Dr Felicity Graham is a researcher at the Institute for Marine and Antarctic Studies. She works within the ice sheet group as part of the Antarctic Gateway Partnership. In particular, she is interested in modelling processes and conditions at the base of East Antarctic ice sheets. Her modelling work, along with existing observations, will help guide future field campaigns in Antarctica, such as the quest for oldest ice.

Biography

Felicity completed her PhD through the University of Tasmania and CSIRO, evaluating models of the oceanic processes underlying El Nino-Southern Oscillation. She has also collaborated with researchers from CSIRO and the Geophysical Fluid Dynamics Laboratory, Princeton, USA, and spent much of her PhD at Monash University, Melbourne, Australia. In 2012 she was selected to participate in the Geophysical Fluid Dynamics Fellowship Program at the Woods Hole Oceanographic Institute, USA. Her work during this 12-week program focussed on wave forms originating under quasi-geostrophic flow at the equator.

Research Themes

Felicity's research aligns to the University's research theme of Marine, Antarctic, and Maritime, under the key research area of Southern Ocean and Cryospheric Change. Her research interests include advancing understanding of the processes at the base of East Antarctic ice sheets through improved modelling of basal conditions. Felicity's research into basal processes will guide assessment of the risk of rapid retreat of East Antarctic ice sheets due to warming and atmospheric/oceanic changes.

Improving the description of ice flow in numerical models of Antarctica and Greenland (2016)$14,993
Description
Sea level rise is one of the great challenges facing society, with a projected increase of up to 0.98 m in mean sea level by the end of the 21st century (Church et al., 2013). The largest source of uncertainty in sea level rise projections is in the estimate of ice mass loss from the Antarctic and Greenland ice sheets. This is in part due to overly simplified numerical descriptions of ice dynamic processes in ice sheet models, which can lead to underestimates of ice velocities by up to an order of magnitude (Treverrow et al., 2015). This project aims to improve the numerical description of ice flow in three state-of-the-art ice sheet models. We will use an ice flow relation that has been developed from extensive laboratory testing and that characterises all regimes of ice flow (Budd et al., 2013). We will compare the improved ice flow relation with the formulation currently implemented in most leading ice sheet models over idealised and realistic domains, the results of which will form the basis for two scientific papers. This work is of international significance as the results will be incorporated into three ice sheetmodels widely used by the international research community. An important consequence of our study is an advancement in ourunderstanding of estimates of ice mass loss through a more complete characterisation of ice dynamic processes. Through this improved understanding of ice mass loss, our work will lead to a reduction in the uncertainties associated with the contribution of Antarctica and Greenland ice mass loss to future sea level rise - one of the greatest climate change issues impacting humankind.

Assessing the sensitivity of ice sheet mass flux to high resolution bed topography (2016)$0
Description
Over the past decade, ice mass has been discharging from the Antarctic ice sheets at an increasing rate, contributing to global sea level rise. The sensitivity of processes driving mass flux from the Antarctic ice sheets is relatively poorly understood, despite improvements in the capabilities of ice flow models in capturing ice sheet dynamics. This is partly because input parameters to ice flow models, such as bed topography, are of too low resolution to adequately resolve processes that contribute to mass flux. This project will investigate the sensitivity of ice sheet mass flux to bed topography resolution and basal traction. Bed topography data from a recently generated high resolution digital elevation model of the Totten Glacier will be subsampled in a series of perturbation experiments using a state-of-the-art ice sheet model designed for parallel performance. The results will inform our understanding of basal processes in ice sheets, ultimately reducing uncertainty associated with the contribution of Antarctic ice sheets to future projections of sea level rise.
