About
Engineer turned physical oceanographer with an interest in data science.
Physical Oceanographer
I recently completed my PhD in physical oceapography at the Oceans Graduate School at the University of Western Australia.
- Current city: Perth, Australia
- Email: williamedge88@gmail.com
- Degree: PhD
- Employment status: Available from December
My thesis focused on the analysis of complex and noisey observation datasets and application of data science techniques to infer physical characteristics. Since completing my PhD I have been working on analysing a complex multi-year multi-mooring dataset to better understand and forecast currents on the Northwest shelf of Australia. Prior to (and during) my studies I worked as a coastal engineer.

In Situ Estimation of Erosion Model Parameters Using an Advection‐Diffusion Model and Bayesian Inversion
JAMES (Journal of advances in modelling of earth systems)
Combining detailed observations with a 1D model to estimate unobserved processes and parameters. This paper approached a long-standing issue in sediment transport with Bayesian inference techniques. It was chosen as an editor's highlight on EOS.
Calibrated suspended sediment observations beneath large amplitude non‐linear internal waves
JGR: Oceans
Novel observations of large NLIW (solitions) propagating over a muddy seafloor. Acoustic backscatter was converted to an estimate of sediment mass concentration using in-situ and laboratory techniques. Hysteresis makes it clear that sophisticated techniques are required for good analysis.
Characterisation of suspended sediment dynamics under nonlinear internal waves (in preparation)
JGR: Oceans
Estimation of the contribution of different fluxes to the total resuspended sediment budget under NLIW (solitons). This chapter of my thesis is currently being prepared for submission, see the original version in Chapter 3 of my thesis online.
Daily timing of low tide drives seasonality in intertidal emersion mortality risk
Frontiers in Marine Science (co-author)
A detailed look at how tides control not only the reef platform height, but also the risk of coral moratility by hot and cold temperature emersion. Interesting variability at 8 sites around Australia can be connected to differences in physical and biological reef development.
