I am a current PhD student, funded by a NERC studentship, with a focus on glaciology. I received a Masters in Polar and Alpine Change from the University of Sheffield in 2017, after completing my undergraduate studies in Physical Geography at the University of Worcester in 2016.
I am interested in all aspects of glaciology, the cryosphere, remote sensing and geomorphology.
The following outlines my current work:
Surface melting of mountain glaciers: the effect of ice surface properties on melt rates
Latent and sensible turbulent fluxes are a fundamental energy exchange in glacial melt models and mass balance calculations, which become more important in cloudy and windy conditions (Fausto et al., 2016). Aerodynamic roughness (z0) is a key aspect in calculating turbulent fluxes, but it remains a primary source of error which varies considerably depending on the surface, time and scale over which it is measured (Munro, 1989; Brock et al., 2006). Several techniques are used to measure z0, including analysis of glacier surface microtopography; recent advances in topographical surveying allow the rapid acquisition of high-resolution elevation data, and have shown the potential to revolutionise the measurement and calculation of z0 (e.g. Smith et al., 2016; Quincey et al., 2017).
This project aims to reduce the uncertainty surrounding z0 by validating and improving the methods used to measure it. The overall goal is to better parameterise spatial and temporal variation in z0, with a view to upscaling the approach so that z0 can be predicted over much larger scales. We also hope to explore the possibility of incorporating distributed z0 values into existing glacial melt models.
Preliminary research questions:
- How accurately can z0 be measured over different ice surfaces using structure from motion photogrammetry or LiDAR?
- Can distributed measurements be acquired over larger scales, including glacier-scales (and beyond)?
- Can our findings be used to predict z0 from aerial/satellite data, and can they be incorporated into existing melt models?
