potentials in pipelines, increased error in, or cancellations of, aeromagnetic surveys and reduced drilling accuracy of measurement while drilling tools are all reasonably well known and documented. This does not mean to say, however, that the measurement, modelling, prediction and mitigation of these ground effects have been successfully resolved to the satisfaction of all industries affected. This session seeks contributions from engineers and researchers alike that focus on any aspect of space weather ground effects, including monitoring, modelling, prediction and mitigation. Presentations that advance our understanding of the impacts on operations and infrastructures and those where key, unresolved problems are identified will be especially welcome.
