- Profile
-
Jeremy Ely obtained his BSc in Geography from the University of Sheffield in 2011, where he stayed to undertake his PhD titled "Flow Signatures on the Bed and the Surface of Ice sheets" which was awarded in 2016.
Jeremy undertook a 4 year postdoc on the BRITICE-CHRONO project, as a research associate in ice sheet modelling and data interaction. He was then awarded a 5-year NERC Independent Research Fellowship, "A novel approach to constraining ice sheet models with glacial geomorphology."
Jeremy is now a Senior Lecturer, and leads the NERC highlight topic "Deplete and Retreat, the Future of Andean Water Towers."
- Research interests
-
The aim of Jeremy's research is to make data on past ice mass fluctuations useful for understanding the behaviour of glaciers and ice sheets in our warming world. As such, Jeremy has combined multiple different techniques to make insights into the following areas.
Water Resource Change in the Andes
I am principle investigator of the Deplete and Retreat project, which focuses on water resources across South America. This work has taken me across South America, where we have been installing weather stations and glacier monitoring equipment to improve our knowledge of high altitude environments. The team will integrate high resolution climate, glacier and hydrology models, to make hindcasts and forecasts of future water resources.
Glacial Geomorphology
I am interested in the formation of subglacial bedforms, the landforms which are produced at the sole of a glacier or ice sheet. My research led to the confirmation of a long held (40 year!) hypothesis that subglacial bedforms belong to a morphological continuum. I have also dug holes into subglacial bedforms, and flown UAVs over them in order to work out how they form. I am also interested in the formation of meltwater related landforms.Palaeo-ice sheets
The action of the ice sheets which existed during the last ice age can be deciphered from the landforms and sediments they left behind. I worked on BRITICE-CHRONO, where my job was to make numerical ice sheet models interact with data pertaining to the last ice sheet to cover Britain and Ireland. I also work alongside the PALGLAC team, helping to improve model-data interactions in palaeoglaciology.Ice Sheet Surfaces - Structures and Hydrology
I was part of the team which discovered the widespread occurrence of meltwater streams on the surface of Antarctica. This surprising discovery has large implications for the future of the ice sheets in Antarctica. Ongoing work is looking in more detail at the dynamic influence meltwater has on ice flow on the Antarctic Peninsula. Beyond water, I am interested in the formation of beautiful ice surface landscapes.
