Below the Bonnie Banks – investigating Lock Lomond’s subaqueous Quaternary landscape

given by Dr. Andrew Finlayson (Quaternary Geologist, BGS Edinburgh)

Abstract:
Loch Lomond is an iconic part of Scotland’s scenery, spanning landscapes of both Highland and Lowland character on either side of the Highland Boundary Fault.  From a Quaternary geological perspective, the wider Loch Lomond basin has a long history of research and forms a type area for a period of environmental change at the end of the last glacial cycle in Britain – the ‘Loch Lomond Stadial’.  However, there is still relatively little known about the submerged landscape below the loch surface.   This talk will give a brief overview of the Quaternary landscape evolution around Loch Lomond and then present new findings from multibeam bathymetry and shallow seismic profiles.  We will look at how these data add the loch’s glacial and postglacial story, and also what they tell us about more recent processes such as subaqueous landslides associated with shoreline infrastructure.
