Research

Unmanned Aerial Vehicle (UAV) observations are employed as observational platforms in many research areas of the earth sciences, and have found particular utility in glaciated regions. I am investigating the range of their potential and limits on their accuracy. I use near-daily UAV observations performed over three months (during the transition from late winter to mid summer), at Store Glacier, Greenland, to 1) model melange effect through backstress on Store Glacier's near terminus region, 2) determine general physical characteristics of ice melange, and 3) build a case study of how to properly constrain errors in UAV field campaigns. I am constructing point cloud representations of the glacier's pro-glacier melange environment, using photogrammetry and Structure from Motion techniques that are derived from the field of landform risk assessment. This work is undertaken with the University of Aberystwyth.
