Johnny graduated from the University of Nottingham with a degree in Geography in June 2012. He then started a master’s degree at the Scott Polar Research Institute, University of Cambridge in October 2012 where he developed an interest in glaciology. Johnny is now a PhD student at Aberystwyth University where he investigates 1) the short-term dynamics of marine-terminating glaciers in Greenland and 2) the albedo of the Greenland Ice Sheet using unmanned aerial vehicles (UAVs). He is funded by the Aberystwyth University Department of Geography and Earth Sciences Doctoral Career Development Scheme (DCDS).

The primary aim of Johnny’s PhD is to deploy a fixed-wing UAV (http://users.aber.ac.uk/nns/research/uav/greenlanddebrief/basecamp.gif) over the Greenland Ice Sheet. The UAV was developed by Dr. Neal Snooke and built in Aberystwyth University. It currently has the ability to fly autonomously for 70 km and can carry a digital camera, pyranometer and several GoPros. More information can be found in the sections below.
A 3 month field campaign in the summer of 2014 resulted in the completion of 60 surveys of Store Glacier, West Greenland and 25 surveys of the Dark Snow (http://darksnow.org/) camp. The images obtained from these surveys can be processed using stereophotogrammetry to produce high resolution, georeferenced orthophotos and digital elevation models. These products allow the investigation of glacial processes at high spatial and temporal resolution.
In the 2014/2015 academic year, Johnny will be leading two Environmental Earth Science (F640) tutorials and demonstrating in the following modules:
- EAM1120 – Advanced Research Skills 1: science communication and data analysis
- EA201410 – Hydrochemistry
- GG21710 – Analysis of Geographical Data
