The origin of bedrock mega-grooves in glaciated terrain

My PhD research is in glacial geomorphology and focusses on understanding the formation of bedrock mega-grooves. Mega-grooves are long, straight and parallel troughs in bedrock, which occur in palaeo and modern glaciated areas. Mega-grooves are regarded as landforms of erosion, thought to have formed subglacially, but there is uncertainty regarding the agents and processes that led to their formation, and also their age and glaciological significance. My project aims to address these uncertainties. Unlike other subglacial landforms, mega-grooves are a more rare occurrence and have received relatively little scientific attention, yet they hold the potential to advance our understanding of ice sheet behaviour and long-term landscape evolution.
