Dr Eleanor Johnstone

Research interests:

My research centres on the interactions between the Greenland Ice sheets and the surrounding ocean. As part of the FjordMix project, I am developing and using numerical models to advance understanding of the impact of fjord processes on the interaction of Greenland’s tidewater outlet glaciers with the ocean. By better understanding the exchange of heat and freshwater during the interactions between the ice sheet and the surrounding ocean, we aim to improve predictions of ice loss, sea-level rise and ocean properties around Greenland.

Career history:

I have a background in fluid dynamics, with a mathematics degree from Imperial College London and a PhD in Applied Mathematics from the University of Manchester. My PhD research was split between modelling the shape of fluids in micro-channels (with Andrew Hazel and Oliver Jensen) and the structure underpinning high-Reynolds-number turbulence (with Phil Hall at Monash University, Melbourne). Since completing my PhD I completed a 6 month internship at MathWorks (Cambridge) working in the Parallel Computing Toolbox team, and have been a David Crighton Fellow at DAMTP, University of Cambridge with John Taylor, where I researched the stability of ocean fronts.

Active research projects:

I am part of the NERC funded project (2022-2025):
FjordMIX: Fjord Dynamics and Modulation of Ice/Ocean Exchange.
